I have a Delta Model #35925 two handle widespread lavatory faucet and the hot water faucet is dripping out of the spout not from the handle. I have put 4 new cardridges in and it still leaks. HELP

Your #RP47422 Srem Unit icartridge sn't seating. Shut the water off and remove the cartridge. Check the inlet ports and place a pan over the open valve body. Now turn on the hot water on for a minute to flush out the supply and valve body. Now button it back up and check. Let me know, Tom

I tried that but it didn't work either...

Check the number of the replacement cartridge against number in my post. Tom

The number is the same as the one you gave me. I had Delta send these to me...

Well, something isn't allowing the cartridge to seat closed. If a replacement cartridge didn't work then the problem's in the valve body itself.
