How do you fix a pin hole leak in a copper pipe?

Question

My ceiling is coming down because of a pin hole leak in the plumbing system. Whats the best way to seal it?

Answer 1

Depending on what it is, you can either buy these bands made of rubber that have hose clamps and tighten this around the hole, stopping the leak, or you could also drain the water out of the line, cut that small piece out, and sweat a new coupling in to reconnect the part you just cut apart. If you don't know how to solder a fitting in, I'd go to the hardware store and ask about a repair coupling, I know they make them.

Answer 2

Any hardware store will sell an epoxy sealer that is specifically made for copper pipe leaks. They also carry a rubber sleeve that clamps onto the leak. (this method is much easier and more effective.)
However, neither is the ideal solution. The section of pipe that has the leak should be cut out and a new length of pipe can be soldered on using repair couplings. (After the water is turned off, and the pipe drained, of course)
The other thing to think about is how did the leak happen.
Often, older pipes that are in homes with 'hard' water can corrode
to the point of leaking. Wouldn't hurt to call a plumber.

Answer 3

Most likely you're talking about a leak in a supply line between the shutoff valve and a sink or other fixture. If so, people don't repair these, they replace them. These are usually chromed and a little bigger than a pencil compared to a supply pipe before the shut off which will be as big as your finger. You can probably replace this yourself. If this is what's leaking, it will cost $3 to replace and any friend can help you with a couple of wrenches. These come in plastic also now and some are real flexible. I had a misty leak and traced the cause to storing bowl cleaner with the cap off, under the sink and the acidic fumes from the cleaner corroded the pipe. It was ready to leak in a lot of places.

Answer 6

Copper pipe at times has to be spot welded (soldered if you like) using brass or a few other metals. Make sure you clean the damaged area well before welding or soldering, so as to make a good finish that wont leak again. Be very careful however if this has to be done on pipes carrying gas or any other explosive products. Thanks, Larry

Answer 7

Cut the pipe on either end of the pin hole and attach a new piece of pipe. You can use two fittings on each end with plumbers tape or you can solder on the new piece. Be sure to flush the pipe clean if it's the pipe that has the drinking water run through it.

Answer 8

Step 1,cut off water to entire house. step 2, figure out what size pipe is leaking ( 1/2 or 3/4 inch normally ) go to hardware or big box store. buy compression coupling and thumb cutters for copper pipe. make sure water is off by opening highest faucet and rear outside faucet. using thumb cutters, cut pipe at pinhole,place compression coupling in cut and tighten. note: a compression coupling has 2 nuts,1 on each side, 2 ferrells, 1 on each side,and coupling body, tightenng the nuts willseal pipe
