i purchased a fixer upper, im finishing a half built garage , noticed 3 5/8 pex stubs on either side of the garage, and 2 sets in the back of the garage.
researched and found 5/8 is not common, fittings are hard to find and primarilly used for heat.
i filled each run and shop vac the water out. calculated each pex run to be about 100 to 180 feet.
the third run doesnt hold water or pressure.
it holds about 3/4 gallon so probably around 100 feet.
would it be practical or effective or even possible to snake 3/8 pex through as a sleeve instead of abandoning this loop?
