I've installed a new bathroom faucet and everything is working fine except for the hot water connection. I am using ISP flexible tubes for both the hot & cold water connections. The cold water connection was a breeze. Unfortunately, the hot water leaks from the valve/ flex tube connection. I have tried three different flex tubes and I checked the threads on the water valve.

Thanks in advance.

Process of elimination suggests replacing the valve.I am guessing that the threads are just bad enough to either keep the supply tubes from fully seating or are worn just enough to allow water to pass through.Teflon tape may help you but I'd consider that a temporary fix.

The only other option I can think of is try a different brand of supply line and see if it works.

New valve it is! The valve is about 25 years old and has passed it's prime. Many thanks for the assistance.

Suggest you replace both while you are at it especially if they are both of that age.
