Fresh water tank leak

I had a broken fill fitting on my old water tank. It was cracking and had been repaired with plastic putty several times. None of the putties would stick to the plastic long term. As a last resort I wrapped Flex Seal tape all around it, and it stopped leaking. That was almost a year ago and it's still holding great.

Understood. They aren't typically glued on but they "spin welded". Regardless - the tank isn't pressurized and any "leak" should be able to be contained without extensive effort. Perhaps you used the wrong sized fitting or maybe an epoxy which isn't compatible with your tank? In my case I removed the old valve and replaced ... have you tried that? The leak I had sounds similar to yours ... constant use of the drain valve resulted in weakening and leak from the valve attachment.

Hi ksg5000,

The leak isn't the valve but rather the fitting the valve screws into, which appears to be glued into the tank.

FW tank isn't under pressure and in many cases the simple replacement of the valve works ... adding appropriate epoxy should have been INSURANCE and nothing should get beyond that. You might take a closer look double check where the leak is coming from. Just my 02. In my case I removed the tank - replaced the valve - filled the tank to insure it wasn't leaking - then replaced the tank.

Been to EBay, no luck, clean and dry, sigh.

Try E bay for a new tank.

As for your repair was it clean and dry when you tried?
