Piping in the Well

INSTALLATION

For a pump at sea level mounted directly over the well, be sure the total lift from the pumping water level to the pump does not exceed 20 feet. This will be less ff the pump is off- set from the well.

The Shallow Well Water System can be installed on a dug well, drilled well or with a driven point. In a dug or cased

well, a foot valve and strainer should be installed for easy priming. It should be installed five to ten feet below the low- est level to which the water will drop while the pump is op-

erating (pumping water level). To keep sediment from clogging the strainer, be sure it is five to ten feet above the

bottom of the well. Before installing the foot valve, make sure that it works freely.

When using a foot valve, a priming tee and plug as shown in Figure l, are recommended.

The maximum lift of any pump decreases at the rate of about 1" less lift for every 1,000 feet of elevation above sea level.

For example, at Denver, Colorado (Elev. 5,000') the pump

loses five feet of lift. The maximum depth from which it

would pump water would therefore be 15 feet.

NOTICE: Use Teflon tape supplied with the pump or Plasto-

Joint Stik' for making all pipe-thread connections to the

pump itself. To avoid stress-cracking, do not use pipe joint

compot_nds on the pump.

1.Wrap male pipe threads being attached to pump with one or two layers of Teflon tape. Cover entire threaded portion of pipe.

2.Do not overtighten threaded fittings in the plastic pump. Be sure you do not try to tighten joint past thread stop in pump port!

3.If leaks occur, remove fittings, clean offold tape, rewrap with two to three layers of tape and remake the con-

nection. If joint still leaks, replace the fittings (fittings may be undersized).

4.Be sure to support all piping corlnected to.,,th.€ System.

Horizontal Piping from Well to Pump

When the pump is offset more than 25 feet from the well,

horizontal suction pipe size should be increased to reduce friction losses. Never install a suction pipe that is smaller than the suction tapping of the pump.
