Air pump above aquarium?

I just ordered a bubbler and air pump. The website stated the air pump needed to be a foot above the water level. Is this true? I also bought a check valve to ensure water can't siphon back into the pump. Thanks

 

I've never heard that the air pump should be above the aquarium. Mine is underneath my aquarium but I made a loop (down and up) with the electrical cord so just in case the water leaks and follows the cord it doesn't leak into the outlet. If that makes any sense.

 

only reason I could see is maybe worrying about a syphen happening? or would having to push air up and into the tank lower the output perhaps?

 

I have 4 air pumps all below the water level with no problems. that check valve should stop water from coming the wrong direction.

 

I've had an airpump under my tank for almost 2 years. I haven't even done anything special with the tubing.

I haven't either, do you use a check valve?

I leave mine running 24/7 so only in a power outage could there be a problem. that is what the check valve is for.

 

I figured that info was a crock of bull. Thanks for confirming.

 

I don't even have a check valve. I never use them lol.

 

I am a strong believer in Murphy's Law so I opted for one lol.

 

Alot of gang valves have check valves built in if you are interested in them.

 

Good morning,

It is highly recommend that you keep the air pump above the water line. If not and you have a power outage, then water can siphon through the air tube and cause a flood and or possible electric shock when it turns back on. Keeping the air pump above the water line will prevent this from happening.

If you do keep your air pump below the water line then please add a Check Valve in the link below. This will prevent the siphon/flooding:


You should be able to find the Check Valves at your local fish store.

Spending $2.50 can save you a lot of heartache!

Drip loops are always good for all of your equipment but this will not prevent a back siphon/flood concerning the air pump.

Yes, check valves will save you a lot of headache! Get the for any air pumps you use, even of you keep them above the water line.
