What it is
The Glow-worm S801201 is a membrane cover supplied as a spare for Glow-worm heating appliances. It sits over the membrane inside the water section, holding the diaphragm in position and sealing the chamber so water is contained on the correct side of the assembly. The cover is listed under the standard water heaters category of Glow-worm boiler spares.
