Installation

Before You Install Your Pump
NOTICE Well must not be more than 20' (6.1m) depth
to water.
Step 1. Long runs and many fittings increase friction
and reduce flow. Locate pump as close to well
as possible; use as few elbows and fittings as
possible. Be sure suction line is straight and
angles toward pump.
Step 2. Be sure well and pipe are clear of sand, dirt and
scale. Foreign matter will plug pump and void
warranty. Use new pipe for best results.
Step 3. Protect pump and all piping from freezing.
Freezing will split pipe, damage pump and void
warranty. Check locally for frost protection
requirements (usually pipe must be 12" (30.5cm)
below frost line and pump must be insulated).
Step 4. Be sure all pipes and foot valve are clean and in
good shape.
Step 5. No air pockets in suction pipe.
Step 6. No leaks in suction pipe. Use Teflon tape or
Plasto-Joint Stik to seal pipe joints.
Step 7. Unions installed near pump and well will aid in
servicing. Leave room to use wrenches.
Risk of explosion. Do not ground to a gas
supply line. Pump body may explode if used as booster
pump. DO NOT use in booster application.
Risk of burns. Motor normally operates
at high temperature and will be too hot to touch. It is
protected from heat damage during operation by an
automatic internal cutoff switch. Before handling pump
or motor, stop motor and allow it to cool for 20 minutes.

Cased Well/Dug Well Installation

Step 1. Inspect foot valve to be sure it works freely.
Inspect strainer to be sure it is clean and secure.
Step 2. Connect foot valve and strainer to first length
of suction pipe and lower pipe into well. Add
sections of pipe as needed, using Teflon tape on
male threads. Be sure all suction pipe is leakproof
or pump will lose prime and fail to pump. Install
foot valve 10 to 20 ft. (3 to 6 m) below lowest
level to which water will drop while pump is
operating (pumping water level). Your well driller
can furnish this information.
Step 3. To prevent sand and sediment from entering
pumping system, foot valve/strainer should be at
least 5 ft. (1.5 m) above bottom of well.
Step 4. When proper depth is reached, install sanitary
well seal over pipe and in well casing. Tighten
bolts to seal casing.
Step 5. When using foot valve, a priming tee and plug
are recommended. (Fig. 1).
