High Electricity Bills
•
Is the Pressure & Temperature Relief
Valve discharging too much water?
•
Is one outlet (such as the shower)
using more hot water than you
think? See “No Hot Water”.
•
Is there a leaking hot water pipe or
dripping hot water tap? A small leak
can waste a large quantity of hot
water.
•
Replace faulty tap washers and have
your plumber rectify any leaking
pipework.
