We just purchased a home with two 60 gal water tanks with the input cold water and output hot water hooked up in parallel (to the tanks, lines not crossed). That is no big deal but what is strange is what they have done with the tank drains. The drains on the tanks are connected in parallel, coming off with a T. This now single drain line goes through some type of regulator or one way valve. The line then goes through a box shaped pipe arrangement with three valves from that point the line goes to a pipe in the dry wall. I have not checked to check for sure if the drain line eventually ends up being dumped or is sent to a basement bathroom. Because I have all the valves open and I don't hear water running it looks like the drains are run to one of the bathrooms. I attached a diagram of the the plumbing arrangement and a picture.
It is the strange arrangement of the valves in the pipe box arrangement I can figure out. Any ideas of why they did what they did? What are the problems in using the water from the drain for heating?
