Re: Water Tank Plumbing
You need to trace the lines to see for sure. I did that on my Boat so I could pump the ice box out through the water faucet. Two inlets, water Tank and Ice box, one discharge though the Boat. Someone might be doing something different here but I put a strainer on the ice box side so any floatsam would not foul the pump. I will flush some fresh behind the discharge water to prevent odors and I never move the discharge water through the water heater. Look carefully and you will see an arrow on the handle indicating flow.
Rereading your OP you could empty one Tank and switch rather than using both at the same time and running out of water.
