INSTALLATION
NOTICE:
Install pump on a hard, level surface (cement, asphalt, etc.). Never place
pump directly on earth, clay or gravel surfaces.
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.
If using as a sump pump, a check valve is recommended.
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.
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 discharge
line), size pipe as follows:
A Pipe Size Of:
Will Handle a Flow Rate Of:
1-1/2” (3.8 cm)
12 GPM (45 LPM)
2” (5.1 cm)
21 GPM (80 LPM)
2-1/2” (6.3 cm)
30 GPM (114 LPM)
3” (7.6 cm)
48 GPM (182 LPM)
Use a 2” (5.1 cm) swing check valve in pump discharge to prevent backflow of liquid
into sump basin. Check valve should be a free flow valve that will easily pass solids.
NOTICE:
For best performance of check valve when handling solids, do not install it
with the discharge pipe angled more than 45° above the horizontal. Do not install
check valve in a vertical position as solids may settle in valve and prevent the check
valve from opening on startup.
Drill a 3/16” (4.7mm) hole in discharge pipe about 1"-2” (2.5 - 5.1cm) above pump
discharge connection (but below check valve) to prevent airlocking the pump.
