Size of a radiator valve on cast iron radiator

[dominoman]

Does anyone know what size this valve is?

Which part should I measure?

I'd like to buy a fitting that would let me attach a garden hose to it to flush it out, without taking it to the garden. Too heavy...

Thanks

Take the tail out of the rad and take it to plumbers merchant to offer up to fittings. Once you have what you need, reattach it to rad valve

That rad looks heavy, whatever you do, don't drop it off the brackets or you'll never move it.

Looks like it`s lying on the floor already , Rougetrader

This valve should fit onto that tail. (I think!)

Just connect the valve to the tail. Then use a short length of 15mm pipe and a jubilee clip to connect the valve inlet to a hosepipe

I'm going to get one of these jobbies and see if that fits. Then I can flush it without moving it any further - which unfortunately is not an option...

Like most radiators it has a 1/2" female connection. The brass nut and tail currently connected will need to be removed and most valves will fit.

I think it's bigger than 1/2" though. Which part do I measure? The outside of the thread on the valve?

If you are wanting to connect a fitting onto the current radiator tail i think the nut is 1 inch bsp. You were on the right track with the previous post. You will need a 1inch male threaded fitting. But you could also just use the valve i suggested as well.
