Thank you for the thorough explanation and for sacrificing a valve to show us the inside. Didn't realise I could run the pump without the valve if I put it in the right position. Unfortunately I don't think I can move my pump to above the aquarium but that is good to know for future troubleshooting.

as a newbie i had no idea that this was something that was important to consider and I thought that valve was to connect it to multiple things so i threw it away 😂 im glad I am a nerd and spend my free time watching tank upkeep yt videos otherwise I never would have known! putting my pumps above my tank as we speak!

I have a battery operated pump. The battery ran out. I opened the back to put more batteries in and it had a lot of water in it!!! Where I placed it, was almost up to the ceiling, way higher than the tank, so I advise everyone to put it on their pump. I just came here to be sure which way to install it, cuz mine only says, Up or Down, Lol. You explained it very well, God Bless! 👍

[@pentatonic7833]

Really? Water that high? I run them but was thinking of putting it about 3 feet over the tank without a valve. It doesn’t make sense that it would flow up. Was it down before and maybe water got in them then?

[@markvillanueva5660]

Thanks man it was kind of surprising that whenever using check valves could actually reduce the output and air pressure so amount of air is technically reduced.That was quite clear to me now and I even got one of these check valves just for stopping the water coming up to the hose and clog the airway but it seems that purpose is not working that way I don't know why but it shows I couldn't get any help of it so I'll just get rid of it.I just wasted half a dollar cheap check valve but saddest thing is when this is what and how they really do, minimize the air flow.

[@TrafishAquatics]

Yea for sure, that's one of the reasons I ended up switching to a central air system.

[@MsLila44]

Just have a long airline.. similar to the drip loop for electrical cables around the tank. gravity is even stronger than a valve and won’t reduce the airflow.

It has happened to me one time in the past when an aquarium was extremely full of water and we had a power outage. When the power came back on I noticed that there was water coming out of one of my air pumps, but this was a few years ago. It's an extremely rare occurrence but it does happen.

[@pamslove]

i'm wondering if using a small hook to secure the air tubing in an arch, placed higher on the wall behind the aquarium would work as well? No room anywhere 'above' to place the air stone pump.

[@TrafishAquatics]

Yes it would

[@WhoopiCushion]

What if I have a 10 gallon with a small pump and a dual split check valve running one small stone and one 3 inch stone in one small aquarium. Wouldn’t that be more efficient then the one 3 inch stone I would have to run if I didn’t have the split check valve even though it’s at full power.

[@TrafishAquatics]

If you have one line that you split into 2 the air pressure will be cut in half to each line, once the stones are added the air will self regulate to follow the path of least resistance, if one stone has smaller pores it creates higher backpressure and forces more air to the other stone, if you want to run 2 stones its best to get a dual outlet pump.

[@TheRealKirkHammett]

thanks for this video. I needed to know how these worked for my air pump and whether I needed it or not.

[@TrafishAquatics]

You're welcome

[@greysunshine]

Hello, I have a PowKoo bix corner filter. It has no air stone. Is there still a chance that a siphon will occur in a power outtage? Also, I've heard that they can help airpump last longer. I am very confused.

[@TrafishAquatics]

Air stones are not required for these, and airstones can actually slightly reduce pump life because they add backpressure to the pump when the start to clog up

[@maxpowerdj]

Thanks for your video. Where do you get your valves? I've been trying to get one for a bubble wall application that needs to handle a lot of pressure since the pump is underneath the bubble wall. I know you work with aquarium stuff, but would appreciate any help for a vendor or a specific model of a check valve that could handle the pressure. Thanks in advance!

[@TrafishAquatics]

What kind of air pump are you planning on using?

[@TrafishAquatics]

For any air pump, that uses standard airline, any standard check valve will work essentially the same. The ones that I reviewed in this video came with my tetra air pumps so I just have a bunch of them on hand.

[@kamleshdhruv5217]

There is one more advantage of air check valve. It helps increase lifw span of air pump. Because each time air pump is turned off for any reason, the water flows into the air tube all the way upto the hieght of water level. And each time you turn on the air pump, the air pump has to work hard to push the air through the tube, to get the watwr out and then flow of air begins. This resistance it builds, reduces life span of the air pump. Hence , this air check valve is really good and a must have. I would suggest using it inside the aquarium, because it will have least resistance. If you install it upwards it will have same issue, as it will have to force the water all the way before ocygen continues to flow out of tube.

