Hey everyone. I am adding a bathroom basement and will need to reloctate some of my baseboard water pipes that will be conflicting with the new layout. I was looking into switching out most of the copper for oxygen free pex. What fittings are best to use with PEX? Shark bite, compression, expansion, ect? I was planning on locating the new lines within metal stuff furring wall. Am I better off using copper and doing pro press? Thanks for the help!

I like brass inserts with brass crimp rings. Just my preference. Dont care for plastic inserts. Or the pex a expansion rings are good too, which can only be used on pex a pipe. Those are my preferences. More on the expensive side unless you can rent the tools from somewhere. Fittings are kind of pricey as well. Especially for a larger job.
i agree with Justin i had a pipe burst a couple of years ago...and i repiped all the domestic water...and ran oxygen free pex for another zone of heat...i bought my pex tool from mil3 they have been around for 30 years warranty and repair their tools very easy to do ......everyone has their opinion...this is just mine...
Thanks for the replies everyone. Any issues with the crimp fittings holding up over time? For supports every 8 feet? Also do you guys have a recommendation for a hand tool for crimping the fittings? Hoping for something on the cheaper end. Thanks.

The hand crimpers run between 60-100 for one. Also, I prefer to support mine every 3-4 feet. Just me. As for longevity, look up people that do instructional videos or have more information on them. Not really sure how long they last. Just know I haven't had to go back and change one, unless it was crimped bad.

But you can check out a plumbing supplier and see if they rent them and for how much.
when i ran my pex i supported it evey floor joist...not sure how far your running or if there are branches i have heard of people clipping a pvc sleeve up so you can just push the pex thru...my pex has been up for 3 years no issues
check out mil3 that's what i bought 85 bucks each 1/2 and 3/4 i did a lot of research before i bought them check out their web site
When using oxygen barrier pex, support it every joist span if you can especially if it's going to be exposed. Otherwise the first time you turn the heat on its going to all look like a sore dick no matter how neat you run it.
You can use the crimp fittings on heating without issue as long as water is pushed by a circulator, and not relying on a gravity system. I personally prefer the Upenor expansion system for am my installs, but to each their own.

We replaced the water line from the meter , in the alley , to the house , almost 2-1/2 years ago . We used PEX from Home Depot . With the brass fittings & copper crimp rings .
I used 1" PEX & had to buy the crimp tool ( 1/2" to 1" ) . About $ 125 , at the time . If I had used 3/4" , I could have rented one for about $ 10 a day .
