First of all, this is a great site. I will be telling my friends about it. My commode just started leaking where the water line goes into the tank. There's a plastic nut and then there's a flat washer that resides against the tank itself. I have tried tightening the plastic nut - turning it clockwise - but it did not help any. I then turned it counter-clockwise with not better results. I will be replacing the commode in a month or two but hope I can get some suggestions on what I need to do next for now.
