Customer had a Delta Monitor shower valve with a tendency to tap every second when the lever was centered between hot and cold. Loud in the wall downstairs too. Replaced the cartridge and the noise cleared up. The old cartridge was a bear to remove for some reason. Lots of green discoloration in the barrel. Cleaned it up and slathered the body with plumbers grease before installing the new cartridge, blue body.
