How to fix a leak between water supply line and toilet tank?
Water supply to toilet tank – There’s a white, plastic, threaded fitting that has a flange on the bottom side of the toilet tank. The water supply line is attached to it. There is a leak between the flange and the tank. Please tell me how to fix this. I’ve never done any type of plumbing repairs before, and am not familiar with the terms, so I would appreciate everything in very simple terms. Thank you so much.
