Can anyone advise me on a problem with a Delta boiler.The hot water in the house has been slightly discoloured for a few months now(light black colour).The boiler is only 6 years old.My plumber has told me that there is a crack internally and that the hot water is mixing with the heating water - therefore the boiler is crocked and needs to be replaced.Is this true or could there be another less expensive problem ?
