How much air pressure should be in a water bladder tank?
This differs depending on your tank’s pressure settings. Most well tanks come set at 30/50. The cut-on pressure for the well pump is 30 psi, so the pressure of the tank should have a pressure of 28 psi. If your well tank is on a 40/60 pressure switch, your pressure setting should be 38 psi.
What happens if bladder tank pressure is too low?
Check the air charge inside the bladder pressure tank Loss of air inside the tank will result in over-expansion of the bladder, leading to premature bladder failure. Loss of air will lead to excessive pump cycling, which may shorten the life of the well pump motor.
What to do if your bladder pressure tank is not working?
If it appears that a bladder tank is not operating correctly, check the tank’s air charge: Disconnect electrical power to the pump. Drain the tank by opening the closest faucet. Check the tank’s pressure by placing an air pressure gauge on the air charging valve on the top of the tank.
How is the bladder in a well pressure tank read?
Bladder tanks have two separate sections of the tank separated by the rubber bladder. The air section should be pressurized when there is no pressure on the water side of the system to 2-psi less than the pressure where the well pump turns on, if the system has pressure the tank will read only the system pressure and not the air pre-charge.
How can I check the pressure of my bladder?
Check the tank’s pressure by placing an air pressure gauge on the air charging valve on the top of the tank. Add air if the pressure is more than 2 psi below the pump cut-in pressure. Use caution when using an air compressor or air pump.
What to do if your water pressure tank is low?
Turn the power to the well off, drain all water from the tank, and then check the air in the bladder. It should be 2 psi below the cut-in pressure of the pressure switch (38 psi for a 40/60 switch). If it is very low, and I’m sure it will be, you can add air to it to try and get by for a while but you are only delaying the inevitable.

Why do you need air in a bladderless water tank?
Bladderless water pressure tanks, because the air charge and water are in the same container, can lose their air charge over time (air is absorbed into the water) and may need air added. See WATER TANK AIR, HOW TO ADD for details.
