I want to add a hot water recirc line to my trailer

My issue is wasting good water while waiting for the hot water to flow.

Take that good water and use it to flush the toilet, or put it in said pitcher and chuck the water out the door.

Or use a 2 liter soda bottle to put that "extra" water in, then pour it back in the tank. Actually, make the wife do it since she's the one wasting the water.
