Reply to comment by HootblackDesiato in How do I change my shut off valve under my sink? by Parley_Pratts_Kin

Thanks. This will be my second option if I can’t just swap out movable parts in the valve. I believe it is a Pex line but is there anyway to know for sure? I’d just have to go buy a few tools if so since I don’t have any for working with Pex. Still cheaper than a plumber though.

Yeah, I don’t know how you’d know definitively if it’s PEX. The stuff I buy locally ((Home Depot, Texas) is not translucent like what you’re showing but a quick Google search shows that it comes that way. I don’t know of any other kind of plastic used for supply lines (but I’m not a plumber).

Also I saw a reference to PEX-A and PEX-B….. life is never simple!

Definitely better to replace that valve with a ball valve, along with the other one.

As others have mentioned that is pex, and is very easy to work with.you could install a sharkbite shutoff as long as the flexhose to the faucet will reach the new, slightly lower threads
