What in tarnation is this water supply line and can it be replaces

[fknorco]

Alright so long story short

1. Buy a second bidet because husband became part of bidet fan club
2. Can't install it because the angle between the supply line, t-valve, and toilet seat is too awkward
3. Go to Walmart and like an idiot I am buy a water line REPLACEMENT instead of extender
4. Whatever, I am too darn lazy to drive and live in the middle of nowhere
5. Look up how to replace the stupid thing but of course! My shut off valve set up looks nothing like the videos
6. Tried to unscrew the top of the shut off valve but it doesn't move but it will rotate on the bottom.

So how do I replace this? If it's easier to get an extender I will I'm just not going into town for a couple of days but I would really like to get this fixed before then. Sorry for the crappy pictures I was trying to hold a flashlight and take a picture at the same time

You need a plumber.

Show us the connection to the toilet tank. This is my hookup. FLUSH THE TOILET TO DRAIN THE TANK.Turn your valve off and disconnect line from the tank , install the T and your bidet supply line. Hope this helps .

Turn your water off at the main valve to the whole home and drain the system down.

Cut your old water valve off to the toilet with plastic pipe cutters.

Install this valve after you’ve read the instructions completely and understand them. Follow the instructions.
