Water tanks should be checked annually for corrosion if they are made from either stainless steel or aluminium. It is worth checking the hose connections and the inspection hatch seal at the same time. If the tank can be removed easily then it would be worth checking the underside as well if it has been in contact with salt water. Check all straps and fixings for security and tightness.

Wipe the tank down with a damp cloth to remove any dust or dirt. Flush the tank with either a Milton solution or AquaDosa Sanitiser and then re-flush with fresh water and then empty. Leave the tank empty over the winter period to prevent the water freezing and causing other damage.\
