My shower has dripped since it was originally installed. I should have had it fixed back then, but now I have waited too late. In the meantime, the pressure was never that great and it seems like it has gotten really miserable lately. I know that new fixtures are low flow, but this is well below anything like that. I screwed the showerhead off to see if there was anything blocking that. There was some little pieces of rust or grit that you might typically find, but removing that didn’t do anything to improve the situation. Even with the showerhead off, there wasn’t much water coming out of the pipe.
The diverter in the main bathroom tub (switches between tub and shower) had failed and I wound up getting a new part from American Standard that fixed it. So I was thinking maybe I needed new parts for the shower as well and wanted to take apart the handles to see if I could figure out the problem. I was really hoping I wouldn’t have to do anything that would make me get into the wall because I don’t have an access panel for the shower. But if solder was blocking the pipes or grout had gotten in there, that might be the only way to fix it. So first I needed to turn the water off and the easiest way to do that for me is at the street. Once it was off I wanted to drain the water out of the shower so it wouldn’t get on me when I took the handles apart, so I opened up an outside spigot that is lower than the shower fixture (a bunch of water came out because the expansion tank pushes water out as the system pressure is relieved) and then went inside and turned the shower on. This allowed water to drain out of the outside spigot and suck in air through the shower.
