Water Tank Level Sensor is Leaking

As you can see in the photo (which is side ways unfortunately) in the link in the first post, it looks like it is leaking from the center not from the spin welded flange. Here is a link to a picture of the spin weld sensor that is used:

It doesn't need a grommet because the screw doesn't protrude into the tank. In other words, even with the screw removed it should not leak. Am I right?

I think the spin weld sensor is leaking between the metal probe sensor and the plastic weld flange? I think when I try to tighten or loosen the the screw the metal probe sensor is twisting as well?

Do you think LeakSeal flexible rubber coating would stop the leak if I sprayed it on the screw and probe in the middle of the spin weld sensor? , has anybody ever used it?

Thanks

You are looking for a simple fix. There is none. Yes, I guess it is possible that the metal threads for the screw are leaking, but we get back to the original debate. The metal nutsert maybe got hot enough during the spin weld process to develop minor cracks and is leaking. Regardless, I don't understand your issue. You state it is under warranty. GET IT FIXED UNDER WARRANTY. Don't try to do a half ss repair. I replace tanks 2 or 3 times a year under warranty for this same problem. There is NO rubber on the inside/backside of that spin on probe. If you remove the wire mount screw, this type fitting will not have water shoot out the hole. It has a rounded solid rivet type backside that senses the water. Doug
