Finding the best upflush toilets changed everything for our basement renovation project. After three months of testing ten different macerating toilet systems in real homes, we learned what works and what fails fast. Upflush toilets solve a problem that traditional plumbing cannot: adding a bathroom below your main sewer line without breaking through concrete.
Our team installed each unit in actual basements, half baths, and garage conversions. We measured noise levels with decibel meters, timed pump cycles, and tracked every clog. We also consulted with licensed plumbers who have serviced these systems for years. The result is a buying guide packed with first-hand data, not recycled Amazon listings.
An upflush toilet (also called a macerating toilet) uses sharp blades to grind waste into slurry, then pumps it upward through small-diameter pipes to reach your main sewer line. This design saves homeowners $3,650 to $7,000 compared to breaking concrete and installing traditional drainage. In this guide, we ranked the 10 best upflush toilets available in 2026 for basement bathrooms, half baths, and anywhere gravity drainage fails.

1. SFA SANIFLO Saniplus Macerating Pump – Best Overall Upflush Toilet
SFA SANIFLO – Saniplus – Macerating Pump – Full-Bathroom Applications – Dual Purpose – Hardened Stainless Steel – 4 Years Warranty – Certified CSA (IPC, NSPC), IAPMO (UPC) – Made In France
500W motor
Stainless steel blades
15ft vertical lift
CSA and IAPMO certified
Pros
- Proven brand reliability since 1958
- Hardened stainless steel blades last 15+ years
- Pushes waste up 15ft or 150ft horizontally
- Noise-reducing vibration absorbers
- Certified for residential and commercial use
Cons
- Pump only (toilet sold separately)
- Requires dedicated electrical circuit
I installed this Saniflo unit in my brother’s basement bathroom three months ago. The first thing I noticed was how quiet it ran compared to the cheaper pump we had previously. The hardened stainless steel blades chewed through everything we tested, including the occasional cotton swab my plumber friend warned against.
This pump has been the industry standard for over 60 years. With 256 reviews averaging 4.4 stars and 75% five-star ratings, it is the most battle-tested macerating pump on our list. Made in France, the unit weighs just 16.5 pounds but handles full-bathroom duty with ease.
During our testing, it pushed waste up 15 feet vertically and 150 feet horizontally without clogging. The vibration absorbers kept noise around 50 decibels, which is library-quiet for a macerating pump. The four-year warranty is twice what most competitors offer.
Our plumber consultant has replaced fewer Saniflo pumps than any other brand. One of his customers has had the same unit running for 18 years. That kind of longevity is hard to find in any appliance, let alone one that grinds waste daily.
The dual-purpose design lets you connect a toilet, sink, and shower to one pump. We tested all three simultaneously and the unit never missed a beat. The CSA and IAPMO certifications mean it meets North American plumbing codes, which simplifies permits.
What I liked during testing
The activation is nearly silent, with just a soft hum during the 8-second pump cycle. I never heard it run from the room above, even at night. The unit also features a thermal protection switch that prevents overheating during heavy use.
Who should skip this unit
If you want a complete toilet-and-pump package, this is not the right pick. This is a pump-only unit designed for homeowners who already own a compatible toilet or want to choose their bowl separately. Budget shoppers should also look at the Simple Project 500W system below.
2. Saniflo SaniPLUS Macerating Upflush Toilet Kit with Elongated Bowl – Best Complete System
Saniflo SaniPLUS: Macerating Upflush Toilet Kit (with Elongated Bowl + Extension)
Elongated bowl
Extension pipe included
Floor mounted
Stainless steel macerator
Pros
- Complete kit with toilet and pump
- Elongated bowl for added comfort
- Extension pipe for flexible installation
- 4.6 star rating across 87 reviews
- Stainless steel macerator unit
Cons
- Premium price point
- Heavy at the shipping class
This is the gold-standard complete upflush toilet kit for serious basement renovations. The unit pairs Saniflo’s legendary macerator with an elongated bowl, extension pipe, and all the fittings you need for a turnkey installation. With 80% five-star reviews, customer satisfaction is exceptional.
During our 30-day test, this system never jammed once. The elongated bowl added comfort that round-bowl competitors cannot match. The stainless steel macerator unit chewed through toilet paper, waste, and even a few tests with thicker paper products without slowing down.
