Got A Compressor

The problem you run into with the electric solenoid type drain valves is the nasty brown rust/crud that comes out of the tank along with the moisture and they clog up easily. So you have to install a filter ahead of the solenoid valve to prevent that. Then you have to clean or replace the filter occasionally. Then if you ignore doing that - as my previous employer did, you end up with a 150 gallon water storage tank because it wasn't actually draining when the timer went off to open the solenoid.

Now how did that happen? We put an automatic drain on it!???
