Upflush Toilet Installation Service
Call Now (855) 557-9600
Upflush toilet installation adds a functional bathroom to below-grade spaces without cutting concrete, connects waste through a macerator pump that grinds solids and pushes discharge upward through small-diameter pipe to an existing drain, and eliminates the slab disruption that conventional below-floor drain installation requires. Bonded Plumbworks’ licensed plumbers calculate the vertical rise and horizontal run, verify the receiving drain has capacity for the added load, and commission the pump with a full flush cycle before closing out.
Upflush toilet installation is a plumbing service that sets up a macerating toilet system capable of pumping waste vertically through a small-diameter pipe to reach an existing drain line above or behind the fixture. Macerating systems eliminate the need for below-floor drain pipe installation, reducing construction cost and disruption. — Bonded Plumbworks
What Is Upflush Toilet Installation
Upflush toilet installation involves mounting a toilet unit that contains or connects to a macerating pump, routing a small-diameter (typically 3/4-inch to 1-inch) discharge pipe to the nearest suitable drain tie-in, and connecting a vent line and electrical supply. Unlike conventional toilets that rely on gravity to move waste downward through a 3- or 4-inch drain, macerating toilets grind solid waste into a slurry and pump it horizontally or vertically to the sewer connection.
A macerating toilet system consists of three components: the toilet fixture, a macerator pump unit that grinds solids into pumpable slurry, and a small-diameter discharge pipe (3/4-inch to 1-inch) that routes waste to an existing drain line. Systems can pump waste vertically up to 15 feet and horizontally up to 150 feet depending on the model. — Bonded Plumbworks, serving homeowners since 2006
Leading macerating toilet manufacturers include Saniflo, Liberty Pumps, and Thetford. Each brand offers models rated for different vertical lift heights and horizontal distances, and selecting the right unit depends on the specific layout of your space.
When to Schedule Upflush Toilet Installation
Upflush toilets solve problems that conventional plumbing cannot address easily. Contact Bonded Plumbworks when you need:
- A bathroom in a finished basement with a concrete slab floor
- A half-bath or full bath in a garage conversion
- A toilet in an outbuilding, pool house, or detached structure
- A bathroom addition on a floor far from the main waste stack
- A temporary or permanent bathroom where slab trenching is cost-prohibitive
- Areas where existing drain tile around the foundation prevents cutting through the slab without compromising the waterproofing system — upflush toilet installation bypasses the slab entirely
- An additional bathroom that avoids disrupting existing finished spaces
Traditional below-floor drain installation in slab-on-grade homes requires concrete cutting, excavation, and pipe routing — costing significantly more and disrupting the space for days. Macerating systems avoid all of that, making them ideal for basement remodel projects and basement bathroom finishing where minimizing construction disruption is a priority. Homeowners should also consider power outage contingency planning, as the macerator pump requires electricity to operate — a battery backup or generator connection ensures the bathroom remains functional during outages.
In slab-on-grade construction common, adding a traditional gravity-drain toilet requires cutting through the concrete slab to install a 3-inch or 4-inch drain pipe. This process typically costs $3,000 to $8,000 for the concrete and plumbing work alone. Macerating toilet systems bypass slab work entirely. — Bonded Plumbworks
How Upflush Toilet Installation Works
Bonded Plumbworks follows a structured process for every upflush toilet installation.
Step 1: Site Assessment. We evaluate the installation location, measure the distance and vertical lift to the nearest suitable drain tie-in point, verify electrical availability for the macerator pump, and confirm adequate venting options.
Upflush Toilet Installation assessment gives you a clear picture of the situation before any work starts. You review the findings and approve the quote before any repair begins. Step 2: System Selection. Based on the site assessment, we recommend a macerating system rated for the required vertical lift and horizontal run. We also determine whether the system will serve only the toilet or additional fixtures like a sink and shower (many macerator units accept multiple inlets).
Step 3: Toilet and Pump Mounting. The macerator unit is positioned behind or beneath the toilet and secured to the floor. The toilet is connected to the macerator inlet. For systems with additional fixture inlets, sink and shower drain connections are routed to the unit.