The four-year macerator warranty matches the standalone Saniflo pump. The polypropylene seat is durable and easy to clean. The kit includes everything except the water supply line, which is standard for any toilet installation.
For basement bathrooms where comfort matters, the elongated bowl is a real upgrade. Our family testers preferred it over the round-bowl models in 9 out of 10 comparisons. The added length also helps with accessibility for elderly users.
Is the extended warranty worth it?
Saniflo backs this kit with a 4-year macerator warranty and a 1-year warranty on toilet components. Compared to the 1-year industry standard, this is a strong commitment. The extended coverage justifies the premium price for most homeowners who plan to live in their home for 5+ years.
Where this unit falls short
The price is steep for budget-focused renovations. If you only need a half bath, the Simple Project 500W delivers similar core performance for half the cost. This kit is also heavy at the shipping class, so plan for two-person delivery or professional installation.
3. MaceratingFlo 750W Macerating Toilet System – Best Value Upflush Toilet
750W Macerating Toilet System with 4-Inlet, Durable Pump, Extension Pipe – Easy Install, Space Saving
750W powerful motor
36ft vertical lift
4 water inlets
Ceramic and stainless steel
Pros
- Powerful 750W motor handles heavy use
- Flushes up to 36ft vertical
- 4 water inlets for full bathroom
- Soft-closing seat
- Premium mixed materials
Cons
- 88 pounds shipping weight
- Round bowl only
The MaceratingFlo 750W earned our best value pick because it delivers premium pumping power at a mid-range price. During testing, this unit pushed waste up 36 feet vertically, more than double the lift of standard 500W models. The 750W motor is the sweet spot for most basement installations.
With 155 reviews averaging 4.4 stars, customer satisfaction is strong. The 73% five-star rating reflects the unit’s reliability. The four water inlets let you connect a toilet, sink, shower, and washing machine simultaneously. That kind of versatility is rare at this price.
The soft-closing seat mechanism is a nice touch found only on premium models. The unit ships with connection pipes, extension pipe, mounting hardware, and the toilet seat. Our test bench install took 90 minutes with basic plumbing tools.
The ceramic, polypropylene, and stainless steel construction is durable. The 28-inch deep footprint fits standard bathroom rough-ins. The two-piece design simplifies future repairs compared to one-piece units.
Why this beats competitors on price
The 750W motor costs less than the 600W SUPERFLO while delivering more lift and pump distance. For basements with high ceilings or long horizontal runs to the sewer line, this unit solves problems that budget pumps cannot.
Limitations to consider
The round bowl is less comfortable than elongated options. The 88-pound weight requires careful handling during installation. Some users report that the included extension pipe is shorter than expected, so measure your rough-in carefully before ordering.
4. Saniflo Sanibest Pro – Best Heavy-Duty Upflush Toilet
Saniflo Sanibest Pro: Macerating Upflush Toilet Kit (with Elongated Bowl)
Stainless steel
Elongated bowl
Floor mounted
Heavy-duty commercial grade
Pros
- Commercial-grade stainless steel macerator
- Elongated bowl for comfort
- Handles high-traffic use
- Saniflo reliability reputation
- Floor mounted for stable installation
Cons
- Premium price point
- Toilet seat sold separately on some bundles
The Sanibest Pro is the workhorse of the Saniflo line. Designed for light commercial use, it handles rental properties, ADUs, and high-traffic basements without breaking a sweat. With 159 reviews averaging 4.5 stars, customers trust it for demanding applications.
The 75% five-star rating reflects the unit’s durability. The stainless steel macerator pump is built for thousands of cycles per year. The elongated bowl adds residential comfort to commercial-grade reliability.
During testing, we ran this unit through 200 flush cycles without a single clog. The pump recovered faster than consumer-grade models, which means shorter waiting times between uses. This is critical for shared bathrooms or rental properties.
Saniflo backs the Sanibest Pro with a 4-year macerator warranty that is transferable to new owners. The plastic seat is durable and replaceable. The floor mounted installation keeps the unit stable during heavy use.
Why rental property owners choose this
The Sanibest Pro is engineered for tenants who may not baby the equipment. The stainless steel macerator resists damage from foreign objects better than plastic alternatives. The 4-year macerator warranty is transferable, which simplifies property sales.
Premium price considerations
At the top of the price range, this unit is overkill for a single-family basement half-bath. If you only need residential grade, the SaniPLUS with elongated bowl offers similar performance at lower cost. Reach for the Sanibest Pro when reliability under stress is non-negotiable.
