I am wondering what could be causing my shower problem...I'm thinking possibly the mixing valve..but would like more input.
-When showering, water switches from hot to cold every few seconds throughout the shower.
-This does not occur with any other hot water faucet in the house
-Does not change with other faucet/toilet running/flushing
I live in a single story home with PVC pipe throughout- if there is other types of plumbing anywhere, I am not aware of it.
