I've noticed recently water hammering in our upstairs 1 handle moen posi-temp pressure balanced shower when water is being used elsewhere in the house. This is a new occurrence. The Moen cartridge is 15 years old. Would simply replacing the cartridge fix this issue?
I should also add that the hammer only occurs in one position on the shower handle. If it starts to hammer and can make it stop by making the water hotter or colder and slowly bringing it back to the starting position.
