I found that a wood screw got put in a panel next to the water tank. That screw was too long. And the very tip of that screw made a tiny hole in the side of the tank. It never leaked around the screw. I think you can use a soldering copper, or gun to melt that plastic back together to fill the hole. RIGHT?Bob Dunahugh78 Royale.

Right. Use low heat, probably a 20-30watt iron. The edge of the welded area tends to thin too much. I'd try to find a piece of excess to use as a filler.

Or you could plug it with a stainless sheet metal screw.

Bob,
The problem is that, PE (polyethylene) when heated in air becomes "No Longer PE". That is why Dale Ropp "flame treated" the black tank that he patched at Chippewa Falls. I have seen open welding of PE be successful, but more often than that, I have seen failures.
Just run a Stainless Steel screw in. It didn't leak last time with just a screw in it. The smallest you can find. Do not use any sealer as it will not bond to the PE and if it is not certified for drinking water, it may contain nasty stuff to keep it from growing mold.

Or even put a rubber washer under the screw head but probably won't be
necessary.
