67, I am planning to vent the water tank. I know I need to do that. And I'll use plastic pipe, either PEX or the flexible vinyl tubing and fittings that are used in the pressure water systems in sailboats. My question is more about venting the drain side of the system. I'm only having a gray water tank and I'll drain that out into a bucket to dump in the woods most of the time. Plus I'm using those inline drain valves in lieu of P traps, to save space and add efficiency. If I can avoid the typical vent pipe thru the roof, I'd like to. And get the 4" of space inside in the bargain.

Are you using 6 volt batteries? They seem like a good solution. It appears the total usage for LEDs in my proposed system is just over 1 amp per day! Astonishing! It's the fridge that gets you. I just bought a Norcold that's 3 amps per hour, which is quite low on the scale of such things.

Such an interesting process!

D1, I would recommend a 1-1/2" ABS vent off of your plumbing system to allow the system to drain properly, including the draining of your gray water tank.

69, thanks for your reply. It just seems reasonable to suppose that with a sink and a shower drain, I could address the pressure issue when draining the gray water tank without adding a vent pipe. I don't have the answer but will do some homework and report back here.

Without the vent your sink will have a hard time draining. In fact, without a decent vent, your tank will have a hard time draining.

By the way, 69, what sort of a battery set-up are you using? I know you've thought your entire system out with great care...

Tiki2, I'm going to use the HepVo waterless trap for it's compact efficiency. It seem to me that it will act as a vent when water flows down a drain or out a gray water tank...?

Interesting product , it seems from their literature no additional vent would be required . Hope you will follow up with a report after putting it into service . Could be useful in an RV where they can sit for months at a time .

D1, we have a set of three 12V AGM batteries. I think I mentioned before that there was no grand theory involved. If anything it was the concept of brute strength in terms of electrical storage. Unfortunately, I didn't really calculate the amount of solar power needed for the batteries and whether I have the real estate to place them. It looks like I can do it, but just barely. So, if my camping style were to shift to long periods of dry camping I might have some problems. But, I would probably have some problems with water and waste storage as well.

I'm impressed by the HepVo as well. Let us all know how it works.

I used a cheap drill from harbor freight as the insulation dust is rough on the drill. I also purchased plastic abrasive brushes from harbor freight to remove some insulation. Mostly I scraped with plastic putty knives. Wore out four of the knives. Used the brush and drill in hard to get places.
