Silent and Failsafe Overflow System

[Reefski's]

They all flow into the garage where the sumps are. I think the siphon one could be the one that feeds the overflow to the two glass tanks.

The two in the center of the tank are also 2â€Â and difficult to get to. I don’t know if there is room for any kind of elbows in there, maybe one, or maybe one emergency and one smaller like 1â€Â or 1 1/4 “ Durso

My surges are siphon with a Carlson air break. The water fills the tank higher than the pipe. My experience with that makes me wonder at what height I should put the siphon in the overflow.

This surge will hopefully also be a turf zone one day. I need to get a better material for the turf to grow on than acrylic.

My total overflow from the surges and sump return is about 9,000-10,000 gallons per hour.

The overflow wier teeth ate 3â€Â but you can see in the video the water fills to the top of the tank when both surges fire at once. I could change the flow out of the surges to make them fire more often but less if need be.

So I need the siphons to accommodate the surges and still be silent. Do you think I can accomplish that?

It seems like the one siphon could easily run the 9-10k and maybe need to be throttled back a bit, with maybe 2-3 durso with one emergency overflow.

How would you lay it out?

Hi All,

Finally got my tank drilled and overflow box put on. Tank is a 75 gallon with a 36"L x 5"H x 4"W overflow box centered on the back wall.

Wondering what type of bulkhead I should get. All my plumbing will be 1". Should the bulkhead be slip or thread or combination of both? Do the elbows that will be sitting in the overflow box thread into the bulkhead? Or do they just slip in? I don't think glue would be a good option for the elbow in the box as it would be a major pain if I ever needed to switch it out.

Same for the other side of the bulkhead....slip or thread leading to the T in the standpipe?

Thanks

I have always gone with slip x slip bulkheads. I never glue the inside tank elbow.

 

[Reefer2727]

Thanks Ironwill,

You just slip the elbow in the bulkhead within the overflow box? It will stay put on its own?

Also, when glueing the other side of the bulkhead. Do we typically put a little piece of pipe to mate the bulkhead to the Tee in the standpipe? Or does the Tee get attached to the bulkhead itself?

I will assume the Tees are slip x slip x slip?

As you can tell I am a total rookie.

Thanks for the help.

Reefer2727...you will have a piece of pipe to mate the bulkhead to the Tee...the size of this really depends on how far out you want the overflows to extend (ie...do you have any clearance for the back of your stand?) For example, my stand has about 3" extra behind the back of the tank so I will measure my pipe that joins the bulkhead to the Tee to clear that...and of course I will be looking into the best way to support the overflows to the back of the stand as well.

The elbow on the other side of the bulkhead are a similar setup...small piece of pipe between the bulkhead and elbow...you should be able to slip them on there pretty snug (don't "overdo" it tho) so they will stay in place without having to glue.

Tee's are slip all the way around

 

[jb61264]

Reefski...will be interested in hearing the "pros" answer your questions...but wow...what a setup! that surge setup is really something...never seen anything like that before! beautiful setup all the way around

 

[Reefski's]

thank you!

i love the surge and if i could make it quiet i will be totally in love with it.

i hope the pro responds as i have some time tomorrow to work on it.

Thanks JB

So the elbow will be snug and not glued. Now, the piece of pipe that mates this elbow and the bulkhead together, is this little piece of pipe glued to the bulkhead?

Use a street ell, no need for a piece of pipe.

[Reefer2727]

Thanks Uncleof6.

What about the threaded caps on the top of the standpipes? Any advantage to this versus just using slip caps and glueing?

 

[uncleof6]

the threaded caps can be removed to clean out the drain pipe. Use teflon paste on the threads, not tape. Make that on all threaded connections.

Bean, I'm about to start my setup and was wondering where did you find the sanitary tees? I've checked all the hardware stores and they only carry the black ABS. I was lucky enough to find two at my local aquarium store but I still need one more.

Home Depot, Lowes, Menards, any plumbing supply..............

I've checked all those.. I went to Lowes, Home Depot, ACE Hardware. They only carry the black ABS. No one has them in stock.

 

[teesquare]

EVERY store that sells PVC pipe and fittings sells sanitary Tees

You just need to find the right person in that dept. to assist you.

If you search this thread - you will find that this has been gone over and over. There is even a link to a picture of one.

Wish you luck-

One thing to note is that Sanitary Tees only come in >sizes greater then 1". I may be mistaken, but I think you actually think they make them in the 1.25" and up (working from memory here,) but I'm positive they don't have sub 1" sanitary Tees, adn I don't think they even have 1" sanitary Tees.

 

[teesquare]

That is correct. Sanitary tees are commonly available in 1.25" - 2" at home improvement stores.

They will be in the SDR section of PVC plumbing. You may be able to find other sizes through a specialty house, or www.savkoplastics.com

my HD and Lowes around here only sell the black ones as well. I have spent countless hours in the plumbing section and do not see how they could be there without my knowing it. I am planning to use the black ones - I recall a thread regarding the ABS and that it was ultimately fine for our tanks.

Seeing as this page is 63 pages long (at least..) A question about a 2 vs 3 outlet setup. Apologies as I'm sure its been answered before.

IF one pipe is on a siphon, and it handles all of the flow (below the backup drain). If the siphon tube was clogged (no more siphon/draining on that channel) the second tube kicks in. As long as the second tube can handle all of the flow, why the need for the third tube? Is the third tube a second backup
