I found a post in this forum that appears to answer my question, but I wanted to start a new topic to get a better grasp of the big picture.
My p&t valve line goes up and out to the patio. There appears to be water there (maybe 8 to 10 oz) every morning (after showers?). Here's the post that leads me to believe its either build up or too much pressure.
So if it is too much pressure, here's my question; how much pressure should be coming in from the street? Its City water. Is this a measurable thing, for a non-plumber like myself? A way to test it?
We have a toilet that chronically runs for a second or two occasionally (I've replaced the entire tank kit by now) that also made me think I had too much pressure.
I'm familiar with the valve to limit the incoming pressure, but only in passing. I say hello. Its silent...
Any advice would be grratly appreciated. Even if its "Dude, call a plumber..." I can post pics and models #'s, but for now its more of a general, philosophical discussion.
