Water Pump Pressure Tank Settings

70 of the off pressure.

Water pump pressure tank settings. 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. Check pressure in the tank with your pressure gauge. Click to enlarge any image.

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. For example your pump builds up pressure and shuts off at 500kpa then the pressure drops and it turns on again at 200kpa. 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. The lower number is the turn on point for the tank to bring in more water and the higher number shuts the pump off.

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. Turn the pump off at the switch and shut any taps on your supply. 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 to be setting your air pressure at 350 kpa 500 x 0 7.

If your well tank is on a 40 60 pressure switch your pressure setting should be 38 psi. Locate the pressure switch limits which are located inside the pressure switch cover. Psi and 40 to 60 lbs psi. Water pump or well pump pressure control switch setting faqs.

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. A pressure tank for a well is a necessity for any home that uses well water. In a typical setup a shallow or deep well pump transfers groundwater to a holding tank. The cut on pressure for the well pump is 30 psi so the pressure of the tank should have a pressure of 28 psi.

The common settings are either 30 50 or 40 60. Water pumps use a pressure control that specifies the pump cut in turn on and cut out turn off water pressures. Release or add air as necessary to make the pressure 2 psi below the pressure switch pump cut in setting. 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. Pressure switch limits are different on different types of pressure tanks such as 20 to 40 lbs psi 30 to 50 lbs. Measure the bladder pressure of the tank by fitting a bicycle tire pressure gauge on the tank air valve. For example at 40 60 the pump will turn on when system pressure reaches 40 psi pounds per square inch and turn off when system pressure reaches 60 psi.