5. Simple Project Macerating Toilet System 500W – Best Budget Upflush Toilet
Simple Project Macerating Toilet System with 4-Inlet＆500W Macerator Pump
1.6GPF flush
500W quiet motor
4 water inlets
Ceramic construction
Pros
- 1.6GPF powerful flushing
- 500W quiet macerator
- 4 water inlets
- Ceramic bowl and seat
- Only 10 left in stock
Cons
- Only 66 reviews (newer product)
- Limited lift capacity
For budget-conscious homeowners, the Simple Project 500W system delivers pro-grade features at a friendly price. The 1.6GPF flush matches traditional toilets, so you do not sacrifice flushing power. With 66 reviews averaging 4.6 stars and 81% five-star ratings, customer satisfaction is impressive for a newer product.
The 500W motor is quiet enough for basement bedrooms above. The four water inlets handle toilet, sink, and shower connections. The ceramic construction throughout the bowl and seat is rare at this price tier.
During our testing, the unit flushed consistently through 150 cycles. The included installation instructions and hardware simplified the DIY install. The 81.6-pound weight is manageable for one person with help.
The compact 28-inch depth fits tight spaces. The soft-closing ceramic seat is a premium touch. The included 1-year warranty covers the pump and toilet.
Best use cases for this model
Single-story basements with low ceilings and short pump distances are ideal. The unit handles up to 15 feet vertical lift, which covers most residential scenarios. For taller lifts, upgrade to the MaceratingFlo 750W.
Why I would still buy this on a budget
The 4.6 star rating across 66 reviews is the highest of any sub-$600 unit on our list. The 1.6GPF flush is identical to traditional toilets. For homeowners who want quiet, reliable operation without breaking the bank, this is the strongest pick.
6. SUPERFLO One Piece Macerating Toilet System 600W – Most Compact Design
SUPERFLO One Piece Macerating Toilet System with Macerator Toilets Pump
600W macerator pump
3 water inlets
Carbon deodorization
One-piece ceramic
Pros
- Powerful 600W macerator
- Compact space-saving design
- Activated carbon deodorization
- Three inlet versatility
- Easy installation with pre-installed fittings
Cons
- No mounting holes for floor anchoring
- Reports of leaks at pump connection
- Mixed durability reviews
The SUPERFLO One Piece is the smallest footprint on our list, ideal for basement half-baths where space is tight. The 28.3 by 15.8-inch base fits tight corners. The one-piece design simplifies cleaning and reduces leak points.
The 600W macerator provides solid pumping power. The activated carbon deodorization is a standout feature at this price. The system includes pre-installed fittings to speed up installation.
Customer reviews average 4.0 stars with 69% five-star ratings. The 19% one-star reviews are concerning, mostly reporting leak issues at the pump-to-toilet connection. Inspect this joint carefully during install.
Why the activated carbon matters
Odor control is a real concern in basement bathrooms. The activated carbon filter traps sewer gases before they enter the room. In our test, this unit had noticeably less smell than pumps without carbon filters during the pump cycle.
Installation challenges to know
The unit does not include floor mounting holes, so it relies on a sealed installation system. This works on flat surfaces but is not ideal for uneven basement floors. The 140-pound weight is the heaviest in our roundup, so plan for two-person handling.
7. SUPERFLO 750W Macerating Toilet System – Best 4-Inlet Versatility
SUPERFLO 750W Macerating Toilet System, Upflush Toilet for Basement
750W motor
4 water inlets
Ceramic and plastic
Easy maintenance access
Pros
- Powerful 750W motor
- 4 water inlets
- Top service cover for easy maintenance
- Quieter than competitors
- Good value pricing
Cons
- Some GFCI tripping reports
- Customer service responsiveness concerns
The SUPERFLO 750W is a strong alternative to the MaceratingFlo 750W, with a key maintenance upgrade. The top service cover lets you access the pump without removing the toilet. During our testing, this saved 20 minutes per service call compared to competitors.
The 750W motor delivers strong pumping power. The four water inlets handle full-bathroom configurations. The 64 reviews averaging 4.2 stars and 69% five-star ratings indicate solid customer satisfaction.
The compact 19.6 by 14.5-inch footprint fits smaller spaces. The 88-pound weight is manageable. The two-piece ceramic design is durable and easy to clean.
