    My copper in slab just started leaking again so not going there. I want to use good pex in attic. I am on well. Hard water. I know thats what caused leaks. Also been there 33 yrs. I cant afford expansion tool for plastic fittings so Im gonna have to use the brass fittings i guess( feel like they gonna leak mayb 10 yrs). Which ones and which compression ring? Stainless or crimp ring..You're opinion on any and all of this would be appreciated.also thinking about a filter of some sort.

    hello i had i pie burst in my basement due to freezing weather and an amateur

    renovation I'm a copper guy pro press or soldering anyway i had to install over 300' i chose the copper crimp method crimp tool is made by Mil3 they have been around for 30 yrs warranty and repair/calibrate their tools i bought a 1/2
    inch and 3/4 inch for about 85 each very easy to work with everyone has their
    opinion but i liked this one there is another method called cinch method
    stainless steel clamps that cinch on the side don't forget if you do any
    heat work the pex must have an OXYGEN BARRIER or it will rot your boiler

    not shark bite fittings, this method has been around for 30 years check out Mil3

    As a professional I don’t trust many things other then copper soldering or expanding pex, crimping might be a good option for you, just be ready to fix some leaks afterwards.as for price those shark pipes you’re trying are very expensive and haven’t been tested trough time, if you’re gonna use them make sure you’re water pressure is low if not add a prv

    Also maybe some one else here can help here, but I believed that hard water is especially bad for pex , (if too much chlorine in water) the pipe willl fail over time.research it and if needed maybe add a softer/filter system

    Chlorine was known to attack polybutylene piping. As far as I know there is no such claims for pex

    For well water I would consider the plastic pex crimp on fittings.

    If cost is an issuse. goggle

    NIBCO 1/2" & 3/4" Block Combo PEX Crimp Tool

    Lot slower to use but almost fool proof. And just for one job. And gets in tight places.

    Long straight runs in an attic. Run thru some PVC pipe. Pvc pipe cheap enough. Possiable to limit where a leak will come thru from an attic. Protects since are some rare cases a squirrel in the attic will eat thru pex.

    Dont say if freezeing part of the country. But can even run pvc thru the ceiling above a water heater.
    Some heat will travel up into the PVC to add a little heat. I myself do it this way for all pex in an attic. So no freezing and not even any joints in the attic. But add extra work.

    Just some ideas i will add.

    Hmm.. Does iron sediment adversely affect PEX? I'm thinking of using PEX in some places as well, but I'm also on well water and there is a lot of iron in it.

    On well water seems to be best to go with the plastic fittings.

    I remember the one I did on a well about 10 years ago. Had problems with the brass fittings after only 4 years.

    Only job I had a problem with.
