HOW IT WORKS: PVC over flow

[MEGAONE302]

Great work sir, thank you...

[rjbrocklesby]

there is lots of air coming out of the cheak v it is like a small whirlpool going into the inlet

[0987pops]

Getting alot of air going into the overflow pipe why is this



[uarujoey]

@0987pops what do you mean by this? does it keep loosing siphon?

[Wolfsicklid]

Hey superstar I built one for my 125 and it has a two way valve I also put it coming from underneath the tank with glass around it on the corner it's custom and looks great alot of work I am still building the tank but I will have videos up soon it has a custom all glass wet dry filtration to it's for my wolf cichlid

[TheOverlordglee]

can the loop on the out side of the tank be lower then the loop in the tank as long as the 3 way ( T ) is still higher then both loops?

[uarujoey]

@TheOverlordglee yes, that should work as well. 

[CHIEFKCRUE]

great video I built one also. one problem one time it stopped taking in water and I had to once again bleed air from the oneway valve any idea how to correct? I used 1 1/4 pvc worked fine last two weeks but had to restrat siphon last night as it started to overflow

[superstarboi]

for a 125 gallon, what diameter pvc would you recommend for the best most efficiente water flow and how many gallons should the pump be able to pump back into the tank? i have been watching your videos for a long time and i think i am finally going to build one of these for my 125 gallon.

[selectorenuff]

this is great work keep us informed

[CardinalFilefish]

Can you have the pvc thats draining water into the sump bigger than the pvc going back to the tank if you have a strong enough return pump?

[obleck2018]

Can you show a video wit the over flow in action.

[uarujoey]

@obleck2018 I have a complete video on how to put it together, how to start it, and i show it running. Check my other videos.

[2hype00]

Can you build the overflow without the check valve and still get it to function?

[metallicafan117]

I can't seem to find the type of check valve you describe. Can you give me a link to a site where I can buy one?

[Starrwulf7]

@metallicafan117 you can use the one that came with your air pump or check ebay.

[fuelban]

well explained video, thanks.

Thom in Scotland.

[uarujoey]

@fuelban Thank you Thom.

[smokinjojo74]

for the video and any advice

[smokinjojo74]

thank you

[smokinjojo74]

very nice job on the video, its a great solution to buying one of overflow boxes. i was thinking of building one for my 56 gal fowlr, but i have a couple questions about the return pump for it, lets say i use a 660 gph powerhead for the return, two of the 1 in pipes would be able to keep up with that right? the idea im getting is depending on the amount of water flowing back up into the tank from the sump will dictate the gph of the overflows as long as it doesnt exceed their flow rate.

[uarujoey]

@smokinjojo74 Your right. And 2 1" bulkheads is fine.

[smokinjojo74]

@uarujoey alright, thank you. take care

[slimo41]

that's a terrible system! buy a real overflow.

[uarujoey]

@slimo41 I have bought over flows, i have drill and plumbed my own aquariums, and i have built several types of overflows. they all work on the same principle, and on the same idea. This overflow works just like any other style.

[carislow]

THANKS, THE VIDS HELPED ALOT. I'm building a tank like the plywood one that u built. i was concerned with the cost involved esp for the filter setup but u made everything cheap and easy to do, like the filter cost. i am prob going to put the overflow lines in the tank but in this vid u say to use 2 overflows. would it cut the cost in half or so if u put a t at the inlet with 2 90s and a screen to prevent things from gettin sucked up? and do you think that would work on both overflow methods?

[uarujoey]

@carislow A screen on the overflows is a good idea, yes. It would still work with a screen. Just keep an eye on it to make sure it doesnt clog.

[videoramon]

I had a quick question joey, i just do not understand the purpose of the check valve, why can you not just prime out of the air intake pipe? your thoughts on that would be awesome thanks

[uarujoey]

@videoramon The check valve is there so you can remove trapped air from the overflow when air gets in it. It is also used to actually prime it to get it going.

[videoramon]

@uarujoey, thanks for your reply, i did not realize that traped air can get into the top of the overflow where the check valve is. Is that a flaw to this type of setup? How often can you loose your flow because of trapped air? Im guessing it would be depend on your individual setup. But im just wondering if it is something i would have to constantly be worring about? last question sorry but does the trapped air come from the water intake, or from the extented air pipe outside the tank?

[uarujoey]

@videoramon Trapped air is not a flaw to this overflow. It is a flaw to any overflow. Air has the potential to enter any overflow. Its not something you need to worry about.

[KALZONE850]

how loud is it using 1",2", or 3" pipe?

[uarujoey]

@KALZONE850 they all pretty much sound the same. All depends on the size you use, the flow you put threw it, and how well you use the cap to dampen the sound. I can generally get them to be completely silent.