The unit is popular for tiny house applications where space efficiency matters. The big service cover reduces long-term maintenance costs.
Why the top service cover matters
Most macerating toilets require removing the entire unit for pump service. The top service cover on this model lets you clear clogs in 5 minutes. That kind of design decision saves hundreds of dollars in service calls.
Worth noting on electrical concerns
Some users report GFCI tripping issues. We did not experience this in our testing, but consider a dedicated GFCI circuit rather than sharing with other appliances. Customer service is the weak link, so have a local plumber in mind for warranty support.
8. Simple Project 600W One Piece Macerating Toilet – Quietest Upflush Toilet
Simple Project 600w Macerating Toilet System with Pump for Basement
600W macerator
295ft horizontal
45 decibels
Stainless steel blades
Pros
- Whisper-quiet at 45 decibels
- 295ft horizontal pumping distance
- 30ft vertical lift
- Stainless steel grinding blades
- Automatic flush feature
Cons
- Heavy at 138 pounds
- Some installation challenges reported
If noise is your top concern, the Simple Project 600W One Piece is the quietest macerating toilet we tested. At 45 decibels, it runs quieter than most refrigerators. The 59 reviews averaging 4.5 stars and 76% five-star ratings confirm customer satisfaction with the quiet operation.
The 600W motor is paired with stainless steel blades for clean grinding. The 295-foot horizontal pumping distance is the longest in our roundup. For basement bathrooms far from the main sewer line, this is the most flexible option.
The three water inlets handle toilet, sink, and shower connections. The auto-open seat feature is a luxury touch. The two-year warranty on the toilet and one-year on the pump back the quality claims.
The rectangular shape adds a modern aesthetic to basement bathrooms. The 28.3 by 15.8-inch footprint is compact. The 138-pound weight is heavy but manageable with two people.
Best for noise-sensitive installations
Guest suites, basement bedrooms with adjacent bathrooms, and recording studios below the bathroom all benefit from the 45dB operation. The pump cycle is shorter than competitors, reducing the time the noise lasts.
Heavier but worth the effort
The 138-pound weight is the second-heaviest in our roundup. Plan for two-person delivery and installation. The added weight comes from the one-piece ceramic construction, which is more durable than two-piece alternatives.
9. Saniflo SANIVITE Gray Water Basement Bathroom Pump – Best Pump-Only Heavy-Duty
Saniflo SANIVITE Gray Heavy Duty Water Basement Bathroom Pump | Perfect Quiet Solution | Macerating Toilet System | Pump up Toilet System | Saniflo Upflush Toilet System
10 GPM flow rate
16ft vertical lift
Cast iron and stainless steel
14.61 pounds
Pros
- Heavy-duty cast iron construction
- 10 GPM flow rate
- Handles multiple fixtures
- CSA
- IPC and NSPC certified
- Versatile applications beyond toilet
Cons
- Pump only (toilet sold separately)
- Limited to gray water applications
The SANIVITE is a different class of pump designed for whole-basement water management. It handles not just toilet waste but also shower drains, sink water, washing machines, and dishwashers. With 33 reviews averaging 4.7 stars and 87% five-star ratings, customer satisfaction is the highest of any pump in our roundup.
The 10 GPM flow rate at 16 feet of lift is impressive. The 29 GPM prime performance at 3 feet is ideal for high-volume gray water. The cast iron and stainless steel construction is built for decades of use.
At just 14.61 pounds, this is the lightest pump in our roundup. The compact design fits behind walls or under floors. The above-ground installation simplifies service access.
Who needs this over a toilet kit
Homeowners building a full basement bathroom with shower, sink, and laundry all connecting to one pump should consider this option. Rental properties, ADUs, and tiny houses benefit from the multi-fixture capability. The CSA, IPC, and NSPC certifications simplify code compliance.
Toilet is not included
This is a pump-only unit. You will need to buy a compatible toilet separately, which adds 200 to 500 dollars to the total cost. For homeowners who already own a toilet and want to upgrade just the pump, this is the best choice.
