The Vetus water tank inspection lid WTK02 is a round hatch specifically designed for use as an inspection port for water and waste water tanks. It should not be used with fuel tanks.
This lid is supplied without counter flange or gasket, for installation into tanks with particularly thick tops - for most tanks, the inspection lid kit should be ordered, which includes a counter flange.
This lid must only be installed into the top of the water or waste tank. It is not guaranteed leak-proof, so should not be installed into the top of tank if the tank is connected to another tank above it.
