No Hot Water!

[Sir Tigger KC]

The motor whirs, but the position switch dosn't move.  I can move it by hand though....

I gave it a whack, but it's still not behaving.

I guess I'll have to take the head unit off and manipulate the valve by hand?

Why not just replace it? They're cheap enough and it's only a couple of compression joints and a bit of simple wiring. Just make sure you make a note of which wires go where.

Sounds simple in isolation. In reality it means water pissing everywhere and poor old Tigger's demise due to electrocution. 

At least it would be a quick end! 

And the Beemer will probably out live you M'lud!

This should be suitable!

Nine grand. You could probably get a plumber to do the job for you for that amount, what with living outside London.

Does it come with a free replacement BMW? Two birds with one stone...

a bit pricey at 9 grand 
i can sell you one including fitting for half that

At that price obviously a reputable supplier with 79.2% positive feedback on 14 sales.

Lord Opti would order a brace just to keep a spare one on the shelf, like he keeps the Signum as a backup car for his Indian made Oxford Ambassador.

I believe they still manufacture the Royal Enfield 500cc single. At least it can be fixed by the side of the road.

FTFY where it is an old British design.

This is more like it, a pattern part!

Cheapskate.

You do realise a pattern part will leak/break/both approx. 3 milliseconds after fitment,the system will go into meltdown,your house will blow up and you will die don't you?

At least it's only the electrical bit, so can't leak (anything other than electrons ) .. cheap 1/4 turn ball valves are nothing but a pain in the arris in my experience, they always manage to start weeping..

So it turned out to be the thermostat afterall....

Unlike you to keep it to yourself like that Uncle STEMO?
