Nothing wrong with it yet, but just in case. I have an INDIRECT system. The valve itself sits right at the back left hand corner. I believe there should be a 'lever' on the unit (cannot see it), ??? is this for draining down, or will I have to manually drain down next to the boiler downstairs. I take it because the system is indirect the HWSV will not have to be drained, only the coil inside?? Newly Qualified, so NO working experience, so sorry guys if this seems a stupid question.

the lever is to lock the valve mid pos for filling and is usually the same end as the wiring enters the head
yes you will have to drain down from the boiler
yes
Thanks kevplumb. I know it possible to change the synchronous motor, but getting to the valve, is just too tight. It's on it's end (vertically) and facing away! When changing a motor, would it be safest just to flick the mains off before dismantling?
just a little
