I am the new owner of a 31' sunsetter w/ a 4 gal HW tank. I had no problem getting the antifreeze out of the lines. But, when I put water from the main tank into the HW tank the the HW lines come out pink. I have run a whole tank of clean cold water through the HW lines via the HW tank. But, it STILL has some pink. I tried draining the main lines underneath with and w/o the faucet open and still dont get all the punk stuff out. I even let the ump run w/ the caps off the main drains and just ran water through it that way and still have water mcoming out pink!
Should I open all hw lines at once and let another whole tank run through it? I don't want to burn out the pump or something.
PLEASE HELP
