Hi,

Came down stairs yesterday morning to a nice brown mess on the kitchen
worktop under the boiler yesterday. I suspected the CH drain cock,
which is situated directly above the boiler, so I placed a container
under it after I cleared up the mess. Nothing all day (heating on and
running for most of the day), then this morning, there was about an
egg cup full in the container. It appears to only be leaking when the
CH isnt on or cooled down.

I did drain it down in October (and used the drain cock) and it has
been fine until now. I will try tightening it up a bit today but I
was just wondering why it has started to leak all of a sudden, any
ideas ?

Alan

It could be leaking all the time but evaporating when the boiler is on.

The washer could be damaged - or the seating dirty.

It could just have vibrated a bit loose, and expands when hot to seal itself
or - as someone else has suggested, the leakage may evaporate when hot.

Rather than just tightening it, I would be inclined to open it for a few
seconds to wash out any crud which may have collected under the washer - and
*then* re-tighten it.