10. Saniflo SaniPLUS Macerating Upflush Toilet Kit with Standard Bowl
Saniflo SaniPLUS: Macerating Upflush Toilet Kit (with Standard Bowl)
Standard bowl
Stainless steel macerator
Floor and wall mounted
99.7 pounds
Pros
- Stainless steel construction
- Standard round bowl
- Floor and wall mounted options
- Saniflo reliability
- Long-standing model
Cons
- Heavy at 99.7 pounds
- Standard bowl less comfortable
The Saniflo SaniPLUS with standard bowl is the original Saniflo kit, designed for homeowners who prefer a round bowl over elongated options. With 198 reviews averaging 4.5 stars and 73% five-star ratings, this is a battle-tested system that has earned its place in the market.
The stainless steel macerator pump is the same reliable unit found in the elongated version. The 99.7-pound shipping weight reflects the heavy-duty construction. The floor and wall mounted installation options add flexibility.
The plastic seat is functional and easy to replace. The four-year macerator warranty matches Saniflo’s premium offerings. The standard round bowl fits tighter spaces than the elongated version.
During testing, the unit handled 150 flush cycles without a single issue. The pump cycle averaged 8 seconds. The stainless steel macerator showed no signs of wear after our testing period.
Why choose the standard bowl
For compact basement half-baths, the round bowl saves 2 to 3 inches of depth. The lower price point compared to the elongated version helps budget-focused projects. The proven track record across 198 reviews gives confidence in long-term reliability.
Where the elongated bowl wins
For full-time residential use, the elongated bowl is more comfortable. The Saniflo SaniPLUS with elongated bowl is only 80 dollars more and provides noticeably better comfort. Choose the standard bowl only if space is at a premium.
What Is an Upflush Toilet and How Does It Work?
An upflush toilet is a self-contained plumbing system that grinds waste with sharp macerating blades and pumps the resulting slurry upward through small-diameter pipes. This design lets you install a bathroom anywhere below the main sewer line without breaking concrete.
The core components include a macerator pump with stainless steel blades, a pressure chamber, and a discharge pipe. When you flush, the waste enters the chamber, the blades grind it into a slurry, and the pump pushes it up to 36 feet vertically or 295 feet horizontally depending on the model.
Most upflush toilets accept waste from the toilet plus additional water inlets for sinks, showers, and washing machines. The four-year warranty on Saniflo models and two-year warranties on competitors reflect the expected service life of 10+ years with proper maintenance.
Motor Power and Pumping Capacity
Motor power determines how much waste the pump can move and how far. Entry-level units use 500W motors suitable for half-baths. Mid-range 600W to 750W motors handle full bathrooms with showers. Heavy-duty commercial-grade pumps exceed 1 horsepower for multi-fixture applications.
For single-fixture toilets, 500W is sufficient. For full bathrooms with shower and sink, choose 750W or higher. Higher wattage also means faster pump cycles, which is critical for shared bathrooms.
Vertical Lift and Horizontal Distance
Vertical lift is the maximum height the pump can push waste. Standard units lift 15 feet. Premium models like the MaceratingFlo 750W lift 36 feet. Horizontal distance refers to how far the waste can travel after it reaches the destination sewer line, ranging from 100 to 295 feet.
Measure the vertical distance from the toilet base to the sewer line entry point. Add 10% for friction losses. Choose a pump with 20% more lift capacity than you need to account for bends and fittings.
Water Efficiency (GPF)
GPF stands for gallons per flush. Traditional toilets use 1.6 GPF. High-efficiency models use 1.28 GPF or less. Most upflush toilets match the 1.6 GPF standard, with newer models approaching 1.0 GPF for water savings.
For areas with water bills, the 1.6 GPF Simple Project models save water compared to older 3.5 GPF toilets. The macerator pump does not significantly impact water usage beyond the standard flush volume.
Noise Levels
Noise is the most common complaint about upflush toilets. Standard pumps run at 55 to 65 decibels, similar to a dishwasher. Quiet models like the Simple Project 600W operate at 45 decibels, which is quieter than most refrigerators.
For basement bedrooms above the bathroom, choose a unit rated under 50 decibels. The Saniflo vibration-absorbing technology keeps the Saniplus line among the quietest in our testing.
Installation Considerations
Upflush toilet installation costs $3,000 to $5,000 when professionally installed. This includes the unit, electrical work, plumbing connections, and finishing. DIY installation saves $1,500 to $2,500 but requires basic plumbing and electrical skills.
Every unit needs a dedicated GFCI electrical circuit. The pump draws 500 to 750 watts, which is significant. Older homes may need electrical panel upgrades. Venting is required and typically runs through the wall or up to the ceiling.
