Ok here's the making of one of my largest posts.
I have 2 founts here, both Andale type. The Hoshizaki Lancer way of doing things is simmilar.
This first pic shows a brumby tap, lockin shank and adaptor (This system is very popular in QLD)
And assembled...
Now we get into the business end of the fount, Note the riser lines are a single line from top to bottom and are usually approx 2m long.
Top of fount assembled.
And with lockin adaptor inserted.
Assembled complete with adaptor, shank and tap.
Adaptor and tap with shank. Normally the adaptor remains on the fount and is only removed if there is a problem. The tap and shank are removed to rekit the tap when the O-rings wear out.
Retaining nut removed from fount. This nut is usually where the tap decals are mounted. If the tap decals are overtightened regularly then this nut can crack, making for an interesting glycol bath for the bar staff.
Adaptor, retaining nut and insert. Note the locating pins on the insert. This enables rotational force to be applied to the insert. The large black O-ring is what seals the glycol side.
Rear of insert showing riser line attachment. This one used an ferule insert that is pressed into the end of the riser line then the retaining coller is tightened up forming a seal on the end of the beer line. Commonly the riser line will attach to a John Guest fitting. Andale seems to love these ferule fittings. They do notthing but piss me off, dificult to work with.
Inside of the bare fount with locating pins that match the insert.
Empty fount, showing all the holes with no riser lines or glycol.
Another mic of the same thing...
From the top of a T'bar fount back to the bottom end.
Side on view of bare fount with no insert or retaining nut.
I hope that this post has answered more questions than it raises but there you go.
