Leaking radiator valve

moneyuser

Decided to turn the hall radiator off as it was getting a bit warm. Valve was a bit tight so applied some force and then it started leaking. Now have no boiler pressure and no hot water or heating

Will be calling someone tomorrow but have been googling to see if I can fix it myself but not even sure what type of valve this is. I can't seem to find anything that matches the images below. Is the nut I've labelled "Unscrews" the gland nut? If it is, what is the one called underneath it, labelled "leaking nut"? This one will not tighten up.

Is it fair to say the whole valve will need replacing? What charge should I expect for this?






Thanks

If you have 2 spanners to gently turn the two nuts it should/might stop leak......you might also need a bigger spanner/molegrip to hold the big vertical nut on left

Only the top one tightens. Not 2nd one

Wookey

The top nut is the packing gland and is the most likely source of the leak, the constant turning of and on of the valve means these all leak over time. Removing the gland nut and repacking in below it before replacing the nut should stop the leak. If it is the second nut that is leaking and a slight tighten of it isn't curing it then i would be inclined to replace the valve. Those are a basic fairly cheap rad valve and paying someone to drain down (or swap it out whilst live) the system and spend time removing/resealing the body opposed to just replacing it is the cheaper/quicker option. It may also be worth considering replacing the valve with a TRV which will turn itself of when it gets a "bit warm" in the room.

If you have a combi boiler then the rad valve leaking will have dropped the pressure in the boiler,check the gauge and make sure the pointer is in the green,boiler should then fire up.

I can re-pressurise the boiler but that just makes leak worse, resulting in overflowing container which is not what you want to find when getting in from work.

Have someone coming on thursday so will have to make do until then.

Thanks for yhe suggestions.
