I was recently at a rally and the neighbor coach mentioned a way to not have to dump the cold water into the gray tank while waiting for the hot water to make it to the rear sink faucet or shower. He told me that he had a switch mounted in the bathroom near the sink and turned it on prior to turning on the hot water faucet. After a very short period he would then turn on the hot water faucet and there was no more waiting for the hot water. I had a drawing that I made for my motorhome (Winnebago product) and I added the above mentioned system to show the additional pump and fittings to make the system work as was shown to me. I don't know if it applies to other RV's in general.
