Thanks for getting back to me with the explanation of the dimensions. Mine are, as you suspected 15mm. As for pulling the plastic cap off and turning the spindle with a spanner, I've done that and unfortunately it's the spindle that goes around indefinitely.

One point I forgot to clarify. I have a number of valves in the system which just turn and turn indefinitely. What does this mean, are they broken and if so, are they likely to be broken shut or open? Also when I'm looking to buy new valves at Screwfix I see 15mm x 0.5" or 10mm x 0.5"...

Thanks for the continuing advice guys. I've checked the exansion tank, and that's full of water so I'm assuming the pressure is ok. The water is leaking from corrosion from the problem radiator itself. Trying to shut this radiator down to deal with the problem got me into this position...

Hi Bacho, Thanks for the help. I went through all those last night. I cranked up the pump speed and shut all the raiators except the one I was interested in. I heard a lot of gurgling, but when this stopped the radiator still wasn't hot. On bleeding the pump I found I could take the...

I've got a leak in a radiator and in order to attempt to fix it tried to shut the radiator off so I could inject some Fernox sealer in. One value has a simple plastic handle which I removed and turned the spindle underneath with a spanner. This actually seems to go round and round for ever...
