    "Hi, it seems that the system you have in place is probably feed from a tank. Usually on older systems these were galvanised steel with a cathodic anode inside to stop the water rusting the tank this could be the issue or it could be water is stood to long heating and cooling creating chemicals.

    Does the water smell like sulphur (rotten egg )? If so it’s more then likely could be the issue.

    "Quite possible you have a split in heating coil in cylinder causing heating water to get into hot supplies, or you have a dead leg in hot water pipe somewhere with stagnant water"

    "Looking at the responses so far you have clearly described you have a megaflo system which is an unvented pressurized unit and would not include any older components such as a header tank. The question i would ask is this, was the megaflow cylinder put in after an older system removed? If so its likely the pipe work had not been fully flushed out, resulting in lining of residue from the old system. If the system is completely brand new, this is likely to be an issue with the temperature in the cylinder not being set at the right temperature causing lines that are not normally used commonly to cause bacteria growth in the lining of the copper or plastic pipe work. Our advice would to fully flush the system with a biocide chemical which would need to be completed by a professional, this then would require a litmus test to check PH scale of the water passing through the cylinder. Bacteria will not attach to the inside of a megaflo cylinder, but will through the copper network if not flushed correctly at time of install, plus the temperature settings."

    "Bacterial growth in either the cold water storage tank or the cylinder. Stored hot water needs to be kept at a temperature above Sixty degrees."
