Hi All
Haven't tried my stopcock for a while and it won't turn by hand, tried a cloth over it
Any tips to get it moving please
Many thanks
Phil.

Safest to try this after turning off the water in the street to avoid a possible soaking.

Penetrating oil and leave it overnight

see if you can back off the gland nut a little first, only a touch, then try the tap.

Would wd40 be ok ,if not what penetration oil do you recommend please ?
