Hummelstown is in Dauphin County, Pennsylvania. Its ZIP code is 17036. We route shower valve replacement calls from 17036.
Cartridge or valve body
A shower that drips is usually the cartridge, which is a part. A shower that will not hold a temperature when a tap runs elsewhere is usually the valve, which is behind the wall.
Why the temperature swings
A valve that is not pressure-balanced sees the cold side drop when something else draws cold water, and the mix at the head follows it. That is the fault anti-scald valves were introduced to remove.
