    Well 20-20 hind-sight I would have had the mixing valve replaced when I redid the shower
    But it was not leaking at the time - 2004/5
    A new Moen cartridge a year later stopped a small drip (2005/6 ?)
    It started dripping again - off & on, now its pretty steady

    I do have a whole house filter to prevent sediment thru the lines
    I should have had the plumbing reworked & reversed the tub
    The opposite wall is a closet - plumbing is on an outswide wall
    Maybe in another 5 years I'll redo the bath again & have a plumber reverse the pipes/drain at that time :(

    So I need a new mixing valve & really don't want a low grade model from a big box store
    So what's a good brand to buy



    Bath was redone, cement board & tile
    The surround was in rough shape & leaking when we moved in
    So I didn't want to let water damage continue
    It wasn't as bad as my last house, old pic from before renovation:

    If you bought the cartridge at Low*s just go get another and return that one...it should have lasted longer than that....

    I have no faith that the valve has not been worn out
    I put the whole house filter on after we bought the house
    Almost every other fixture in the house has been replaced

    As a test I shut off the HW feed to the shower
    The leak stopped
    So not only a water waste, but am energy loss too
    The old water heater rusted out shortly after we moved in
    So pretty sure rust went thru the piupes & messed up the valve
    Since then both toilets are new(er), bath & kitchen faucets too
    One toilet was getting sediment
