I hope this is a "I'm such a dummy" question...getting ready for a shakedown trip in our new to us 21' 79 Barth...filled the fresh water tank...opened the on/off valve...turned on the near new pump...pump ran and ran and ran...never shutting off...faucets only had a tricle of water...Barth is on a hill (San Francisco) with the pump and water tank on the downhill...I know someone on this great site can help...thanks...joe...

You have an air leaks somewhere. Assuming there isn't a water leak and there is an inch of water on the floor. 1st thing to check is the valve city water inlet valve. There is a little spring loaded valve in there. Of course if you have a cap on it like we all should then that is not the problem. Now there is probably a valve somewhere to turn off the water coming in from the city and filling your tank make sure that is closed.

Thanks Dave...I'll check this out first thing in the morning...by the way the new site is fantastic...joe...

Capped the city water inlet valve...problem solved...good water pressure...thanks for the help...joe...
