[ + ] Installation Options
Option 1: Pump and Plumbing Behind Wall
For this methond, you will need a 3" rigid pipe and a 3" pipe coupler (not included) to achieve proper drainage slope. Distance between toilet outlet and pump inlet can not exceed 36". Allow additional space for maintenance purposes. 
Lift Assure Plumbing Option 1

Option 2: Exposed Pump with Plumbing In Wall
The pump is placed in front of the wall with the plumbing within the wall. Allow additional space for maintenance access purposes.

Option 3: Pump and Plumbing Exposed
Both the pump and the plumbing are in front of the wall. Allow additional space for maintenance access purposes.

Lift Assure Installation Option 3
[ + ] Toilet and Pump Installation

Check the following before starting installation:

  • Floor site should be finished and level.
  • Check for clearance of doors and cabinets as well as any shower enclosure.
  • Ensure that all plumbing and electrical fixtures do not interfere with placement of bathroom fixtures.
  • Rough plumbing and electrical are completed to code.
  • Placement of the electrical outlet must also meet local code. It is recommended to leave a 40” distance from bathtub/shower and within 6’ of the pump.
  • Drill the floor holes for toilet placement. If installing on a concrete floor, install anchors, but DO NOT permanently secure fixtures until instructed.

Concrete Floor Installation:

Using Anchors:
Drill 2 holes using a 1/2” masonry drill bit; then insert the provided screws.

Wood Floor Installation:

Using Only Screws:
Drill 2 pilot holes using a 1/4” drill bit.

IMPORTANT: Do not plug the macerator into an extension cord, for this is a safety hazard and can cause injury.

Caution: To permit proper drainage it is essential to elevate the shower/tub drain to a minimum of 9” above the finished floor of the installed pump. If necessary, remember to adjust the height of the shower/tub drain upwards to allow proper grade for the plumbing connection to the pump. It is important to plan accordingly.

[ + ] Installation

Part 1:

Macerator Installation

Vent Line Shower/Tub/Sink Discharge

The macerating unit must be vented. It has 2 inlets on the top of the cover: a 1 1/2” cap and a hole of smaller diameter.

The unit must be connected to a vent system according to the plumbing codes.

Put the waste inlet (provided) on the cap and clamp it down.

After, connect the vent pipe. All fixtures connected to the system must also be vented.

To connect to the side entries of the case, use the side connector.

Secure with clamps.

Plug the unused inlet with blanking plug after greasing the joint.

Ensure when connecting a shower to the macerating unit that the underside of the shower tray is raised at least 9 inches from the floor.

These macerating units have an elbow and a bushing.
Simply cut off the appropriate portion of the bushing in order to fit it to the discharge pipe.

Use ridged wall pipe, not flexible pipe or hose, as flexible pipe may distort over time. Use 3/4” or 1” discharge pipe.
Install a “full-part” ball or gate valve and a union in the discharge pipe in order to facilitate the removal of the macerating unit. Place the union or hose connector followed by the valve of the lower portion of the discharge pipe. If you need the unit to pump both vertically and horizontally, remember that 3 feet of vertical lift is equal to 30 feet of horizontal run.

Discharge pipe work can be made from 3/4” diameter Type M Copper, CPVC, or PVC. Use long turn bends, not elbows. The connection to the soil-stack or sewer pipe must be made with an approved wye fitting. If you are not comfortable with this procedure, have a plumbing contractor install for you.

Part 2: Connection to Bath/Shower/Sink

Before making any connections, make sure there is proper slope of all horizontal runs.

Bath and Shower Attachment:

  1. For proper draining it is essential to elevate the shower/tub drain to a minimum of 9” above the finished floor of the installed pump. If applicable, adjust the height of the shower/tub drain upwards to allow proper grade for the plumbing connection to the pump.
  2. If bathtub is connected, the 2” connection can be reduced to 1-1/2” with adequate slope into the pump.
  3. Measure rigid pipe from 2” pump inlet to shower/bath drain.
  4. Cut pipe to fit, then connect shower/tub to 2” inlet with proper slope.

