Hi Stuart,

Almost certainly you don't. If there is a float valve in the header tank then yes you will, but there alomsot certainly won't be one.

This means you'll be fine to drain down without turning OFF the water, but you'll need to rig up a hose pipe or some other method of manually re-filling it after changing the heater element.

Cheers, Mike

Crack open the element

While the tank is full, crack open the element. But wait! open so it turns a little, do not open it completely. This will help prevent the cylinder from folding in and damaging.
