INSTALLING PIPING IN WELL
Shallow Well Application
Where suction lift is less than 25'
1. On single pipe installations (Fig. 1) attach foot valve to the end of the suction pipe and set in the well, making certain the valve is below the
water level. The foot valve should at least five (5) feet from the bottom of the well to prevent sand from being drawn into the system.
2. When connecting a drive point (Fig. 2) a check valve must be used in the
suction line in place of a foot valve. For easy priming connect the check valve
as close to the well as possible.
3. All piping from the well to the pump should slope slightly upward with no
sagging. Support suction pipe between water source and pump. Unions
in the suction line near the pump and well will aid in servicing. Be sure to
leave enough room so that wrenches can be used easily.

Deep Well (Double Pipe System)
Where water level is greater than 25 feet and inside diameter of well is 4" or larger
1. Attach the foot valve to the ejector using a galvanized steel or plastic nipple. Add enough
1 in. pressure pipe and 1-1/4 in suction pipe to submerge ejector 10 to 15’ below pumping
water level, making certain foot valve is at least five (5) feet from bottom of well. If
pressure pipe and suction pipe of the same diameter are used, be sure to identify them
clearly so that they will be connected to the proper tappings of the pump.
If a known well leak exists, replace nipple with 21 feet of 1” tail pipe between the ejector
and the foot valve. This will provide a continuous source of water for the pumping system.
2. Check pipe and foot valve for leaks by filling pipes
with water. A continuous loss of water
indicates a leak in the piping, foot valve or unions, and must be corrected.
3. If no leaks are found, proceed to WELL TO PUMP CONNECTION (SUCTION PIPE). For
long offset distances, see chart below for proper pipe size.
4. All piping from the well to the pump should slope slightly upward with no sagging. Support
suction pipe between water source and pump. Unions in the suction line near the pump and
well will aid in servicing. Be sure to leave enough room so that wrenches can be used easily.
