I have a leak coming out of the spout of my Delta bathtub faucet. How do you replace the gaskets?

Single/two/three handle.. About how old is faucet?

Single, about five years old

OK... check out these pics.

One of them should be your valve or similar (if not, let me know).

Just need to shut water off and get to the seats and springs (#2 in left pic. #4 in right pic.) and replace them.

If this helped, please RATE THIS ANSWER. Thank you... Mark
