Hello All
Now and then we get a loud (sometimes VERY loud) humming noise when we run the hot tap (seems to come from the loft where the tank is). We have an economy 7 immersion heater (if this is at all relevant), and no central heating, so no gas boiler or anything. Is this likely to be anything serious that we should be consulting a plumber about? any ideas as to cause welcome and any advice much appreciated - we are not well off and any financial outlay is going to hurt badly, so am sitting here with crossed fingers! TIA
