I put in the hot water bypass hose. put 3 gallons of pink antifreeze and ran all faucets until pink comes out but when i turn on the hot water,nothing happens. The pump turns on but nothing comes out and not even air. Why?????
What is this "bypass" hose you mention.?
most water heaters have only a cold-in. hot-out. most cases you just drain the hot water tank.
If you mean the 2 larger hoses that go to the engine, these only supply hot water from the engine to heat the fresh water in the hot water heater tank.

Do you have the valves turned to the proper position?
