I have a Delta single handle monitor pressure balanced bath valve-series 1400. The shower is leaking at the showerhead after I turn off the spigot. I was told I needed to replace the entire valve cartridge which was done. The shower still leaks. What could be the problem?
Also, if I shut off the hot water line, the leak stops. I do not get any water in the shower when I only have the cold water line open.Why is this?
Thank you :?
