Blue water line leak; how to repair

Recommended Posts

i have discovered a small pin hole in the blue water line below the floor of the outside storage compartment. (See photo)
Please advise repair advice. Such as what is the pipe type and what product do I use to repair? I assume I need to cut out a pipe section and replace? If so what fittings should I use? Any repair advice would be greatly appreciated.

@Gliddenwoods I fixed the orientation of your pictures, and see below for a possible fix to your leak.


Pretty sure you have 1/2" pex B piping in your rig, that's what we have in our 2023 LEII. I doubt you have the proper tools to crimp a joint to fix that leak, so the easiest way probably is....
1) Shut off the water supply
2) Cut your pipe squarely and ensure both end are free of debris
3) Join the 2 end with a push to connect coupling like this

Along with the push to connect or shark bite fittings you will need a pex cutter as well. $8 at HF. You can also pushase 4’ lengths of 1/2” blue and red pex at HD or Lowes. I always carry a few spares of pex (link) for quick emergency repairs of our Ollie or to help someone else out.

I’ve never seen or heard of a pin hole developing in pex, so I Googled it. Found a huge range of causes, mostly speculation, to include over pressuring, chemical degradation (such as chlorination), animal gnawing, physical impact, freeze exposure, manufacture defects, and so on and so forth. I would advise replacing the entire section of pex rather than splicing with a coupler at the leak point.
