It is quite often that people have their air pumps located below the water level of aquaria and ponds. In such cases, by the action of siphon, water can actually be sucked into your air pump when the electricity is turned off. I’ve witnessed a couple of occasions where a simple, relatively inexpensive installation of one-way valves in the air line tubing would have come in handy.
As you know, water and electricity should not mix. The least of the worries is that you’ll have to replace the airpump and dry the wet carpet. The bigger worry is risking an explosion and possible electrocution!
So, if the set-up of your air pump is similar to what I’ve just described, make sure you go out and get yourselves some one-way valves now!
It will save you in more ways than one.
