Dry Camping: Many Power Solutions. What about Waste/Water?

I also added a hot water circulation system. Mostly to keep the pipes from freezing when visiting the snow. And it does help minimize water use by having hot a lot closer to the faucet.

I used an El-Cid 12v pump and a Grundfos valve.

I just let the built-in pump do the work, but then it is just intermittent. The irrigation valve works well for cold water, but I don't know what would happen if it was constantly receiving hot. Beside, the inline valves are only $12 or so.
