I have a Jaga Iguana Aplano radiator with the Iguana Angled Wall Mounted Valve, fitted in 2008. I don't know if the valve is fitted in two pipe or monotube mode and I can't get a view behind it to find out.
I now have a leak from one of the tails from the valve to the radiator, because it looks like the idiot who fitted it did not tighten it properly into the radiator.
I've tred to tighten it with water pump pliers but the collar is just spinning, So I assume that the collar just sits on a shoulder on the tail and serves as a flat face for the fibre washer?
The radiator needs to come off so that I can tighten the tail properly. I obviously need to isolate it, but cannot find any instructions on how to do this. The radiator mounting instructions PDF on your website seems to indicate that with one port closed, the other is still 10% open, which worries me a bit. Is this still the case if I take off the thermostatic actuator and use an isolating cap? It is a big system so I don't want to have to drain all of it down just for a pesky radiator leak.
Can I completely close it off by using an Allen key in the adjuster on the opposite side to the thermostatic actuator? If so, which way do I turn it?
Also, if I need to replace the tail, is this a special size or can I get a suitable item at a plumbers merchant? It looks rather bigger than those on all my other radiators.
