Take a look in the stem housing to see if the housing is scratched or there is some debris causing water to pass by the new stem.I recently tried to fix the drip on my Roman Tub. I replaced the inside of the Hot and Cold knobs with new Delta Stem Unit Assembly, Model # RP1740. After replacing the new with the old, the drip is still there. Any suggestions?
I believe it's plastic. I've attached a link to exactly what I bought below:Ron6519 said:Are these stems ceramic? Check for recesses in the perimeter.
The ones I buy come with protective plastic covers so the soft sealing edges don't get dinged in transit.
I see the black rubber gasket but don't see any springs. Is the spring below the gasket? Also, is it as easy as just popping out the gasket and replacing it?Ron6519 said:If you look look at the link you provided, there are parts youneed to change. The black rubber gaskets and the springs. That's what stops the leak, not the stem.
