Hot water and boondocking

[Gardner Yeaw]

We took a 4 day trip and had only power available. I left with a
full water tank and mostly empty grey and black tanks. By the last
day I had about 1/4 tank of water left. I began to think about ways
to conserve water to streach the time we could stay. One thought was
the waste of water waiting for the sink or shower hot water to come
up to temperature. It was cold outside so it took a while, wasted
water and holding tank capacity.

In hotels/motels/large buildings they use a circulating system
that keeps the hot water supply hot so you don't wait for hot water
at the tub or tap. It would seem that this could be done in an RV by
adding a return line from the far end of the hot water system, a one-
way valve and a pump. Then all you would need to do is activate the
pump for a minute or so to charge the system, and then start the
shower. It would conserve the water supply as well as the grey tank
space.

Has anyone seen this kind of system in use?
