How much insulated tubing do you think it will take to plumb a 2-door garage kit?
This house was built around 1970 by my brother for a Texas oilman on a riverfront lot. He liked his beer.
The first thing is you need a walk-in cooler like the butcher shops have or at least enough refrigerator to cool two kegs and with one being tapped.
The plastic line and fittings are available from your local plastic supply house. Similar to plumbing your refrigerat for automatic water and ice cubes, but a smaller diameter. It needs a very small inner diameter, because even with insulationn it will still warm up so you want as little residual beer in the line as possible.
He had the good sense to put the house in his wife's name as the oil business has a habit of bankrupting it's adherents from time to time.
Sorry for the double post.
