we do test those in here..And let me tell you that we have a LOT of them...
its so damn cold here sometimes..

The only problem with air filled sprinkler, is that you need an air
compressor for them to work properly, and that can be cost prohibitive..

And now that we have sprinkler that use plastic tubing in residential
building ... under air pressure I am not shure it would last long...
