When you have a beveled metal washer integrated into a faucet supply hose.....is that considered a one time tighten.
Hooking up a Grohe faucet and noticed the metal bevel washer on the supply hose built into it.

Let's pretend a angle stop goes bad and you replace that.
When you remove/reinstall the exisiting faucet supply hose, 9 times out of 10, will it still seat and Seal or will it leak ?
Just wondering....
