pressure tank question

[Ronnie C.]

I had my pressure tank replaced about 2 yrs ago and now when I turn the water on the pressure drops from 60 psi to 30 psi in about 7 seconds but water runs ok you can tell when switch kicks in with pressure. Not running out of water it just cycles every 7 seconds. My question is is it the switch ? or the bladder leaking in the tank ?
Its a well x troll tank and it is set 2 psi less than switch as recommended.
Any suggestions

Thanks Ron

yes you have a slow leak, this is not uncommon. I would just add more air to your tank, this should be checked every 6months or so. To properly do this you should have 0 press in your system before adding air to your bladder! good luck btw this may stir up some loose stuff in your sys., it may take a little time to clear, depending on your sys. setup.

Thanks f26tiger drained and released pressure and started from zero and it appears to be fine now.
Will just keep an eye on it and see how long it lasts. Thanks
