Thanks for the tips. Have the cutters and pex pipe. Need to buy the crimp and crimp tool. The piping there now is the clear braided white & redish. I assume I can replace that with regular blue pex (cold) red pex (hot). I was told in RV's Pex is an attractor for Rodents...
Cut the T off, cut off section pinholes, reattach. Probably do this one part see how it goes, not keen on replacing sections where no leaks (yet). I had TT for 12 years never had pinhole, pipe leak, many other things not those. This has me curious because told acidic water won't harm pex or braided pipe, only copper. Guess that not true. High water pressure and winterization failure can cause pinhole leaks.
