You didn’t show getting those bolts off of the bottom of the faucet, they are usually stuck on and a pain in the ass to get off, you made it look easy breezy, good video non the less.
What if your supply line is stuck to the water valve? I cant even use the old crappy plastic lines with the new faucet, but I can't get the bottom of the old line disconnected
I done got a mess going on the valve broke off and oh well cut the water off reaplace it well I did but o got it too tight and it cracked so it leaks lol then now for some reason I fixed all that right and have no leaks but now I can’t get good water pressure at the faucet anymore. 🙄
It is that shut off valve under your sink - one for hot and one for the cold supply lines. When he is working on it he first turns them both to off position and then tries to turn on the faucet just to make sure no water is in system.
