Video showing how a pvc overflow works. Also shows cost and gph of each size of PVC. This is a great alternative to drilling your tank, or paying for an expensive hang on the back overflow.

Have an issue? cant get it to work? HERE IS THE FIX: I have been answering questions on this project for years now.. and no longer will. Its the same answer again and again… the #1 answer that solves 99% of all issues is this: PAY ATTENTION TO THE VIDEO. 99% simply do not follow the instructions or build it the same way, yet expect it to still work. The other 1% have an air leak somewhere. Find it. Seal it. Sorry, but i simply do not have the time to keep answering the same questions, when they all result with this same solution. IF YOU MUST get help, POST A PHOTO to my fan page so i can at least SEE what the problem is. I will not be able to help otherwise. https://www.facebook.com/UaruJoey

Not only do you tell us how to build it, you explain how it works in great detail. You are the man. Thank you so much! A+
I am watching it in 2020 . Near to 2021
Wow how far the quality of your videos and they way they are delivered have changed lot less scripted never a less still fanatic footage 👍
Good Explanation..thanks a lot man..
I get 10 feet of 3/4” PVC for $4.28. It’s $2.14 for a 5 foot stick. 1/2” is a little less and anything bigger is a little more with increased size.
Could I use this for a water change system?
One of your most useful and most informative videos. Simply explained so even I can build one!
I have followed your diy overflow video and have built the very same design but the problem I have is that when I shut off my return pump and the water level in the tank drops below the top of the drain pipe it wont self start when I switch the pump back on and have to self prime it every time could you please pint me in the right direction on where im going wrong
I made the upgraded version with 1” pvc, but I’m only getting 60gph out of it. What did I do wrong?
So, if I have an outdoor aquarium and it rains, will this overflow pipe stop it from overflowing or does it need to be manually handled everytime?
I might have to try this because I m having trouble with flow , my tank flow is not like most i have seen ,not hard but rough and they coral thrive .what IM i missing ?
Hi, am a little confused, is this imperial or US liquid gallons? How much in Litres… Lets say i have a 5000L/hour return pump….what kind of diameter am i looking at? 2" or 1.5'?
Thanks this is great information and a pretty simple solution. Which kind of PVC glue can be used to join the different pipe sections? I am concerned about pvc glue being toxic to fish
What happens if air get in to the over flow
Hello sir.
I want to buy it could you suggest me the website for this or link for purchase
Why is the outpipe so low? Doesn't it risk of sucking air bubbles inside the system by stopping and resetting? Because the water level in the system sinks down to the level of the output an this is just above the bow inside the tank.
Is there a way to siphon it with out the check valve?
Hi is there any othe way to prime it with out the valve added. Thanks
Hey Joey I got the black pain in a can its kRylon fusion all- in – one paint+primer color is matte black is saying it can be used for plastic will this be safe for my reef fish??? Can you please get back to me asap thanks tom Mack
Hi there, thank you. I want to use an old aquarium in an aquaponics system with a sump. This was the part I was missing in my system. Thanks again.
I've tried this. Seems like a waste of time. Just drill the tank and be done with it.
Tried this out today worked like a charm the tricky part was getting it primed love your stuff man keep up the good work
Whats the size of the tube and how many lph?
King of DIY ….. okay…. your details are weak, terrible explanation. I can understand why you got so many why’s. From watching this I believe you don’t have the slightest idea what you’re talking about.
Where does the outlet water go
And how can it be modified to be used in a sump filter
