I'm getting ready to de-winterize our TT. There are these 3 valves all close to each other. I'm assuming one is the shut off for hot, one shut off for cold and the valve on the vertical lines is the by-pass. Am I correct? What would the shut offs for hot and cold be used for? This is our first TT so this is all new to us.
The ones going into the tank are to keep antifreeze from going into the tank. When they are closed, the vertical one needs to be open. After you flush the antifreeze out, open the ones going into the tank and close the vertical one.
