Water Pump Pressure Tank Settings

Check pressure in the tank with your pressure gauge.

Water pump pressure tank settings. When the pressure in the system rises to the preset high setting the pump will turn off commonly known as the cut off pressure. Air can be added with a compressor or bicycle pump. Water pumps use a pressure control that specifies the pump cut in turn on and cut out turn off water pressures. The cut on pressure for the well pump is 30 psi so the pressure of the tank should have a pressure of 28 psi.

Psi and 40 to 60 lbs psi. In a typical setup a shallow or deep well pump transfers groundwater to a holding tank. A pressure tank for a well is a necessity for any home that uses well water. The lower number is the turn on point for the tank to bring in more water and the higher number shuts the pump off.

Water pump or well pump pressure control switch setting faqs. 70 of the off pressure. You want to be setting your air pressure at 350 kpa 500 x 0 7. Bleed air pressure out of the water tank or add air pressure into the water tank until the tank pressure is at the desired set pressure.

Turn the pump off at the switch and shut any taps on your supply. Locate the pressure switch limits which are located inside the pressure switch cover. For example your pump builds up pressure and shuts off at 500kpa then the pressure drops and it turns on again at 200kpa. From there the water passes into the pressure tank which is a second holding tank connected to a jet pump that keeps the water pressurized.

Pressure switch limits are different on different types of pressure tanks such as 20 to 40 lbs psi 30 to 50 lbs. Here we are discussing setting the water pressures at which a water pump will turn on to get more water and off to stop pumping water from the water source into the water tank.

You want the air in the tank to be approx. This article series describes how to adjust building water pressure by setting the water pump cut in and cut out pressure on the well water pump pressure control switch. We also provide a master index to this topic or you can try the page top or bottom search box as a quick way to find information you need. Most well tanks come set at 30 50.

Set the air pressure in the empty water tank to 2 psi below the well pump pressure switch cut in pressure. Let air out of the tank until this pressure is 2 to 4 psi below the cut in pressure for the. For example if you have a pressure switch setting of 30 50 psi you pressure measured at the top of the tank should read 28 psi. If your well tank is on a 40 60 pressure switch your pressure setting should be 38 psi.
