What's the recommended spacing for securing pex to studs? Do you think it's OK to leave long stretches (8-10') just laying between floors?
Also from a previous professional plumber job I have these inserts that hold the pex where they go through the floor. I could not find them anywhere so I just drilled a hole slightly larger and might put some spray foam around them although they will probably still touch some wood. Is that OK?
Does PEX not need water hammer arrestors since it's plastic? I didn't see any on the previous pro job.
