Hi

Can anyone advise something that is good for loosening stiff stopcocks, bolts etc. I do not want to use WD40 in a water system for obvious reasons.

Many thanks

Paul
 
I've got a crow-bar and will be happy to lend you it.
Alternatively, fire up your blow torch and apply heat to the stopcock, then whack it with a sledge hammer. That will loosen it. Works all the time

Seems like a strange question. Big pump pliers and some common sense.
 
dont know if anybody else does this but id loosen the gland completley first if really stiff, then just play around with it! i use a big pair of pump pliers if its accessable, otherwise ive got a bit T bar that usually solves it or snaps it!
 
You can buy short mains stopcock keys which are superb for snapping the handle off.

You are right, slacken the gland nut, no matter how long it takes! I scrape the spindle with a knife, then slacken the packing nut with a shifting spanner while holding the head from turning. Then use grips to pull/turn the packing nut back off & scrape the bit of spindle you couldn't get at. Dab of Vaseline or silicone grease & all back together nice & freely turning!
