replacing bathroom faucets but not the same size?

Question

I went through a lot of trouble changing the piping for the shower knobs in the bathroom . you know how you get the set of knobs, shower head, and faucet. the knobs fit perfectly... we didn't change the shower head since there was nothing wrong with it... but then when putting the faucet back on, it chipped and now has a sharp edge on it. when attempting to replace it with the new one, it doesn't fit. what can i do for it to fit? is there some kind of adaptor?

i don't know the sizes of the pipe connection or the piece to the faucet.

Answer 1

By faucet, I am assuming you mean the bathtub spout. Standard pipe size for bathtubs is 1/2" but sometimes 3/4" pipe may be used to provide greater water flow and is typically used for oversized tubs or spa-type tubs that require more water. It sounds like you have either 1/2" pipes and a 3/4" spout or vice versa. Or, another possibility is the type of spout you have. Spouts are either threaded and need to be screwed on or are a slip type that slides over the pipe nipple and then secured with a set screw underneath the spout. If your pipe nipple is set up for slip on and your spout is for threaded fit (or again vice versa), the two won't go together. The easiest thing to do would be to measure the diameter of the nipple, take a photo of the nipple piece, (or take the two spouts) and go to your local hardware or plumbing supply store and have them help you. You may need to get a new spout or replace the pipe nipple. If the pipe nipple goes through a finished wall and you do not have access to the backside of the wall, it will be cheaper to just get a new spout of the correct size and type.

Answer 2

Take the old and new to the hardware store, they can give you a faucet that fits or an adapter to make the one you have work.
