        I recently purchased a house with an 80 gallon solar water heater that is 15 years old. My problem is that rust colored water flows for the first 30 seconds whenever I run the hot water. I have gotten mixed advise from the plumbers I have talked to. Some say that all the unit needs is to be drained well. Another says that I need a new unit.

        I have tried draining the unit twice but after a day, the rust water reappears. Is there a good way to drain/clean a water heater? Or am I stuck purchasing a new one.

          If the rusty water were in the water heater, it would not go away until you had used all the hot water in the tank. If it is just a small amount of rust, then it is due to steel pipe or fittings in the piping between the water heater and the faucet.
