Warewolf, how did you end up connecting your system? I just ordered an L10 and am looking into options.

2 pumps the way to go?
one water tank?
did you use a purge tank or regulator tank - or are the pump(s) connected directly to the water tank?

thank you!

Just one pump. 1/2" PEX comes out of my water tank and into pump. Hot/cold T is upstream. My pressure is sufficient.

Long-distance plumbing

One pump is adequate. No need for more than 1. Just make sure you can get more than 1/2gpm when factoring in the pressure drop of the pipe size and length (and any other potential flow restrictions you build into the plumbing system)

I'm not a bus expert, but if you have plumbing questions, fire away!
I would love some help plumbing! I am having my first child on my bus in a month and trying to figure out the plumbing before then... trust me wasn't my first option but here we are! I was set on the Sureflo 4008 3gpm - I just got done installing a rain barrel that I will either fill or let be filled with potable water on the back of my 22ft Bluebird....

I foolishly thought that I could just pump water up to the kitchen 15 or so feet away and a couple of feet vertical from the barrel spout but then read the manual and it has to be 6ft or closer to the water source. I could just use the rain barrel as storage and fill 2.5 or 5 gal jugs when I need to but given my circumstance, I want to be able to pump water into the cabin when I need it, for now.

Electricity is also in the works, amperage and voltage are all covered so I just need to figure out a way to pump long distance - and eventually how I'll heat it when I need to. Without much experience I'm not able to put plans together very well- help!

I just downloaded the manual. What it says is the pump must be within 6 ft of the water source (tank). It makes no mention of how far it will pump (push) Your 22 foot bus would never have such a long water system to be a problem.

These pumps don't lift (suck) very well but, they push quite well. If you have a water outlet on the bottom of the tank and mount the pump as low as the outlet it will be more than enough. Even if you stick a hose in the top of a barrel and mount the pump on top of it, it would meet those specs.
