Water treatments would go a long way, but changing out the anodes would make
a difference, too. But that depends on whether you have electric or gas.
Gas has black pipe running (a electric path to copper waterpipe), but today
it doesn't have to be. Technically you could change out the gas piping for
a flexible plastic and end the problem once and for all (like using optical
to end ground hums). Personally, I just have my gas water heater hooked up
to the water pipe and change the anode connection every couple of years.
The last water heater lasted 18 years. This one's into it's sixth year and
clean as a whistle.


What's the anode connection on a gas water heater ?

I suspect our UK water heaters are a bit different.
