Hi, when I turned on my shower this morning it made a very loud noise from the pipes that vibrated everything & was very loud. It almost sounded like a motor it was so loud. It doesn't happen when I'm running water out of the bottom faucet, but when I pull the mixer button up for the water to come out of the top fountain, the noise starts about 5 seconds after it starts coming out of the top faucet. Also it only happens when I have a mixture of cold & hot water on at the same time. :confused: Any help would be really appreciated! :D Thanks! My email is [email protected]

This is called "seat chatter" We need the brand name of the valve. One handle or two knobs? Regards, tom
