I am in the process of a shower remodel. The rough in valves have been installed with the gray test caps (delta Multichoice) and the system pressurized for 2 months.
Today I removed the caps to install plugs after the wife complained about getting slugs of cold water in the other bathroom. We have what looks to be heavy deposits or a reaction occurring in the valve body.
I’m trying to understand what’s going on. We don’t have a water softener, but haven’t noticed major issues with minerals. The old valve of 25 years didn’t have any issues. Water was likely being pushed back and forth across the valves due to pressure differences in the hot and cold side. Still, this seems excessive and has me concerned about issues, after cleaning, once the cartridges are installed.
I’m tearing them out to soak in vinegar. Surely there’s deposits where I can’t get with a rag.
Any experience, thoughts, or advice are appreciated. Is there something that could prevent this happening? I expect a few more months before the shower is done.
