: The pipe nipple on our bathtub faucet keeps leaking. We've tried everything- tape, pipe dope, it just will not make a good seal. the guy at the plumbing desk at the hardware store suggested just packing the area around the pipe with silicone caulking. he said that is what a plumber would do- is this correct? We've tried everything we can think of- any suggestions?
Just inside the tube spout- we bought a new tub spout package, plus took out the pipe that comes off the main pipe in the wall (sorry- I do not know the proper plumbing terms for this- my husband just mentioned that he was replacing the pipe nipple) the new pipe he put in was about 2 inches long (est) and threaded at both ends. He screwed that back into the main pipe in the wall and then put the plastic piece back on top and the faucet over the top of the plastic. It doesn't leak unless you pull the diverter on the top of the faucet to activate the shower, then it leaks from the join at the pipe nipple. Did this clear it up or did I just confuse matters worse? my husband said it isn't the valve- it's the connection to the pipe nipple?
