AIR PUMP CHECK VALVES - Do you really need them?
Ғылым және технология
How does check valves work? The manual say that you will need a check valve if you place your air pump lower than the aquarium or reservoir. In this video we try to find out by simulating power outages to find out if non-return valves really are necessary?

Thanks, this clarified why the siphoning happen. Its because of air bubble that pulled the water that normally would not go above the surface level.

Yes, we think this is part of the answer too :-)
This just saved me from freaking out at 1am with no pet store open for a check valve lol
Thank you for doing this experiment! It was helpful. Please make another one with a sponge filter. It will be interesting to see.

Thank you very much!
U are using an air stone that has little chance of water entering. An open access pumping device has a greater chance of leaking. Just put a straight water hose in the tank and it will leak if the pump is lower than the tank

I understand what you mean, I guess it will leak easier without any air stone, , but the water still has to get over the tank edge. Also I wanted to test with the air stone I was going to use :)
You have forgotten that the line could be disconnected from the air stone. Or that the water doesn't flow through a air stone very well. But if your line is connected to a sponge filter or under gravel filter the water will back flow very easily.

Thank you for your comment and information about this👍 We have never tested with spongefilter or without airstone, but good to now😃
I am here to tell you the air line kept coming off the pump and no water was siphoning out. I didn't worry about it and eventually the air line came off and started pulling water out of the tank. Good thing it was caught during the day and only a small amount was in the bottom of the base. Yes all, it can happen. It happened to me it will happen to you eventually.

Thanks for sharing your experience😊 It is a good point that this might happen if the airtube shakes off the pump several times.
why dont you put pump higher water level?

Sometimes you may not have a place to put it that is higher, for example if you have an aquarium on a table its easiest to put the pump on the table next to the aquarium. But if you have somewhere higher to put it that is the best. 😀
If your power goes out that much you shouldn't have fish

Haha 😄 I see what you mean, but other stuff than power outage can happen...for example the air tube shakes loose from the pump, or you move the tube around in an unfortunate pattern while the power is out....but you have a point though...poor fish 😀
