Delta tub faucet repair (2 handle)

[cedre]

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.

I replace the springs and seals for those, and sometimes the stems. A little bit of plumbers grease is good while you are at it.

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.
