Customer stated: they had no cold water in the basement. Tech notes: called out today to look at a basement with no cold water. While on site I found the basement shower was getting no cold water. I took the cartridge out and cleaned it along w8th where the cartridge sits. I tried putting the faucet back to get her and testing to still not get any cold water. Resolution: shower valve needs replace in order to get cold water. Job status not complete need to with return 2 handle shower valve. Dwellborn 07/31/24 Replaced shower valve and tested. Shower has proper pressure on hot and cold water. Job is completed
