I've just bought a bidet and assumed that replacing the water supply line would be easy, this is turning out to be a bad assumption. After unscrewing both sides neither side seems to come out, I've tried pulling on both sides and the top will come down a bit but it feels like it's under heavy tension and as soon as I let go it's pulled back into position as if something is holding it in place. The bottom side doesn't move at all and it feels like pulling on it that I'm just going to rip the valve out of the wall.

Do I just need to pull harder or is it possible that the top is somehow connected to something inside the toilet? Certainly this isn't some valve/line/toilet package that isn't meant to be separated?

Yes pull harder. The plastic has some flex but because it is “straight” it is kind of spring loaded pushing it self back.

  • Okay thanks, and I assume this goes for both sides? How sturdy is the line coming out of the wall? It move around so much I feel like I'm just going to snap it

  • Once you have 1 side out the other will come out easily if the tubing is old it may crack but you will have to flex it a little to get it out of the fitting.

  • Support the valve with one hand and bend the plastic pipe down from the top as it more tapered.+1
