Jumping in to home brewing with both feet, I decided I was going to convert my old Kenmore single tap kegerator to hold 4 Corney's of home brew and dispense all 4 brews at one time. Problem was I had a single draft tower and very little cash to spare.
Hence a home built tower out of 3" PVC pipe.
I used a toilet ring for the base, I just cut it down with a jig saw and then sanded it smooth. If I could do it over I would have screwed the base under the particle board top you see and just cut a bigger hole in the particle board top and made the tower taller. But live & learn!
First attempt. I bought a stick of 3" black sch 40 PVC pipe. My first attempt is below, just a basic 3 tap tower. Yes there are three staggered holes, one high on the left, one middle center, & one low on the right. I installed this & it worked fine, it just wasn't 4 taps, and I would never be able to get a drip pan to cover all three taps.
