Hi back again for advice I have just finished a Directors beer took a small glass out of the keg very nice and clear and tasted it very good. I wanted to take a pressure reading so got the pressure meter which is a Shrider valve it gave out a reading of 00. So I put in a gas capsule waited a few minutes but Nothing still 00 The beer look fine but concerned of what the meter was showing. When I followed the intrusions on here about keging it told me to just tighten the 4" cap hand tight is that correct or should I tighten more than that I was given a spanner with the keg by the way. Just to add on both my kegs I do not get loads of froth on them where before I tighten them as much as I could then that is When I got a lot more froth. My main concern is the beer going off if the is no pressure on the valve? Thanks
