This might be useful for winter camping. Hot water won't freeze up. Although shouldn't the recirculation return to the hot water tank, not the main tank? At least this is how I plumbed my house's recirc. heat.

The water needs to return to the low pressure side of the pump to cause a pressure drop so the pump will start. Returning to the water heater has no pressure drop because it's on the pressure side of the pump so the pump won't activate because no pressuredrophappens. You could return water to the cold Input of the water heater but to make it work, you would need a small pump and a check valve to prevent backflow. Another way to connect if you can make room is to put the return connection to the pipe between the tank and the pump. This way, there is a low pressure connection to the fresh tank and the water will recirulate directly into the intake side of the pump and get pumped right back out into the system, not into the tank

neet idea but I think if I were to implement this I would not return it to the tank but rather create a loop from the hot water heater and use a small circ pump. that way you could use it even if you had water hookups but now sewer.

True, it won't work when hooked up to citi water but then it's an endless supply of water so running the water to get hot doesn't matter since water is unlimited. When hooked up to city water, I run the water anyway to get the hose smell and taste from the hose out of the line. I have a blue hose that isn't supposed to smell but it does, just not as bad as the white hose.

I thought this was about not filling the waist take up as fast. I have camped in several places that have water and power but you dump on the way out if there is a dump. ya I have both a blue and white house in the 5th wheel, the only thing I noticed about the blue one is it costs more ;)
