Well system water pressure falling off
Posted by Jeff Fowler on December 21, 2003 at 23:05:41:
I have spent a lot of time reading postings to this website, but have not found an exact answer for the problem I'm having. Hopefully someone can help.

Recently I replaced my old galvanized pressure tank with a new 82 gallon Flotec FP7120. I used the same pressure switch and left the settings as they were (48 on, 74 off). After calling Flotec customer service to verify, I added 6 psi to the empty but pre-charged tank to bring it up to 46 psi.

Before the old tank went bad, we had no problems with water pressure, but now experience the water pressure falling off to not much more than a trickle without recovering (or taking a very, very long time to recover).

The pump is not cycling frequently and is kicking on and off at the same settings is has since we moved in, in July.

Do I need to adjust the pressure settings with this new tank? Or does this have something to do with downdraw (which I don't really understand)? Is this a capacity problem?

Any thoughts or suggestions would be appreciated.
