I have had three of the Harbor Freight drains and never got one to last more than 6 months. They plugged up and stopped draining or cycling when the compressor started.
Iinstalled a timed electric one ... every 45 minutes is the longest interval it will allow with about 2 seconds being the shortest drain burst ... about $100 and available from many places.
I don't do anything to clean or maintain it and it still works but I've only had it on the compressor for 3.5 years so ...
