We have a newer house (2014) with Pex plumbing. I am do some renovating to the builder basic powder room and notice that all the shut off valves have the supply line permanently attached. The supply line is white plastic with a small amount of silver braiding reinforcement and is permanently crimped in place.
I always thought the supply lines were a maintenance item that should be replaced on occasion. So I'm wondering if I should replace the shutoff valves while I have everything taken apart or if these non-replaceable supply lines are meant to last the life of the house.
It would definitely be easier to swap them out now because they aren't buried in a vanity or under a toilet since the room has been cleared out and because part of the decor we are doing is a a half inch think layer of weather barnwood on the wall with all the valves. which will give me very little to no slack to replace the valves later.
Any advice would be greatly appreciated. Thanks in advance!
