recommended depth is 30" (76cm). Check local codes
for approved materials.
NOTICE: Pump should not be installed on clay, earth
or sand surfaces. Clean the area around the pump of
small stones and gravel which could clog the pump.
Keep the pump inlet screen clear.
2. Thread a 2" discharge pipe into the pump 2" NPT
discharge port. Be careful to avoid stripping or
crossing threads.
Piping – Effluent Applications
(3/4" or Less Solids)
Piping must be 1-1/2" minimum to carry volume of pump
discharge. Check local codes to determine if a check
valve is required in your system. In cold climates,
check valves are not used to prevent effluent from
freezing in piping.
Piping – Sewage Applications
(2" or Less Solids)
In any case, piping must not be smaller than pump
discharge.
When installed in a sewage system, pipe must be capable
of handling semi-solids of at least 2" (5.1 cm) diameter.
For parts or assistance, call Master Plumber Pump Customer Service at
The rate of flow in the discharge pipe must keep any
solids present in suspension in the fluid. To meet
minimum flow requirements (2 feet (.6 m) per second in
115V Properly
discharge line), size pipe as follows:

NOTICE: For best performance of check valve when
handling solids, do not install it with discharge angled
more than 45° above the horizontal. Do not install check
valve in a vertical position as solids may settle in valve
and prevent opening on startup.
6. Drill a 3/16" (4.7mm) hole in discharge pipe about 1"-2"

8. Check the installation by observing the pump
or property damage. Failure to make this operational
check may lead to improper operation, premature failure,
and flooding.

exposed must be installed so any water remaining in
pipe will drain to outfall by gravity. Failure to do this
can cause water trapped in discharge to freeze which
could result in damage to pump.

will keep the water from either running back into the
basin or into the area being pumped out when the
pump is not running. Check valve should be a free
flow valve that will easily pass solids.
