Tired of dealing with rigid tubing and sick of trying to clean the inside of my blow off tubing, I'm considering making a rigid blow-off. My plan is, from the carboy: 1" ID vinyl hose (3-4") to a 90-degree CPVC elbow to several inches of straight pipe to another elbow and more straight pipe down into water/sanitizer. I'd use slip joints and no glue so the pieces will be easy to disassemble and clean. My only concern (and not a big one) is that the slip joints may not be tight enough to keep out contaminants. Assembling the unit while its damp with sanitizer may be adequate. Anyone use a system like this?