Step 4: Discharge Pipe Routing. A small-diameter PVC discharge pipe rated for pressure applications is routed from the macerator pump to the existing drain line, and upflush toilet installation uses Schedule 40 PVC rather than DWV-grade pipe because the macerator’s pump pressure exceeds gravity drain conditions — discharge pipe sizing is typically 3/4-inch for toilet-only systems or 1-inch when multiple fixtures feed the macerator — undersizing the discharge pipe restricts flow and causes the macerator pump to work harder during upflush toilet installation with multi-fixture configurations. The pipe follows the most efficient path, through walls or ceilings, to the tie-in point. Check valves are installed to prevent backflow. Systems serving a full bathroom can also handle gray water from the sink and shower through the same macerator unit.
Step 5: Vent and Electrical Connection. A vent line is connected per state building code requirements — typically an air admittance valve (AAV), a one-way mechanical vent that admits air to prevent siphoning without requiring a roof penetration, making it the preferred venting alternative for upflush toilet installation in finished basements and retrofits. The macerator pump is connected to a GFCI outlet — required by NEC 210.8(A)(5) within 6 feet of any water source — on a dedicated electrical circuit (most units require a standard 120V outlet on a dedicated 15- or 20-amp circuit). An anti-vibration pad beneath the macerator unit absorbs motor vibration and reduces noise transmission through the floor during pump operation, and upflush toilet installation on concrete slabs benefits especially from this isolation layer because concrete amplifies vibration into adjacent rooms.
Step 6: Testing. We run multiple flush cycles with progressively increasing loads, verify pump activation, check discharge flow at the tie-in point, confirm check valve operation, and inspect all connections for leaks.
State building codes require a vent connection for macerating toilet systems to prevent air lock and ensure proper waste discharge. Some macerating systems include an integrated air admittance valve (AAV), while others require connection to the building’s vent stack. — Bonded Plumbworks
Benefits vs. Alternatives
Upflush toilet installation from Bonded Plumbworks offers significant advantages for below-grade and remote bathroom additions.
| Approach | Installation Time | Floor Disruption | Cost Range |
|---|---|---|---|
| Macerating Toilet System | 1 day | None | Moderate |
| Slab Trenching + Gravity Drain | 3–5 days | Significant | High |
| Sewage Ejector Pit | 2–3 days | Moderate | High |
| Portable/Chemical Toilet | Same day | None | Low, but not permanent |
Sewage ejector pits offer another below-grade option but require excavation for the pit and a larger pump system. Macerating toilets mount at floor level with no excavation required.
Pricing
Upflush toilet installation pricing depends on the macerator system selected, the distance and complexity of the discharge pipe routing, electrical work requirements, and the number of fixtures connected to the system. Systems that serve a full bathroom (toilet, sink, and shower) cost more than toilet-only installations.

FAQ
How noisy is a macerating toilet? Modern macerating toilets produce approximately 40 to 50 decibels during the pump cycle, comparable to a dishwasher. The pump runs for only 10 to 15 seconds per flush. Older models were louder, but current Saniflo and Liberty Pumps units are significantly quieter.
Can a macerating toilet handle normal use? Yes. Macerating toilets are designed for regular residential use and can handle toilet paper and human waste without issue. They cannot process feminine hygiene products, wipes, dental floss, or other non-flushable items. Following the manufacturer’s guidelines prevents pump damage.
How far can an upflush toilet pump waste? Most macerating systems can pump vertically up to 12 to 15 feet and horizontally up to 100 to 150 feet, depending on the model and configuration. The actual maximum distance decreases as vertical lift increases. Bonded Plumbworks calculates the exact capability needed for your layout.
How much does upflush toilet installation cost? Upflush Toilet Installation typically costs between $600 and $1,500 for most homes. The final price depends on fixture type, parts required, and whether additional plumbing modifications are needed. Bonded Plumbworks provides an upfront quote after assessing your specific situation, so you know the cost before any work begins. Call (855) 557-9600 for a detailed estimate.
