Question

Answer 1

Find out WHY and WHERE it's leaking. Could be as simple as the compression fitting needs tightening. Could be a solder joint that's sprung a leak, which require a plumber to repair.

Answer 2

Fixing Leak Under Kitchen Sink

Answer 3

There can be several answers depending on what is wrong. If it is leaking at a fitting, you can try tightening the fitting or if possible cut off a small portion of the tubing and install a new Ferrell over the compression fitting and tighten.

If the tubing is leaking, then you can buy a new flexible line and install that, just be sure to measure the length before you head out to the store.

If it is a petcock leaking, you may be able to tighten the packing around the stem.

We would have to know where it was leaking, and what part is leaking to give you a good answer.

If you do have to cut the copper tubing, go to the home store and buy an mini-tubing cutter. They aren't that much.

Answer 4

If you have trouble finding where the leak is coming from; remove all containers from under the sink. Lay out a news paper and place containers on it. Check the next day for leaking bottles. Or wrap toilet paper around fittings and faucets and check the next day. It will be wet at point of leak. Or, it could possibly be where the chrome faucet mounts to the porcelain or stainless sink. If you flush the faucet with water to remove chemical cleaners you could be getting water under the flange. You need to either loosen up the mounting nuts from below and put plumbers putty around the faucet and refasten. Or just clean the area around the faucet flange and apply a light bead of clear silicon seal.

Answer 5

You are probably are going to have to replace the leaking section from one fitting to another. Not much you can do with patching up copper that will last although repair clamps available at any hardware might be the cheaper solution. Also if you decide to replace, you can use compression fittings to make the connections and avoid using a torch to do the job which is better left to a plumber. Good luck!

Answer 6

go to lowes or homedepot and get the new pipe fittings that you just push on your pipe. no glue or heat required. they are clalled "sea land" or "sea breeze" or something starting with sea. ask them at the store about them and how they work. I've been using them at work for a year and have only found one bad elbow. out of about a hundred fittings. all you will need is one fitting called a "union connector". cut your copper above and below the leak (get real close) and then install your fitting. if the copper is distorted it may not fit and you will have install a piece of hot water line from the closest good piece of copper you can find. talk to them at the store about that. they will help you.

Answer 7

Just need to replace the supply line from the hot faucet connection to the shut off. If the leak is just under the sink, it should be a fairly simple fix.

Answer 8

Did you turn it off under the sink? If so you will have to repair the water line between the tap and the sink faucet. It is best to get a flex line from a hardware store and install it between the under sink tap and the sink faucet. They come in a variety of lengths. and will bend and loop easily.

Answer 9

Plumbers tape works well
