Constant Drip on Roman Tub
 

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?

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.

Thanks for the reply. Couldn't see any debris and don't see any scratches. Any other thoughts?

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 believe it's plastic. I've attached a link to exactly what I bought below:

A temp. fix if the noise is an issue is to tie a string to the spout and make it long enough to go inside drain. The water will flow along the string if it is touching the water source.

did you replace the seats and springs also??

No when I took the knobs off, that was the only part to remove. Not familiar with seats or springs.

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.

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?

danny hit it right on seats and springs lift out replace your good to go ...ben

I'll give it shot tomorrow. Thank you both for all of your help.
