Pumping shower gray water above drain?

[warewolff]

Anyone try this? I think I'd like to keep both my fresh and gray water 100 gallon tanks right under my bed in the back. Getting the fresh water to the faucet with a pump should be no issue, but if my shower drain is below the top of my gray water tank I feel that this could be a big issue. Short of strapping my tanks underneath, is there any other option you guys have tried?

There are shower sump pumps for what you propose. If you have room underneath it's cheaper (no battery power required) to let gravity take care of the drains.

Just put the shower above the bed.

Wouldn't that make a possible rate of 1600 lbs on one side and to the rear? You will have to be a very very short person to use a shower on top of a 100 gal. tank. What dimensions?

No idea yet. I'm fairly competent but never delved into any welding and building a rack to hold ~800 gallon tank underneath the bus is a little intimidating. 1600lbs in the rear shouldn't be too much of an issue ... my bus is rated for 27,000lbs and the rear axle alone is close to 17,000lbs, although I'd have to check for an exact figure. I also like the idea of having the tanks nice and warm inside the bus in the event that we are traveling in sub zero temps.

You're only going to have about 800 lbs. Fresh and gray tanks won't be full at the same time. Fresh transfers to gray.

I think Jack (ok trunt) has a shower drain pump, check Honeysuckle Rose build.

Wow! Why didn't I think of that? Thanks for the tip, I'll check that out later.

What I did with my class C was just carry enough fresh water while traveling to just get by, ( to do dishes, maybe a shower every other day)you should try to avoid carrying all that weight all the time, then before heading in to Boondock top off water & fuel.

These mounts are no more difficult than a trailer hitch mount. You don't have to be a engineer just look at trailer hitch on a full size truck and what thickness material there using and copy it in a box that fits your tanks. If you cant weld cut it all out and take it to a local muffler shop and have them weld it up for you. They may even install it for you for a few bucks.

The toilets that pump the solids after they are ground up work pretty well there ion most homes with basement bathrooms.

Either way will work but stay away from sub zero temps. God put wheels on buses to go south in the winter.

We read your question and had pretty much the exact same idea. We have a 29 foot bus with the plan laid out with the tanks under the bed inside the nice warm insulation. We are stuck at not wanting to raise the floor for the drain and we don't know how to pump the water back to the grey. Just curious if you ended up figuring out your plan andv what ya did.

Thanks!!

My shower drain is 7" below the floor and the grey water tank is above the floor. I used a small 7 gal water carboy with a 12v submersible pump to lift the shower water into the grey tank.

The use of a shower sump pump like what is used on boats would be the answer.
