    I have an old Moentrol Legend set in my tub/shower, which works perfectly but the finish is gone.
    I'd like to replace the trim with the new Align trim. The Moentrol Align tub/shower trim works with "M-pact".
    My question is, will it work with my old Moentrol valve?
    I don't want to replace the valve, for obvious reasons.


    1 Check Stops Spring-driven gaskets at the valve inlets prevent high-pressure hot water from crossing the valve into a cold supply line or vice versa. (Hot water is at higher pressure in recirculation systems.) Screws in the stops shut off hot and cold lines at the shower for work on the valve cartridge.

    2 Pressure-Balancing Spool Hot and cold streams slide a graphite-composite piston in response to fluctuating hot and cold water pressure. In 0.1 seconds, the piston (inside the chrome sleeve) seals or opens inlets to maintain balanced pressure between the two flows, which are still unmixed. Lab tests to monitor internal movement show the piston constantly vibrating back and forth.

    3 Cartridge Pulling the shower handle slides the cartridge forward, opening two inlets to let hot and cold water enter and converge. Turning the handle opens one inlet as it closes the other, allowing users to adjust the temperature.

    4 Temperature Limit Stop Screwed into the cartridge's rod, this stop prevents a child from fully opening the valve to a scalding-hot setting

    As long as it is Moentrol, it will work with your valve.
