pinhole leak in galvi pipe

1424 Views 13 Replies 12 Participants Last post by  gregzoll
I was in the crawlspace under my house today stringing some phone wire and I noticed that the steel pipe that supplies water to my laundry room has a pinhole leak and is emitting a fine spray onto the subfloor. The crawlspace is VERY tight here - so tight I can't roll over. What is the best way to repair this leak?

A temporary repair that usually works is a piece of split hose ( radiator hose works well ) with a slightly smaller ID than the pipe OD and secured with a worm screw hose clamp. That section is thin and fragile so just tighten enough to stop the leak and plan on a permanent solution very soon.
Replace the pipe. Your steel pipe is failing- more leaks will come.
For the interim, you can buy a pipe repair/patch

A piece of rubber from an old inner tube or old hose and a hose clamp will fix the current leak. However I would expect more leak to turn up and you should plan on replacing all the galvi pipe soon.

Yes....that pinhole is just the first sympton of a pipe that is ready to fail.:yes:
some reason a picture of a pencil pops into my mind
would not be the first crawl space that had to have trenches dug to gain working room
Question for the plumbers..
When my gas line failed the gas company inserted plastic tubing so they didn't have to dig so much. Can this be done for water lines too ?
Thanks to you all. As I begin to think about replacing the galvi, what should I consider? If I replace with pvc I can do much of the work myself.
Look at PEX piping--If it meets code in your area it will be much simpler---no couplings ---no glue--very freeze/thaw tolerant---

Comes in a big roll,like a garden hose---

Use Pex for ease of install but be sure to use correct connections where needed. PVC water pipe is not allowed within th "house footprint"

Rubber Intertube and some hose clamps for a temp fix. Start pricing plumbers willing to pull Pex to replace that Galvanized, or do it yourself. The good thing about plumbers doing it, they can get the larger spools, and can prob have the job done in maybe three days, as long as all fixtures are easily accessible (Kitchen Sink potable water, bath sink & tub).
