Hi,
Have replaced the bath taps today (I'll get a plumber next time, but that's another story!)
Anyway whilst isolating the supplies to the bath in the airing cupboard (gate valve on cold supply from cold water cistern in loft to bath and cold feed to HW cylinder) I noticed another gate valve which on trying to turn was seized.
I thought "can't have that" and so set to freeing it with penetrating oil and a spanner which I did. Trouble is I'm now not sure whether it was in the open or closed position before I started.
I've been in the loft and the valve is on the pipe that comes out of the bottom of the "small tank" in the loft and so I presume it to be the central heating feed? I also presume it should be fully open?
Just for peace of mind can someone confirm I'm right? I assume it's use is for when draining down the central heating to avoid the need to tie up the ballvalve in the small tank??
I appreciate any replies to a likely numpty question.
