High pitched squeal in the pipes.
Looking for some basic location information for starters. When I am in the basement, and someone showers on the main floor, there is a high pitched squeal intermittently. I don't hear it IN the shower when it runs. I'm thinking it's in the utility room in the basement that I'm hearing it.
Any thoughts? I've seen some videos about replacing cartridges in the shower, but I swear I don't hear it IN the shower?
Thanks!
