water pump (reverse flow?)


Here's my problem with my water pressure tank:

Takes too long to fill up or hit the desired pressure.
When it does reach the desired psi it goes back to zero in a couple of seconds (probably within 10 seconds).

I check the main waterline from the street to our house what I see is the needle of the water gauge going in one direction (meaning there is water entering our house) then the needle spins in the opposite direction. I assume that water is being sent back the main waterline?

My guess is that somewhere in our water pump a valve is faulty or something broke in our pump that it sends water back to the main water line?

HELP

Agree with above. If it has always worked in the past, and now is not working, perhaps a check valve in the system has failed, and you will need to replace it.

Water pressure is low, 1st floor bathroom only gets trickles.

Is there a check valve inside the pressure pump mechanism?

You should have a check valve directly after the house shut off valve. That should be the first valve after the meter. In many places it's required by law to be present and functioning.

They can get dirt in the seats and won't hold.

That kind of depends on your system. If you put up a picture of it, we could possibly point it out to you.
