What is this cap with a mesh screen?
I'm planning to install a pressure regulator underneath my house, and was crawling around inspecting the lines. I'm not a plumber, just a curious homeowner.
I believe this is attached to the hot water line as it runs adjacent to the water main. The crawl space is TIGHT, so I was not able crawl the lines all the way back to the hot water. It looks like it has a mesh screen on it. Is this an old pressure relief valve?
Other clues, the house was built in 1988 in a mountain town in California
