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 mini- mum flow requirements (2 feet (.6 m) per second in dis- charge 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 (79 LPM)
2-1/2” (6.3 cm)	30 GPM (113 LPM)
3” (7.6 cm)	48 GPM (181 LPM)

NOTICE: Use Teflon™ tape on pipe connections. Do not use ordinary pipe joint compound on plastic pipe or pump. Pipe joint compound can attack plastics and dam- age pump.

3.To reduce motor noise and vibrations, a short length of rubber hose (1-5/8"(41mm) I.D., e.g. radiator hose) can be connected into discharge line near pump using suitable clamps.

4.If the pump discharge line is exposed to outside sub- freezing atmosphere, then the portion of line 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.

5.Install a 2” check valve in the horizontal portion of the discharge pipe. Make certain, the flow indicating arrow, points away from the pump. This check valve 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.

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” (2.5 - 5.1cm) above pump discharge connec- tion (but below check valve) to prevent airlocking the pump.

7.Insert the float switch piggy-back plug into a proper- ly grounded outlet and the pump plug into the piggy- back plug.

8.Check the installation by observing the pump opera- tion through one complete cycle. Make sure that no parts of the assembly interfere with the float switch.

Risk of flooding. May cause personal injury or property damage. Failure to make this operational check may lead to improper operation, premature fail- ure, and flooding.

ELECTRICAL

Hazardous voltage. Can shock, burn, or cause death. When installing, operating, or servicing this pump, follow safety instructions listed below.

1.DO NOT splice the electrical power cord.

2.DO NOT allow electrical cord plug to be submerged.

3.DO NOT use extension cords. They are a fire hazard and can reduce voltage sufficiently to prevent pump- ing and/or damage motor.

4.DO NOT handle or service pump while it is connected to power supply.

5.DO NOT remove grounding prong from plug or mod- ify plug.To protect against electrical shock, the power cord is a three-wire conductor and includes a

3-prong grounded plug. Plug pump into a 3-wire, grounded, grounding-type receptacle. Connect pump according to electrical codes that apply.
