Looks like a great start on the problem. I read your earlier post as I started looking at the 21RBS, but it wasn't as simple as yours. It's hard to tell from the LL pictures where your fresh water filler is, but if it's on the right near the galley you're home free. Just add a valve to take pressurized hot water under the sink and dump it into the unpressurized FW filler hose. A small 12V valve and cheap 12V timer could automate the process. From your diagram it would exercise the entire water system and be a lot easier on the battery than a 12V tank heater if you're off grid. It may also solve your bath/bed problem, but if not, adding some passive vents may be sufficient. If not the addition of one or two 12V computer fans should do it.

Keep us informed.

So there already is hot water a foot away from the fresh water fill.

The only reservation I have is whether the large plastic fill hose can withstand the 140F hot water. Can't find any info on the material. Any clue?

Perhaps this?

I'd need to find some kind of tee fitting to get from 1/2" to 1-1/4"

[font size="3"]I'll look when I get home. I didn't see any marking but it's tight where mine is. If you're right and it is PVC then no problem. Thanks
