I have Pex tubing running through my whole house. In the master bath it froze last year and this year due to a deep freeze here in Texas. It does that in this area of the house only because it faces an outside wall. So far, I have no issues with the tubing busting or leaking.
I would not worry about the PEX tubing fails at say 0 F. The most likely failure points are any brass fittings and less so the plastic fittings. I had a quality (as not made in China) brass ball valve cracked way above 0 F that is an RV fresh water drain valve that was under next to no pressure. I would say that PEX plumbing still most resistant to freezing of all, despite the weak points are the fittings.
thank u so much .. i live on a hill in w’tn, flat land. can’t explain the wind kicking up here .makes the summer times so much better but the winters so much colder . it’s a sacrifice. as we speak my pex is frozen . put in a couple years back. it’s frozen i know 1 maybe 2x’s. we are very rural here and pex hasn’t been introduced that long . we shall see.
I’ve noticed in most of your videos you use 90° fittings on Uponor PEX A. do you have a reason for not using the sweep brackets, to avoid a fitting? In electric work less connections equals less opportunity for open circuits.
I'm wondering about this "pressure" test. The test sample is completely filled with water, no air pockets. Pressure is applied and then the valve is closed. Supposedly you cannot compress a liquid (at least at typical water pressures). So when the valve is closed, is there really any pressure in the test sample? Just wondering...
I'm curious if half inch text will freeze under ground at 2 ft without insulation? Temperatures around 15°. I do understand if they're not insulated coming out of the ground they will freeze. But I have also heard underground pipes will not freeze?
This is digging into what I'm looking for, I'm satisfied with the pex A pipe holdin up, I guess my question and you're showing part of it is how well do the fittings hold up, The elbow seems to be pex plastic, it seems like that being full of water would freeze and rupture, as well as the valve you have own there, most ballvalves or stems, brass or gav. would freeze and burst, These do not seem to be effected. Would you agree? I'm in the mountains of VA, it's not uncommon for us to have 2 weeks at a time with the temps 20 degree or less. The pex I'm sure would hold up, but elbows and valves, ?? still looking for answers.
Yes, the fittings are at bigger risk. This video is top to bottom A+. Conceptually and in practice, maybe the best RUclips ever...well done!
Keep up the great work! 1st yr Plumbing apprentice here and you helped me to have a better visual understanding of a rough in: vent,stack etc.

Your insulation sucks my man.. add some more

Great videos with quick answers. Keep em coming. Maybe a video of using coiled pipe versus straight sticks with joints. Great job!
Great tips from a phenomenal plumber! ☺️👍🏻
👍 love the plumbing tip at end

Great information
thank U so much 4 this test!! *a helpful test* !! I would like to see the R20 black pipe foam insulation tested!
Appreciate ya, solid videos.
Thanks
Good info. Can repeat the freeze-thaw test a dozen times to see what fails. I suspect the fittings let go or start to leak after a few cycles.
I’ve been catching some of the PEX A cracking. Not sure if it’s a bad batch from the factory.

Copper dog all day
And heat tape
Cycle it a few times, thaw freeze and repeat 10 X
