First mistake is trusting grainger for advice. Better luck asking autozone about aircraft engines.
Draincocks get plugged up all the time and you need to remember to open and close them.
Look what I posted above. They are used on reefer trailers and containers.
Zero maintenance. Never mind cheaper.