Sink Attachment:

  1. Measure rigid pipe from sink drain to 1-1/2” pump inlet.
  2. Cut pipe to fit.

Vent to Vent Stack Attachment:

IMPORTANT: Do not use one-way air admittance valves (or cheater vents). Macerating pumps need two-way air movement. They must also be vented to the outdoors.

  1. Measure rigid pipe from vent on pump to vent connection. Either to new or existing vent stack.
  2. Connect rigid pipe to main vent stack of house or directly outdoors.

Discharge Line Attachment:

IMPORTANT: The pump discharge outlet has a built-in check valve. Do not install an additional check valve as this may cause the pump to malfunction.

  1. Install 1-1/4” ball valve approximately 6” from pump discharge outlet.
  2. Install 1-1/4” plumbing line to the home’s main waste line. There must be at least 3 feet of run from the pump before connecting to the main waste line.
Part 3: Connecting Toilet and Pump

The following instructions apply for Option 1 seen on page 6.
NOTE: Make sure the floor holes are drilled before you begin the following steps.

  1. Drill a hole in the wall sized to accommodate pipe slope.
  2. Position clamp onto the toilet outlet. Hint: Apply soapy water to lubricate for easier clamp application; make sure you use non-petroleum-based products only!
  3. Install the pan gasket in place making sure it covers at least 1-1/2” of the toilet outlet.
  4. Cut a 3” rigid pipe to fit; do not let it exceed 36”.
  5. Insert the pipe through the wall, connecting one end to the toilet outlet and the other to the macerator.
The pan gasket must cover at least 1-1/2” of the pipe. The side cover of the macerator must also cover at least 1-1/2” of the pipe.

The following instructions apply for Option 2 and 3 on page 6

  1. Position clamp onto the discharge outlet on the rear side of the toilet. If necessary, apply soapy water to lubricate the clamp for easy application.
  2. Position the side cover of the macerator onto the toilet outlet and tighten, making sure it covers at least 1-1/2” of the outlet.

Part 4: Toilet Assembly

Note: Assemble water tank as explained in the supplied instruction sheet, before proceeding with the following steps.

  1. Check to make sure toilet is leveled before securing the toilet to the floor.
  2. Install water tank in place. It is recommended to apply caulk around the base of the opening.
  3. Secure the water tank with the provided nuts and bolts.
  4. Verify that proper placement of the hose is established.
  5. Install the seat cover bolts into the proper position, and secure by hand-tightening.

Part 5: Testing the System

  1. Finish connecting all fittings and fixtures
  2. Open the water supple valve to toilet and/or fixtures.
  3. Check for leaks and correct as needed.
  4. Plug the pump into wall outlet.
  5. Flush toilet.
  6. Double check for leaks; tighten and adjust clams and connections if necessary.
[ + ] System Operation

What To Expect
This toilet operates on a different principle than a typical siphon toilet, resulting in a different sound and flush action. When activated, the pump pulses a few times.

Use only non-abrasive, non-petroleum products to clean the pump.

Prime the Pump
If pump initially runs for more than 10 seconds, prime the pump as follows:
a. Unplug cord from wall outlet.
b. Wait 15 seconds. Plug cord back into wall outlet.
c. Flush again. If pump runs more than 10 seconds, repeats steps a-c.

If the Lift Assure system is exposed to freezing temperatures, please make sure that all fixtures, inlet, and discharge lines are winterized using non-toxic propylene glycol (RV Marine AntiFreeze). Use sufficient quantity of antifreeze to ensure all pipes are protected.First, you must shut off the water supply. Flush toilet to empty the tank. Pour RV/Marine Antifreeze into toilet and all fixtures. Press manual switch to run antifreeze through system.

Cleaning Debris from Pump
While the Lift Assure does not need any maintenance under normal conditions, it is okay to clean out the macerating unit once a year. Do not use bleach. The macerating unit starts automatically once the toilet is flushed or the other bathroom appliance discharge and cease operation once the contents have finished pumping.
