I bought Flex Seal Tape (actually a Gorilla Tape knockoff) this morning and pealed the freshwater tank heating pad off. To my surprise, the heating pad was covering a second rigidity "hole" manufactured into the tank from bottom to top. Surprised to say the least. I doubt if the heating pad would do much good warming up a hole.
Anyway, I examined the tank surface where the pad had been attached and all around it. No cracks, no holes. This got me pretty flustered, because I started thinking the leak was coming from the area between the tank and one of the beams that support the tank -- an area totally inaccessible to seal-tape. If there was a leak between the tank and the beam, it might have flowed across the bottom surface of the tank to the heating pad and merely appeared to be coming from under the pad. If that was the case and the leak was on the bottom of the tank and inaccessible to patching, I'd probably have to abandon living in the RV.
I wasn't able to refill the freshwater tank with water (and attempt to identify the source of the leak) until this afternoon -- because the builder was borrowing my water hose.
Finally got access to the water hose and started filling the tank. We'd used some water since I last saw the leak, so it took several minutes of filling the tank back up before the leak started up again.
Believe it or not, the leak originated from the near the top of the rigidity-hole that was covered by the heating pad. Near the top of the hole! And that's good news (in a twisted sort of way) -- because it means I can fill the freshwater tank more than 3/4 full before leaking. I'll have to refill the tank more often to stay hydrated, but I'm not out of bullets. Oh, lucky me.
I haven't isolated the actual leaking-breach yet. It was getting dark and I didn't have a flashlight. Reaching into the hole, it feels like the top of the hole is covered with felt or tar-paper. It's loose, not sealed. Just guessing, but I'm think the hole is directly under the RV floor positioned between the island and the cook-top counter. In other words, completely inaccessible.
As for addressing the leak, the only thing I can think to do at this point is get a mirror-on-a-stick and try to examine the top of the hole from the bottom side in hopes of locating the breach. Doesn't sound very promising.
Suggestions? Cate&Rob ??
