This thread about PVC pipe has been beaten to death and resurrected again
and again! Short term memory loss??
I am by trade an industrial pipe designer with over thirty years of
experience in every chemical, pharmaceutical, petrochemical and paper mill
you can name.
I would NEVER use PVC pipe for pressurized air. It lacks physical strength
for impact resistance, durability and is subject to ultra violet
deterioration over time.
My home system uses 3/4" galvanized iron pipe with screwed fittings. I use
quarter turn ball valves. I have what is called a "dirt leg" below the
valves with a ball valve on the end for blow down. I have a ball valve

procured locally at Homey De-pot and such. Correct operating pressure dry
air and oiling for air tools will ensure long life and safe operation.
This the only way to do it safely.
