Toilet and Pump Installation
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 ½” 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 ½” 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 ¼” ball valve approximately 6” from pump discharge outlet.
2. Install 1 ¼” 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.
