    Hello!

    I have a delta 2 handle tub faucet that has a drip.
    I have replaced the hot/cold cartridges and the seats and stems behind them but the drip persists.
    I don't know why it should still be leaking.
    Any help would be appreciated.
    Will post pics of old cartridge below.

    thanks in advance.

    Thanks for replying Terry.
    I already have replaced the springs and seals but did not use plumbers grease.
    Would that be applied to back of cartridge (where it meets the seal) or around sides?

    I put a small bit on the rubber seals.

    Replace the stems. The new ones will have a stainless steel bottom. Those all plastic ones deform and do not seal to the rubber seats properly. I do not use grease on them.

    Terry, hj, thanks to you both for replying.
    hj I did replace the entire cartridge, I just didn't take a pic of it beforehand so I had to use the old one.
    It did have a metal plate on the bottom of it.
    And I also replaced the springs and seals.
