    Do you have an old Moen valve from the 70's or 80's? I love updating those old valves in the Seattle area. Replacing the cartridge makes them a new faucet, smooth and quiet.

    Moen TL473 trim fits the old Moen roughs. The T473 has the crystal knob, the TL473 is the lever.
    Or for just the handle and plate, T470 crystal knob and TL470 with lever.

    Theses came with the 1200 cartridge, and will accept both the 1200 and the 1225.

    Replace the cartridge while you are at it.
