Pressure tank psi too high.
They usually run on a 30 50 psi cycle or a 40.
You ll need to check what the pressure on your hot water heater s temperature pressure valve is but it s probably also fine.
When your water pressure is too high.
The ideal pressure for the health of your plumbing system and appliances is between 40 and 60 psi and building codes in most areas specify that water pressure be under 80.
Uses troubleshooting i was reading about tank pressure problems and short cycling water pumps we have a amtrol well x trol wx 250 44 gallon pressure tank which is about 14 years old.
If yours measures over 80 psi on the gauge it is definitely time to lower the pressure.
I have a 20 gallon pressure tank that is a year old in fact the entire well was drilled exactly a year ago.
This means that the pump shuts off at the higher 50 psi and turns back on to fill the pressure tank at 30 psi.
Step 2 find the water pump s gallon per minute gpm capacity as stated in the manufacturers specifications.
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.
White circular gauge about an 1 1 2 in diameter near the bottom of the tank.
You will need to check your tank but most pressure tanks are good to 100 or 125 psi the ones in the upper chart are only 75 though so that s probably not the limiting factor.
You should check the tank pressure periodically and bleed some air out of it if the pressure is more than 2 psi above the pump s cut in pressure.
Anything over 80 psi and you re in the danger zone.
This pressure represents the tank empty of any water as when there is water within the tank the pressure will increase.

It s also possible that you have a faulty expansion tank on your water heater.

As an example a 1 horsepower hp pump is rated for 20 gpm but is only able to deliver 10 gpm of water from the well source.
The opposite condition the pressure is too high could be hazardous.

40 60 pressure switch on our well.
Ideally you want your water pressure to be between 40 and 60 psi.
The schrader valve could rupture or the pump could cycle erratically.
If your well tank is on a 40 60 pressure switch your pressure setting should be 38 psi.
Well pressure tank psi set too high question.
The cut on pressure for the well pump is 30 psi so the pressure of the tank should have a pressure of 28 psi.
