Help. There is an annoying high pitched sound noise that comes out of our faucet in our front bathroom every time we take a shower or use water in our back bathroom. We read online it’s likely due to an old worn out washer or a loose one in the faucet somewhere..and the noise only occurs after water starts running through the pipes..but we can’t figure out what we need to change?!
Any idea on how much a plumber would charge to come fix this annoying issue? Or a rec for one that won’t rip me off?
