Connect your
water supply If using tap water:
Follow these instructions when supplying water from a pressurized source such
as city tap water:
Acquire a suitable garden hose and attach to the water supply:
1. Acquire a suitable garden hose:
a. The water supply garden hose must have an inside diameter of at least
5/8". If the hose is more than 100 ft. long, the diameter must be at least
3/4".
b. Always use a flexible rubber hose for your water supply. Do not use
rigid piping.
c. The use of a backflow preventer on the water supply hose is
recommended and may be required by local code.
2. Attach garden hose to water supply. Make sure it is not kinked.
Check adequacy of water supply:
1. Water supply should be standard tap water.
2. Make sure the water is clean. Debris can cause excess pump wear and
reduce performance.
3. Make sure the water supply is steady and capable of flowing at a rate 20%
over the rated flow of your pump. An insufficient water supply will damage
your pump. Use a stopwatch to time how long it takes to fill a 5 gallon
bucket with your garden hose. It should take less than 62 seconds.
Attach garden hose to the water inlet on the pump:
1. Attach garden hose to the water inlet on the pump for city tap water. See
"Machine Component Identification" section of this manual for location of
water inlet.
2. Confirm rubber washer and inlet screen are in the pump inlet before attaching
the garden hose.
3. OPEN the city tap water ball valve and CLOSE the tank feed ball valve, as
illustrated in the diagram below.
