Poly B okay to work?
Hi all
Question for you. I was going to install a fridge water line for a family member this weekend and had him send me some pics from under his sink where I'd tee off from. I'm about 99% sure its poly B pipe and its gonna be 15+ years old.It has copper fitting and copper rings. I'm a little worried if I have to shut the house water off the surge when it comes back on could burst a pipe. Is this something I should just not work on and advise him to replace it all?
Thanks!

The left valve looks to be hot water and dishwasher.
The right line already has a tee in its line. Is that tee for the ice maker ?

The right tee is for an old water filter appliance I'm going to remove. The actual install is not an issue for me. Mostly I'm trying to figure out if it is poly b piping.
The house was built in 1993.

Yes, it certainly looks like PB pipe.
I don't know that I'd specifically worry about working with it, but it is probably worthwhile sharing with your friend the risks with that type of pipe.

Yes, that looks like Quest/Poly B tubing, fittings and crimp rings. If installing a T make sure you buy one for poly B tubing and get the bare copper rings. Modern PEX fittings may look similar and fit but they don't work well on poly B.
If you are worried about a pressure shock when you turn the water back on you can do several things to help minimize it. Turn the water back on slowly. You can also open several fixtures around the house, turn the water on slowly and then go close the fixtures.

If you think there is a possibility of a system rupture..... try for it. This will point out any weak spots. You're better off having the system open when turning on instead of when you aren't there.

All good info thanks all.
I found the tee linked below 3/8 3/8 1/4 comp I'm going to install just after the shutoff so I don't have to do Poly B anything which will make my life easier. I think technically the fridge should get its own shutoff but whatever....
