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 protec-
tion 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.
Pump body may explode if used as
booster pump. DO NOT use in booster application.
Motor normally operates at high tempera-
ture 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.

tions of pipe as needed, using Teflon tape on
male threads (use 1-1/2" pipe for suction pipe).
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 (pump-
ing water level). Your well driller can furnish this
