The customer requested that we replace two Moen Temp shower cartridges at their home. In each unit, we turned off the water and removed the shower trim. We made a template for the new trim plate size and valve access. The old valves were removed and replaced with new ones. The supply of cold water has been restored. New tub spouts and trim were installed. The water heater was turned back on. The new units were put through their paces to ensure that they worked properly and had no leaks. At the current time, they are working effectively, and there are no leaks.
