Radiator question - please help asap!

[reggers]

Hi guys - newbie on the forum. I need some help. I have a plasterer coming in the morning to plaster my bedroom. He asked me to remove the radiator myself which I have now done. I bought two 15mm blanking caps from B&Q but only one of them fit (the thermostat side). the other side is bigger but lord knows why

I have a combi boiler and the radiator is upstairs (on same level as boiler). I do not plan on having my central heating on overnight but obviously planned on leaving the boiler on and not draining the whole system so we still have water.

The lockshield valve is closed as tight as I can get it. My question is - As there is no blanking cap on lockshield valve - is there a chance that it can leak overnight? I have no concerns about the thermo side as that is now blanked off

Please help quickly so I can either put the rad back on or sleep easy with it off

Thanks

Simon

If it's turned off tight and not dripping it will be fine left like that.

Hi mate. It's definitely not leaking and it is tight. You definitely sure? Don't want to have to get my living room plastered and electrics re-done

don't worry, lockshield ends are like taps- off and no drips will be fine until you want them on again.

Great stuff - thanks to you both!

Much appreciated

Also, assuming the system is sealed (you have a filling loop to top it up and this isnt open!), the worst case scenario is you'll lose the water in the system. Open vented systems (tank in loft) would keep filling (and leaking) until the supply was shut off.

Coz it is.
Some rad valves have 1/2" tail unions, some have 3/4".
