I replaced the bathtub faucets (they have never been replaced). Install the same measurements of Stem and seat. I have a continuous leak (dripping). Oh by the way the deviator does not have a seat, however there is a seat installed in pipe. Can you help?

You better repost your complaint with some details. What brand of valve? One handle or two or three knobs?

by the way the deviator does not have a seat, You're REALLY have to explain this one.
Wher's your diverter located? Spout of valve? And how do you know it doesn't have a seat?

however there is a seat installed in pipe What pipe are you referring to?
I need more facts and details. Regards, Tom
