Leaking mains stopcock

[keith2511]

The internal stopcock was closed for the first time in about a year as part of a bathroom installation. Now that it's open (I leave it a quarter turn from fully open) it has a slight leak, approx half an egg cup full in 24 hours. Should I get it replaced?

Thanks in advance.

Probably just nip up the gland nut.
