PVC Pipe = Baaaad!


Um, so… I was talking to a dude at a haunt today about a drop floor we recently shipped them.  During the conversation he mentioned that they had installed 2” PVC pipe to run compressed air throughout the haunt … and it was exploding!

The lesson is that you cannot use regular PVC pipe and fittings from the hardware store to run compressed air through!  PVC pipe is brittle and will eventually blow out – especially if bumped into.

If you have a permanent (or even semi-permanent) location then it makes sense to have several big compressors feeding compressed air into pipes that carry a large volume of air to different major prop locations.  Traditionally this has been done using metal piping (such as copper or black iron).  There are now newer materials that can handle compressed air such as “thermoplastic” pipe which is safe and less dough.  I’m not an expert in this area and we don’t sell it so check with a local plumbing or HVAC distributor for more info. But please don’t use that white stuff from the hardware store!

Do you have experience running piping throughout your haunt?  If so, leave a comment and let us know what you used and how it went!

    I don’t see why you couldn’t run the plastic DOT line that they use for tractor/trailers. We sell it at my work from 1/8″ all the way to 3/4″ and it’s rated over 200 psi. The thing that will get expensive over time might be in the fittings.
