Well Pump Pressure Tank Psi

Use a car tire pressure gauge to measure pressure.

Well pump pressure tank psi. Turn off the circuit dedicated to the well pump. If your well tank is on a 40 60 pressure switch your pressure setting should be 38 psi. The air fill valve is similar to the valves found on tires for adding air though the air fill valve on the tank is metal. The common settings are either 30 50 or 40 60.

To add air to a pressure tank you can use any source of compressed air a bicycle pump will do. Psi and 40 to 60 lbs psi. 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. Test the air fill valve with an air pressure gauge and see where your pressure lies.

Set your store to see local availability add to cart. When the pressure drops below the threshold of 40 psi also known as pump cut in pressure the pressure switch will signal the water pump to turn on. With the water pump turned on water is being pumped from the well and into the system gradually filling up the water tank once again. Check pressure in the tank with your pressure gauge.

The cut on pressure for the well pump is 30 psi so the pressure of the tank should have a pressure of 28 psi. You can charge the tank via the air valve using a car tire inflator a compressor or even a bike pump. Air can be added with a compressor or bicycle pump. 30 psi pre charged vertical pressure tank 145 psi model bl060762s4000000 179 00 179 00.

Release or add air as necessary to make the pressure 2 psi below the pressure switch pump cut in setting. In a well system with a bladder style pressure tank the well bladder pressure should be 2 psi lower than the cut in pressure for the well pump. For example if your well pump pressure control switch is set to cut in start pumping water from the well at 30 psi then set the pressure tank to 30 2 28 psi. Which is 20 psi.

For those who need to increase this number. See water tank air how to add for details. This pressure represents the tank empty of any water as when there is water within the tank the pressure will increase. Pressure switch limits are different on different types of pressure tanks such as 20 to 40 lbs psi 30 to 50 lbs.

The pressure tank sits adjacent to the well pump. The lower number is the turn on point for the tank to bring in more water and the higher number shuts the pump off. Servicing your pressure tank. 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.
