    Default New faucets

    I'm installing new bathroom faucets. I have 3/8" copper pipe coming out of the wall. I purchased the 3/8" compression valves but I can't get them to fit. Can someone explain how this is done?

    Could you specify exactly where you're having the problem.

    The chrome shutoff valve would be a right angle fitting; the end going to the 3/8" chrome tube to the sink is connected with a coupling nut and compression ring to the metal threads on the body of the shutoff valve.

    The connector to the 3/8" copper tube coming out of the wall (stub-outs) should in your case be the same; when the little nut along with the little compression ring is attached to the threaded shutoff valve, the nut compresses the copper/ring to make a watertight seal.

    But these valves come in a wide variety of fittings to connect to various size water supply pipes; the one you bought at the store should have come with a little compression ring and nut that is fitted over the 3/8" copper tube & then attached by the nut to the shut-off valve.

    But there's a lot of different versions of the shutoff valve because the stubs can be 1/2" copper tubing, or even 3/4" copper tubing or threaded nipples coming out of the wall, & you may have picked up the wrong valve.

    Notice photos 6 & 7 on the TOH site, they show a straight shutoff instead of an angled shutoff, but the idea is the same, except they use a 1/2" threaded pipe coming thru the floor.

    You may have to take the valve back for one that will hook up to the 3/8" copper, or else buy an adapter fitting that goes from the 3/8" "stub-out" to the shutoff valve.

    Review the photos on the sites below, then post back.

    If you have any photos of your shutoff valve fitting, please post.
