Greetining,
After some bathroom remodelling, I reinstalled a pedistal bathroom sink. I used copper tubing to connect the supply to the faucet. However the connections from the tube to the faucet keeps leeking. What am I doing wrong? Dan

Did you use cone washers and friction rings?

No, sure didn't.

Well, I'd say we found your problem.

What size copper tube are you using, 3/8?

That will be the most common size when you're hunting for parts.

Good luck.

Probably 3/8. Went to Ace hardware, but I think they gave me the wrong thing. The rubber washer is red and flat and when I tried to use it I could not get the thread started. It is not cone shape like your photo. Dan

Okay, but don't forget the friction rings -- The basin nut will shred the washer if you don't use 'em.

Do the friction rings go directly behind the rubber washer or behind the head of the tube?

The anti-friction ring will install at the base of the cone and on top of the nut.
I'm a old time plumber. In my day the pipe size was determined by what it will carry,(I.D.) Are we talking 3/8" ID or OD. They do make 1/4" chrome supply tubes with a built in nose cone for easy installation. Check it out. Good luck, Tom

It's the chrome supply tube with built in nose. So it does not look like I need the rubber cone. Still, it leaks. Any suggestions? Dan

Try coating the nose cone with pipe joint compound and cranking down on it. Good luck, Tom
