    Can I repair a pinhole leak in toilet h20 feed pex with self fusing pipe repair tape
    I have a pinhole leak in the toilet water feed pex tubing. It's so small, I can flush the toilet 12 times and more without a drip, but after 7 years it dripped occasionally and stained the dry wall. Can I successfully repair this without removing and replacing all the Pex and use self fusing pipe repair tape? Thanks, Laurie

    Please restate your problem. What you are telling us is not logical. A water supply pipe with pin hole leak would leak all the time. The number of times the toilet is flushed would not have an effect.

    The only way flushing the toilet a number of times could create the appearance of a leak in a supply pipe would be if the humidity is quite high and the flow of water in the pipe is cooling the pipe and condensation is occurring.

    Tell what you see and if possible show a picture.

    What is PEX? Toilet riser pipes are not usually PEX.

    It isn't butylene is, the stuff that was outlawed? In use from 1978-95. I used it for everything in 1982 because it was cheap and easy to put fittings on. Mine was grey. More rubbery looking than PEX.

    PEX is easy to fix. Cut it where the pinhole is, and use SharkBite coupling to reconnect the two ends. Done in 2 minutes

    With a "leak" this small I'd consider that it could be condensation during warm weather. Did it ever drip of leak in the winter?
