Has anyone had experience with a tank, say 55gal placed (using RTSII as example) up in the back where the Air con condensor and fans once were?
Supply would be from land source and an alternate aux water tank on board.
this would put the tank (and the volume behind it) about 5 foot in height, gives water a gravity feed from 2 to 3 foot to sink faucets.
I think the water pump gives us about 20lb psi, would the gravity system be comparable or still need pump assistance?
I have read where a tank has been installed up there but don't recall if gravity feed had ever been considered.
Any ideas? -cd |

every foot of elevation above the point of delivery gives a static pressure of approx 0.5 psi. With standard plumbing fixtures and pipe you would get a trickle. |

youd also make the bus very top heavy. The only time I do that is when I out somewhere that I can use the tank as a solar shower and use it static fed. But that is stationary.

I think better to keep that kind of weight as low as possible. 55 Gallons is somewhere around 450 pounds, I believe. I forget the calcs. But add a slosh factor in there and you have a lot of weight up high being thrown from side to side. One thing I thought about doing once, but have not tested, is to use some black PVC about 4 inch diam. and run it around the perimeter of the roof. Might serve as a solar outdoor shower and reserve water. The pipe would limit the sloshing and it wouldn't have to go all the way around if you only wanted a small capacity.

IF your water pump is giving low pressure , there can only be a few reasons,
1 located where it sucks , rather than pushes ,
2 A tooo small feed pipe in or out
3 Too small wires to the pump
4 a lousey pump.
For "live aboard" the Sureflow Blaster , usually used in yacht washdown systems or in bait well use, has a motor 3X the size of the RV pressure pumps , costs about $135.00 .
This is NO extravagance as the water pump is key to your enjoying the RV in use.

Just a fast thought, if top weight is a concern, and I can understand why it would be, why do some busnutz install their heavy gen/sets up there? Some of these units will easily outweigh a full water tank in weight. Is the slosh factor that criticle? cd |

A pressure of 5 PSI is created by mounting a water tank 11ft high.
Unless you have an air pump to pressureize the tank , or a fresh water pump , it sure will be slow coming out thye faucets.
BUT if you hook everything up with 1in or 1 1/2 pipe for feed you might get some volume.
