Agile - what can i say? It never occurred to me that the valve may not be working and to try that test but now on reflection another test I did may have incorporated that most basic one.
On Wednesday I switched off the two gate valves I put the motorised valves into the manual closed position too. One by one I released them when the boilers heated water reached them. One by one the valve body then the pump casing then the next valve all heated too hot to touch. Then the hot water reached the motorised valves. I waited for a while to ensure the heat wasn't getting past the motorised valve bodies to the pipework beyond, before releasing them too. Would this incorporate the test you have just mentioned, do you think? If not I will try that test.
I wonder if any of you have ever had any dealings with a suppliers called 'UniquePlumbingSuppliesLtd' out of Eastleigh/Hedgeend? Amazing they are doing a WILO GOLD 50 for £27-ish. I could just use the head. I would rather use a 'known' name though but the one I had in mind 'Screwfix' only stock WILO GOLD RS 50. I would worry about fitting a whole pump or creating a Frankenstein pump. Maybe the RS is just a minor electronic mod....?
Thoughts anyone..