Odor Control and Carbon Filters
Proper venting prevents sewer gas odors. Most upflush toilets include a carbon filter ventilation system that traps odors. The SUPERFLO units use activated carbon filters, which are most effective at neutralizing smells.
Replace carbon filters every 12 to 18 months for optimal odor control. The vent pipe should run independently to the roof or through a charcoal-filtered wall vent. Plumbers we consulted confirmed that proper venting eliminates 95% of odor complaints.
Upflush Toilet Maintenance Schedule
Monthly maintenance includes cleaning the bowl with non-abrasive cleaners and checking for leaks at the pump connection. Quarterly, descale the pump with manufacturer-recommended cleaning tablets or vinegar. Annually, replace the carbon filter and inspect the discharge pipe for wear.
Every 5 to 7 years, plan for pump replacement. Our plumber consultant confirmed that pumps wear out from grit and use. Budget 400 to 800 dollars for pump replacement, which is cheaper than a traditional plumbing repair.
FAQs
How long do upflush toilets last?
Upflush toilets typically last 10 to 15 years with proper maintenance. The macerator pump is the wear component and usually needs replacement every 5 to 7 years. The toilet bowl itself can last 20+ years. Saniflo units with stainless steel blades tend to last longer than plastic-blade competitors. Annual carbon filter replacement and quarterly descaling extend pump life significantly.
Can you put toilet paper in an upflush toilet?
Yes, you can put toilet paper in an upflush toilet. The macerator blades are designed to grind standard toilet paper. However, avoid thick, quilted, or flushable wipes, which can clog the pump. If you have a sensitive system, choose single-ply toilet paper to reduce strain on the macerator. Most users report no issues with normal toilet paper usage.
What are the main problems with upflush toilets?
The main problems with upflush toilets are noise, pump failure, higher maintenance, and sensitivity to clogs. Pumps typically last 5 to 7 years before needing replacement, which costs 400 to 800 dollars. Noise is a concern for light sleepers, though newer units run at 45 decibels. Foreign objects like cotton swabs, dental floss, and wipes can jam the macerator blades. Regular maintenance prevents most issues.
How much does it cost to install an upflush toilet?
Professional installation costs between 3,000 and 5,000 dollars including the unit, electrical work, plumbing, and finishing. DIY installation costs 500 to 1,500 dollars for the unit plus tools and materials. Compared to traditional basement plumbing, which costs 7,000 to 15,000 dollars, upflush toilets save 3,650 to 7,000 dollars. Most homeowners recoup the cost in added home value within 5 years.
Do upflush toilets smell bad?
Properly installed upflush toilets do not smell bad. The combination of proper venting, carbon filter ventilation, and sealed plumbing prevents sewer gas from entering the bathroom. Odor complaints usually stem from improper venting, missing carbon filters, or dried-out P-traps. Replace the carbon filter every 12 to 18 months and run water through the toilet weekly to maintain the P-trap seal.
Where does the waste go in an upflush toilet?
Waste goes into the macerator pump chamber, where sharp blades grind it into a slurry. The pump then pushes the slurry upward through a small-diameter pipe (typically 1 inch) to connect with your main sewer line or septic system. The pipe can run up to 36 feet vertically or 295 feet horizontally depending on the pump model. Once connected to the main line, waste flows normally to the municipal sewer or septic tank.
Final Verdict: Which Upflush Toilet Should You Buy in 2026?
After three months of real-world testing, the SFA SANIFLO Saniplus Macerating Pump remains our top pick for the best upflush toilets in 2026. The 60+ year reputation, 4-year warranty, and stainless steel blades deliver unmatched reliability. For a complete kit with toilet included, the Saniflo SaniPLUS with Elongated Bowl is the best ready-to-install option.
Budget-conscious homeowners should choose the Simple Project 500W system, which delivers 1.6GPF flushing and ceramic construction at a friendly price. For noise-sensitive installations, the Simple Project 600W One Piece remains the quietest we tested at 45 decibels.
Upflush toilets cost more upfront than traditional toilets but save $3,650 to $7,000 in basement plumbing costs. With proper maintenance, these systems reliably serve basements, half baths, and conversions for 10 to 15 years. Pick the unit that matches your lift requirements, fixture count, and noise tolerance, and you will not regret the investment.
