Any advise on pex....

I'm re-piping the house and running Uponor pex. I have the Milwaukee Expander. Wow, what a tool! I was able to 1" with the expander that I never could have done with the manual kit. Anyway, it is a manifold system. Longest run of hot water from my tankless will be 16' ;)



My question is, how are you terminating under the sinks, toilets for a secure mount? Any suggestion, much appreciated. I'm a copper guy by training and inclination, but water quality issues pointed to pex here.

    PEX outside the wall

    using the Uponor EP angle and straight stops is what we use most of the time.  They have excellent resistance to hard water and are very low cost.  You want to to exercise each valve 3-5 times before you apply pressure to the system -- prevents channeling in the lube on the ceramic disc, which has created slow drips in a few of them.  Assuming it's a stud wall, a Sioux Chief Strong Arm with PEX Bend Lock Block goes behind it.



    If you want a more traditional look, Sioux Chief has a range of F1960 copper stub outs that put the PEX joint back inside the wall and let you use standard copper compression valves.  Check out some of the Dahl F1960 options there.

    Stub ells

    Why not use the propex stub ells. You can secure them just like copper. They can be sweat right into shower valves. Super clean looking

    Lots of ways

    guide channel with the plate if you want not joints behind the wall, but I use the propex copper stub outs and the copper multi plate when ever I do it, shower valves are the tougher of the items to pex in, I normally hard pipe them for 12"s or so and then convert to the pex, fastening the hard pipe to my wood supports....



    I have gone through 11 of them milwaukee tools, now I buy the larger 18v ones and they seem to last, but for the most part I use the hand tool myself, my guys love the power tool and I love the time they save, but for me Im never in a hurry and could use the exercise...
