The Snap-on Air compressor by Big Red Air Machines is getting an updated automatic water drain valve. The old unit uses an pneumatic actuator and two ball valves to release air and water from the bottom of the tank. It has worked great and has only been replaced once in the last 15 yrs. this part is no longer available and instead of sourcing the parts to rebuild it we decided to upgrade it with the new simple version of the automatic water drain valve.
