Love how you repurposed the piano!
So my bus was owned by BrewDogUSA -- not so common here but very common in your neck of the woods I hear!
I'll be doing a bar-bus as well -- if you have details on the plumbing set-up somewhere please post a link.
I'm assuming with 4 taps you've got a proper kegerator with CO2 and not a "jockey box" set upĒ
Hey yes brewdog is very popular over here, PUNK IPA is sold in most places, itís great if you havenít tried it.
We opted for a EVO-70 cooler, which allows us 4 kegs. So you have your CO2 lines going into the kegs, which pushes the beer out of the kegs into the cooler, that goes around a cooling element which then goes to the beer taps.
The EVO70 allows you to put output tubing cooled water too, so we then tubed up 4 lines which we wrapped around the beer out lines that go to the draft taps, we cable tied these around the beer line and insulated them with foam wrap. which is acting like water cooling for the lines.
So if you are a long time down without serving a beer it means the beer thatís in the line up to the tap will stay cool and not spoil.
We wanted to try and keep a more traditional set up.
Iíll try get some better pictures of the set up for you this weekend.