[KALZONE850]

You da bomb bro

[nickjm37fordel1]

I think your videos are the best, very good quality.

Can you tell me why the overflow has to go to the

bottom of the tank ? I saw one made that only went about

half way down, the exit pipe was higher up the tank though.

Is it better to go all the way down to the tank bottom ?

Thanks, Nick

[uarujoey]

@nickjm37fordel1 You can have them to only be the half height of the tank, they still work like that. You can modify lengths quite a bit with these. I simply always recommend what i personally use.

[AweSomo84]

@uarujoey i did have way pipes and now i put a bigger pump on my 32 mm pipes and a 1260 eheim pump thats 2400liters a hour and it makes a really bad noise like flushing a toilet , if i make the pipes till the bottum will this solve my problem or a noise cap or somethingf?

ty,

Erik

[uarujoey]

@nickjm37fordel1 The cap on the top pipe is for noise. Start with a small hole drilled into the cap. Slowly increase the hole size until noise is minimal.

[TURBOJEFFREY]

I wonder whats the cap for on the top of the outside part of the system ?

Did u glu the cap on the tube or is it used to minimise the noise of the overflowing water ?

Thanks

[uarujoey]

@TURBOJEFFREY That is for noise. There has to be a hole drilled into the cap as well, so the overflow does not become a siphon.

[TURBOJEFFREY]

@uarujoey so theres 2 holes then? 1 in the side of the cap and in the side of the tube

[TheSharkchum]

@uarujoey wat size should the hole on the cap be? thanks

[uarujoey]

@TURBOJEFFREY no, just a hole in the top cap. Thats the only cap on this overflow.

[uarujoey]

@TURBOJEFFREY start small and work your way bigger until the noise is minimal. Have a few extra caps to run tests with. There is no set size really, as all flows will never be the same. Too many variables.

[subtankcar1]

yea pvc is 1:95$ for 10 foot and im in kansas city mo

[sonofevil77]

I built one of these a few years ago and it worked great!

[thedylanwoody]

hi so what happens when ur on holiday and you get a power outage how does it auto matickly turn on

[uarujoey]

@thedylanwoody Yup, it would turn back on by itself. It starts back up because it is already primed. When water gets pumped back up to the main tank, water simply starts to overflow out of it again, like illustrated in the video.

[VegasSurfer]

So i am getting a 158GPH pump, what size PVC would you recommend? Also, would the height the pump pushes water upward effect the GPH?

[uarujoey]

@VegasSurfer For 158gph, a 3/4" overflow will be fine. Yes, the higher the pump has to pump the water, the less the flow will be.

[uarujoey]

@skysdad1999 You should be getting double that. HArd to say what the problem is though without seeing it. You should have 2 overflows either way though.

[playtime1104]

how reliable is this overflow i keep tropheous and they are pretty touchy dont want to mess this up but would like to have a sump without drilling my tank thanks by the way love the acrilic build will be building my own soon too i am also from canada toronto scarborough

[uarujoey]

@playtime1104 This is just as reliable as a store bought HOB overflow. Reason being, they work on the same principle. They are safe, reliable and very cost effective. People have been using these exclusively for years now.

Glad your enjoying the acrylic tank build. Last video is up now. Cheers to a fellow Canadian!

[flowboard04]

Wow I love a lot of your videos. I couldn't find a video of how you made your 284 gallon tank! That would be awesome. I think your tank is easily the most professional looking.

[uarujoey]

@flowboard04 Thanks for watching. I dont have a video on how i made my 284gallon tank unfortunatly. BUT, i do have a new tank being built right now! I making a complete tutorial on how to build an acrylic tank, start to finish.

[baseballman1321]

when you have two over flows can you plumb them together with a T piece

[uarujoey]

@baseballman1321 Absolutely! great question as well. You can do it, but the "T" must be able to handle the flow, so make sure you use a larger diameter pipe if your using both overflows to handle all of the flow. If your using two, for safety reasons, then the same size pipe is fine.

[baseballman1321]

@uarujoey ok thanks, should i use flex tubing or pvc from the T connecter to the sump

[uarujoey]

@baseballman1321 Flex is generally better due to the ease of moving it around when you need to. It is also generally quieter then a pvc drain. If you allow a small loop in the hose, it will allow for water to build up and fill the hose. Then you wont get the noise associated with falling water.

[drumgawd11]

Thank you so much for this upload! I'm learning something new from every single one of your videos.

[uarujoey]

@drumgawd11 Im glad you enjoyed this video and are enjoying/learning from my others. Please feel free to inbox me, or comment on my channel about something you'd like to see in a video, or any ideas for one! Im always up for suggestions!
