During your tank inspections you should ensure your heating storage tank is waterproofed. You should check the lid is securely fastened, and also check for any signs of damage where water could seep into your tank. After heavy rainfall you would be advised to make an unscedules check on your tank, just in case the weather conditions have adversely affected the integrity of your tank.

If water does get into your fuel it can cause the growth of unwanted bacteria and the formation of sludge at the bottom of your tank. These can cause many problems if they then enter your fuel lines. If this happens you will need the assistance of a Heating Engineer to flush the pipes to return the tank to working condition.
