yes pex works great...3 of my 5 runs are pex tubing ( plumber friend had lots of leftovers when i started out ) works great. you can buy plastic fitting that work with it at home depot ( same manufacturer that the maple dealers sell just different sizing ) . to get a prefect fit i would warm with a pipe torch,slide clamps on, then fitting, tighten before it cools. still do the same process when repairing them but i made mainline fitting tool out of a old car bumper tripod screw jack, 2- medium visegrips, some scrap steel and 30 mins with bandsaw and little mig welder. works great also made a saddle drilling tool from a old saddle drilling bit someone gave me, saddles work great on pex too.
