Yes, I have had this problem with my beerspheres.
The tap is not at the bottom, so it needs pressure to force the liquid out.
Basically I don't think simple compression (parallel to the axis of
rotation) is enough to make the O-ring gas tight. Unless you are
exceptionally strong tightening it up.
I reckon the O-ring needs wedging to get enough compression with
hand-tightening. That is, it needs to be trapped between two tapered
surfaces.
I get round it by giving it a short burst of CO2 before each supping
session.
It loses pressure over 24 hrs, but I guess it stops leaking as the pressure
goes down because my cider does not oxidise (from air let in).
Gas also leaks from around the tap, so that needs to be really tight.
IMHO I don't think Hamilton Bard products are that well designed. |
