Turning off hot water - (water cylinder)

[sotal]

I have a water cylinder in the airing cupboard.

I'd like to turn off the water supply to the bathroom.

I found the cold water supply pipe (from the tank in the loft) straight away and turned off the tap on it.

I think I have found the tap for the hot water but it didn't have a tap end on it, so I took the one off the cold but I can't turn it. Is there a way they can be locked in place or has it simply seized?

Any tricks to undoing it without snapping something. Access to it isn't great. It is in the back corner of the top shelf in the airing cupboard.


Just to confirm I have the correct pipe... It comes through the ceiling from the loft - goes to this tap, then continues down to a T piece. One side of the T comes round to the front and just has a drain on it, the other side goes into the back of the cylinder near the bottom.

The taps look more like gate valves but rather than having the wheel they have a brass tap bit that fits on - looks like the tap should have a screw to hold it in place but didn't so I was able to just pull it off the cold to try on the other one.

So first - am I trying the right tap?

Second - how do I turn it if it has seized?

Thanks

Sounds like it.

More force. Although they are prone to snapping - especially when closed Better to just drain the storage cistern down and the fit a new valve if you want to.

Thanks,

Due to lack of space I would have to dismantle the airing cupboard to replace the valve!

I managed to spray some Shock and Unlock on it which works for stuck bolts. First try and it still didn't budge but after the second try it started to move. All free now and working - it was the right one.

Thanks
