Rated 2 out of 5 by I've been through a half dozen of these things. I cant seem to get more than a year out out of em. Yeah at 100$ they're about the least expensive unit available. In my opinion the convenience makes it worth the expense. August 23, 2013

Why doesn't ilt work.

I have tried both the alt method and the pilot method it still does not dump the system . I have had a 30-35 psi change a 40-45 psi change still not dumping. I have tried a fast dump and a slow dump of air and still no dump.
It is used on a tank hooked to a 30 HP air compressor sometimes the air drop is fast (3-6min) and other maybe longer due to the demand on the air. The tank sits outside so can not use an electric drain valve.
I need to know why it does not dump on a 30 psi change can you give me help to get it working. It was delivered yesterday and installed today. The pressure on the compressor is set to load at 97 psi and unload at 126 psi. the drain does not work at any time during this change of psi. The capacity of each tank is 250 gal.
