Pumping From Lakes, Streams, and Ponds
Locate pump as near as possible (vertically) to water source,
to keep suction lift (distance from water to pump) as low as
possible. Place pump on level support. Protect against ex-
cess moisture and flooding.
Long pipe runs and many fittings increase friction and re-
duce flow. Use the smallest possible number of fittings and
the shortest possible run for piping.
Support weight of pipe.
Be sure water is clear of debris which can clog pump, such
as sand, dirt, or scale. Be sure foot valve and hose are clean
and in good condition; scale or dirt in foot valve can cause
valve to leak. Valve leakage may cause pump to lose prime,
which can result in pump failure.
Piping
Both suction and discharge ports are tapped for 1" BSP
(British Standard Pipe) threads. If using hoses, use hose
adapters. When pumping from lakes, streams or ponds, use
reinforced hose supplied with pump. Ordinary garden hose
will collapse and cause pump failure. Keep strainer with foot
valve on end of suction hose. Inspect and clean strainer fre-
quently (Figure 1).
NOTICE: An air leak in suction pipe may draw air in al-
though no water leaks out. Make sure there are no air leaks
or air pockets in suction pipe.
115 volt, GFCI protected,
grounded outlet box.

Boosting City Water Pressure
Hazardous pressure. When using garden
hose as a discharge line, do not run pump with
hose outlet or nozzle closed. Hose or nozzle may burst from
excessive pressure. When using pump as a high-pressure
washer, use only reinforced high pressure hose or pipe for
discharge line. When using garden hose, install adapters to
pump suction and discharge. Suction hose will require two
female ends. Either use a standard washing machine supply
hose or modify a short piece of standard 3/4" garden hose
as a suction line (see Figures 2A and 2B).
Connect suction hose to faucet on outside of house (see
Figure 3, Page 4) and to pump suction. Use 3/4" standard
garden hose for discharge. Pump can supply up to 3 sprin-
klers (depending on GPM output of sprinklers).
Figure 2A – When using pump as a booster pump
with hose-connected suction and discharge,
install adapters to pump suction and discharge
ports.
Figure 2B – Connect pump to spigot for use
with sprinklers. Connect with adapters supplied
with pump.
