Water Pumps

This is a direct suction pump that starts operating suction once detecting a drop in water pressure upon usage. To minimize noise, it is recommended to install rubber cushion at the base of the pump.

1. Water-logged pressure tank.
2. Improper air pre-charge in an internal-bladder type pressure tank (too little).
3. Very rapid cycling can be due to a clogged water filter or any blockage at the outlet side of the pump.
4. Piping is too narrow and too long, leading to uneven distribution of pressure, causing air lock. Old piping should be replaced and number of outlet taps should be as specified.

1. Slow water leak such as a running toilet.
2. Leaky check valve or foot valve in the well piping system causing loss of prime in pump & well piping.
3. Debris-clogged pressure sensor port on the pressure switch or its mounting / sensor tubing can cause delayed sensing of a drop or rise in water pressure.
4. Piping is too narrow and too long, leading to uneven distribution of pressure, causing air lock. Old piping should be replaced and number of outlet taps should be as specified.

1. Check that electrical power is turned on and being delivered to the pump control switch and to the pump.
2. Check the water pressure at the tank & by using an independent pressure gauge (in case the tank gauge is stuck).
3. Check water pressure from incoming water flowing into the pump. Install the check spring to the checking valve to prevent strong pressure to the pump.
4. If incoming water pressure is too strong, install a water tank beside the pump.

1. Pump capacity too high for water outlet.
2. Clogged water filter or closed or mostly-closed valve at pump outlet.
3. Piping is too narrow and too long, leading to uneven distribution of pressure, causing air lock. Old piping should be replaced and number of outlet taps should be as specified.

The pump and the tank should be installed after the supply tank. This is to prevent absense of water suction and temperature rise which causes the deformities.

1. Water is running.
2. A water pipe or well piping is leaking.
3. The pump is damaged and cannot reach cut-off pressure.
4. The pressure control switch cut-off is set too high.
5. Water level in the well is too low and a tailpiece is recycling water through the pump system.
6. Pump has lost prime due to leak in well piping or a failed check valve or foot valve.
7. If you have tampered with the pressure control switch settings they may be adjusted out of range.