[@do1du]

[@TrafishAquatics]

No there's 2 things happening that I can see, there is a pumpkinseeds with a peice of shrimp that shows it's reflection behind the sponge filter. The other in the very bottom left near the substrate is a reflection of one of my Tamasaba ryukin goldfish in the 55 gal behind the camera. Good eyes though I never would have seen that lol

[@mel--kie2799]

I take your point about the air supply being restricted and the pump must work harder. Is it significantly more difficult to blow through when blowing harder/faster than blowing slowly? Could you make an inverted branch of air hoses and put a check valve on each of them, so the pump is not working so hard to push air through one narrow opening, but pushing a the same amount of air through multiple opening in multiple check valves. eg, a branch with 3 check valves?

[@itsalexism7047]

[@harry.s5385]

I use Aqua one check valves. However some of the new ones I get don't work! (I have already tried putting them both ways)

[@TrafishAquatics]

Sometime the little rubber boot inside gets gummed up and won't open to allow air to pass through.

[@harry.s5385]

I managed to get it working by popping the seal in the test valve. Nice video!

[@TrafishAquatics]

Thank you I'm glad you were able to fix it

[@GrayWolf420]

Yea I have one with one of those but the stone isn't working anymore idk why

[@TrafishAquatics]

traditional air stones can plug up over time and need to be replaced every couple months, the excess backpressure can cause damage to your air pump too.

[@GrayWolf420]

@@TrafishAquatics hm well I replaced the hoses and cleaned both stones there working perfectly now

[@TrafishAquatics]

That's good, they must not have been clogged too bad then

[@Camandthings]

Are they safe to use with a co2 system? Fluval 45g? 1500psi?

[@TrafishAquatics]

I wouldn't use these I would get something specifically made for CO2 systems as CO2 has a tendency to degrade rubber

[@Camandthings]

@@TrafishAquatics thank you !! Will definitely be looking to upgrade when I can

[@mel--kie2799]

Is there another style of valve, it looks like the check valve you held up, but inside we find a white plastic ball, that floats and plugs the air line when it doesn't pump, but as soon as you turn on the air the ball is pushed down and away from the high point of that plastic chamber. It doesn't matter which way you install it because the ball floats up as the water back flows into the plastic chamber.

[@stefaniep4374]

I have my pump on top of my Aquaclear filter, does that mean I'm in no danger of back siphoning in the event of a power outage thus don't need a check valve?

[@TrafishAquatics]

Correct, it wouldnt be able to flow up higher than the top of the tank, the reason why an air pump under a tank would need a check valve is if water flows up over the top and starts to go down the other side it would create a syphon, if the pump is on top of the tank a syphon can not be started

[@stefaniep4374]

@@TrafishAquatics thanks! That's what I thought as far as the laws of gravity go, but I've never used a pump until tonight so wasn't fully sure exactly how they may or may not be capable of somehow interfering with the normal nature of gravity.. I keep having people in my fish groups tell me to add a check valve anyway? But that didn't seem to make much sense to me .

[@TrafishAquatics]

Yeah if the pump is above the tank you don't have to add a check valve, if it's below the tank I would consider adding one. In the future of the channel my fish room is going to be getting rebuilt in a different part of the house and I'm going to be running a central air system using a linear piston pump and PVC around the room hanging from the ceiling and with that system no check valves are needed because there's no way for the water to siphon uphill

[@aave865]

Do I need one for water pump?

[@TrafishAquatics]

Depends on the setup, For example if you're running a barrel filter full of k1 media and your power was to turn off you don't want the k1 media to get sucked back out into the pond or whatever your filtering so you would want to check valve in that sense, but if the water's just going to flow from a waterfall feature back into the pond it doesn't really make a lot of difference.

[@aave865]

@@TrafishAquatics thanks ! I am using it for waterfall and has been wondering all these times if I should get one check valve.

[@TrafishAquatics]

Probably not necessary cuz when the water back feeds back into the pond it doesn't go anywhere except back to the source
