I had a batch of circuit boards in my AP bucket. I needed the extension cord for another job I was working on and unplugged the air pump for all of 5 to 10 minutes. When I came back, the AP solution had siphoned from the AP bucket back up the hose and into the air pump. I then hosed off the air pump and blew a slight breeze from my compressor into the inlet filter to dry it out. Plugged it in and no air. I thought the check valves inside the air pump should have prevented the AP solution from back flowing into the pump, but it didn't.
Fortunately these pumps are really inexpensive, but in the future I will make sure I have an additional check valve inline and place the pump in a location higher than the AP bucket. Hope this helps others.
