First are you on well water or city water? If you are on municipal water- is the water filling line before the pressure regulator or after it?
I am on well water. the hook up is through the hot water heater and is therefore softened water.
Are you sure the fill valve is off-what I mean is, is a ball valve used to shut it off? or a globe valve? If the globe valve has a little bit of dirt on the seat it will not shut off.
I checked the valve and I believe the ball wasn't shutting...I have adjusted it and it still takes awhile to stop draining, but I believe that is the pressure left as you said.
Thanks for the quick response. This is my first experience with all this and I appreciate all the help everyone offers on this site. I would have made several mistakes if it weren't for spending hours reading through all the info on this site.
Thanks again.
