Bob,

The Loctite glue I linked (https://www.loctiteproducts.com/products...81925.html) states it glues polyethylene.

I used it on my polyethylene fresh water tank to reglue the main drain fitting on that tank. Since it’s the drain and at the bottom of the tank, it’s under the most pressure. It was glued close to 10 years before I sold the coach. It hadn’t started leaking in that amount of time.
