It seems in home inspections things come in streaks. My streak of recent weeks was running into Moen single handle Posi-temp faucets that are not functioning correctly.

When testing the showers I could not get any hot water to come out of the faucet or showerhead.  I had hot water at the sink and other areas but not at the tub and shower.

Moen has a single-handled shower faucets that has an internal cartridge to regulate water flow and temperature. What can happen is this cartridge may become blocked, may not be functioning correctly, may have been installed incorrectly or the temperature limiter needs adjustment.

The correction of this is normally pretty simple. This may require that you remove the cartridge to make the proper repairs. These cartridges do have a special tool to remove the cartridge though.

Many Moen faucets have a temperature limiter installed on the valve stem that prevents the user from turning the handle too far to the hot side. To adjust this limiter you remove the handle.

With the handle off you see the plastic handle adapter, and the limiter, which consists of two plastic pieces.
