I had a siphon situation this week! Drained 80% of my tank in the middle of the night. Luckily the tank was still cycling so no fish were in there. I’m putting in the check valve!!
It doesn't matter if your air source is higher than the tank or not if the line disconnects at the air source and drops down behind the tank then you have a siphon condition. I've had an aquarium set up for 40 years and never used a check valve but just redid my entire setup and I'm gonna use the check valve just to be safe. Nothing like finding a 125 gallons of water on the floor in your family room when you come home. Just to be on the safe side just have my floors redone and I don't want to have the redo a memory place all the hardwood. But to each his own .for all the 40 years that I've had aquarium setups I've never used one and have gotten lucky but this time for some reason I'm going to
So you are a youtube certified aquarium architectural engineer who has never one time used an aquarium check valve but now after FORTY YEARS you decide to use one for the very fist time knowing you "don't need it" just to be safe 🤔..something sound fishy 🤓
I was looking to find if these valves slow the airflow down, didn't find it here. You talked stuff I know already but I had to watch it all because man, such amazing setup! Nice video!
I just setup my sponge filter system. I put it together without the check valve at first. Then cut the line to add the check valve. Absolutely no airflow difference
4:00 Thank a lot for the info yes yes you give me the idea now and i bought new aquarium co2 generator cylinder and it will be down the aquarium , i will buy the Check Valves now 👏👏👏👏
I have such a hard time with these! I've tried out like 6 and once it's installed, the sponge filter stops bubbling so it's not working. I'm frustrated. I want to be safe, but I want these things to actually work. It's like they do work when I blow through them but on the pump they just don't. And yeah they're facing the right way.
Bunch of air pump manfacturers will not replace or repair an air pump these days if you did not install a check vavle and it gets damaged by back flow. Tetra says it clearly in its infomation "Water damage does not fall under the warranty. So make sure you are using a drip loop and in-line check valve" same with fluval and aqua one
i'm a noob and this video helped, BUT I want to add, how many people have setups like you? by that i mean pumps in normal households will be below the aquarium, we don't have shelves like you, you have shelves so you can have more aquariums as you are probably running a shop, normal households have eg a goldfish tank on a table/stand and we have no place to put the air pump, its not a shelf where we can rest it beside the tank thus it goes on the ground level p.s why don't you put the valve on if it makes no difference, wouldn't hurt
Hey sir nice video as allways sir.. it's only in the pump end outside aquarium it's dangerous. inside the air pressure still pumping if it's disconnect from filter :)
I understand the reasoning for a check valve, but what is supposed to be supplying the force to move the water up and over the edge of the tank to start the siphon? Is it a vacuum in the pump? Pressure from the tank side? Does it only happen to people that have multiple devices connected to one supply by the use of T fitting? I was a plumber by trade so the why is more important to me than any anecdotal evidence that it happened to someone; I know it CAN, but why is it happening? There is a better way to defeat siphons than an in-line check; adding a T to air line above the water line and installing the check backwards so that it stops the flow of outward air but allows air in if there were ever a vacuum from the supply side (making it a mechanical air admittance valve) is superior in that it reduces the amount of resistance in the air system, thus increasing flow and reducing wear on the pump. If it is pressure from inside the tank somehow, the only way to beat it is to use a check in the system before the pump (or elevate the pump) to prevent the siphon from ever being able to start.
It will happen if the pressure of water in the tank is huge because you may have a 200 gallon tank or big enough and your tank is filled to the top close to the airline tube and when the pump is shutdown and the water rushes into the pipe and the momentum may cause the water to go over or travel over the water level and syphon into the pipe - this won’t happen in small tanks because there is not enough pressure!
@@sikandernuruddin9214 It doesn’t matter if it’s a half gallon or 10,000 gallons. The head pressure of the water and the momentum which comes up the tubing, and the rise to the top of the bend in the tubing are the only factors. If there is an air stone installed on the end of the tubing, it will never be able to rise fast enough to overcome gravity because it can’t move fast enough. It would have to be a combination of a tank filled all the way to the room, some kind of device that has unimpeded flow into the tubing like one of those little treasure chest things, and no needle valve installed on the line restricting airflow. Even a needle valve would cause back pressure against the rising water; as the water speeds up and goes up the tubing, the air would compress and provide increased resistance.
@@liquidrockaquatics3900 The assumption here is the pressure in the airline tube is none as the air pump shut down or the airline tube snapped at a connector - all you have to do to understand this is take a soda bottle and shake it and then remove the cap to know what pressure can cause the soda overflow or jet outside the bottle. - not all pressures cause the same momentum ..likewise with aquariums!🙂
@@liquidrockaquatics3900 Also, there is the pressure of the weight of the water 💦- try holding down an air filled ball or tube in a swimming pool 🏊♂️ and release it from various water depths!
I set my air pump on the tank lid, so it isn’t an issue. The likelihood of having a back siphon through the pump is low, and I am guessing it is from overheated pumps that stop, then the cooling air causes a vacuum. Purely a guess, but my plumber’s intuition says that it takes. Lot of bad coincidences lining up to cause a catastrophic failure. I’ve tried flipping the power strip and causing a sudden stop on my system over and over, and never once has there been any rise of the water in the air line the past about an inch, and that was on a sponge filter before I installed an air stone inside. The water rushing back up from the sponge and displacing the air didn’t have near enough momentum to carry it up and over the rim of the tank.

Absolutely important. Put ours in the wrong spot and now have water leaking through to our main floor. Fortunately unfortunately only about 10 gallons
Thank you, I finally found out what those valves were for...

🤟 rock on hand point. Love it. 🤟
Cool vid. Thanks bud. 🤜🤛🍻
What's your light bill run? Thanks for the video.😃
Awesome information thanks 🙏
Thank you. Explained simply and very well. Appreciated your personal experience and opinion, too.
Thank you for your help and I love your videos 😂

Thank you!
I put in a check valve for my volcano bubbler as I can’t have the pump above the tank. Now it’s restricted the flow. Is this normal?
do i need to make sure all the tubing is high to or is it ok to have some tubing fall low

👍
ive unplugged my airline 100x times and never had it siphon once how would it siphon at all?
Just happened to me…. 20Gallon take, lost 10gal just while I was in the shower
Nice room
So if you are going to use the safety valve can you hide it under gravel or you install it outside the fishtank?
Real question
Can go anywhere on the air line, even right next to the air pump
Answering for future people. Do not put the check valve under water. It should be halfway between the sponge filter and the air pump
The words you are looking for are backflow prevention.
Would love some shipped to MD ! Need some water lettuce any one around and sees this comment please lmk

@@sikandernuruddin9214 ignorance is bliss. An aquarium is not pressurized it has nothing but atmospheric pressure pushing down on the water.

Also, there is the pressure of the weight of the water 💦- try holding down an air filled ball or tube in a swimming pool 🏊♂️ and release it from various water depths!
I'm a bad girl lol I have them, do I use them..nope lol. Maybe this is a sign I should... 12 tanks so the odds are against me.

You make complicated explanations.
You really are drunk damn. Didn't understand this chaotic video.
