getting tank drilled how to plumb?

[deeboi]

looking for ideas, i'm getting a tank drilled on the top. there are 2 bulkheads on each end with other return/loop holes across the middle.

i'm looking ideas for running the intake bulkhead piping running those to the sump...actually i need ideas how to run those. hard to explain with out pictures...anyone have a link?

i'm posting two designs that i know of. trying to see which one is preffered, and also quieter. i think the first one is similar to a durso? type..

this one is sealed, the piping would go at a 90 degree, and straight to the sump..

Definitely the first way, you need to vent the pipe to keep it reasonably quiet. You can also put a street ell in the tank to make a surface skimmer on one or more of the overflow holes.

thx...i would go also with the first design also. i seen a tank at a lfs that had the same design. but i just for some reason see water pushing out the top of the tube...(1st one)..

for the street L on the overflow tube, wouldn't that change the water level in the main tank? it's just an "elbow" on the inside of the tank right? probably if there was no connection on the overflow bulkhead, i can just hear the water noise now comming out of that hole..

I have 4 x 1" bulkheads in my 135, 2 at each end. I use one as a return and 3 as overflows. I have elbows on two and one has just a trainer. If the pump shuts off the water drains to the level of the lower hole, but I have plenty of room in my sump (it is a 300G Rubbermaid ).

I don't find it too noisy, the venting keeps it from gurgling.

cool. that kind of description was exactly what i was looking for. do you any chance have pictures of the back of this tank?

it kind of raises the water level from what i can see. so all 3 of your intake overflows have to be exactly the same height? the way that's set up looks like the it would make noise out of the front?

then i guess the next question is how do you have the return plumbed? is that it in the picture to the left?

Here is a picture of the back, but it is kind of hard to see what is going on. Also. it is a different surface skimmer setup, my new one is quite a bit better.

The water comes out of the overflow with a street ell (in the previous setup there was a space limitation in back of the tank, otherwise I would have just used a tee) and then into a 1" x 1/2" tee.

There is a 1/2" street ell coming out of the tee pointing straight up. Connected to it is a few inches of 1/2" pipe.

I have a street ell and a regular ell (pointing down) at the top to keep stuff from falling in the vent.

What you should do is put a few inches of pipe in the top of your tee to make sure no water could flow out if your drain somehow backed up. I would top it with two ells as well to keep junk out.

The drains don't all have to be the same height, the two bulkheads in the previous photo are both drains.

The return (not shown) has nothing covering it.

so those are two drains right next to each other it looks like. sort of hard to see but is the one further into a tank a tee? why is there so much extra piping?

 

[deeboi]

....drains to the level of the lower hole, but I have plenty of room in my sump (it is a 300G Rubbermaid ).

I don't find it too noisy, the venting keeps it from gurgling.

^^do you have a pic of your sump or a thread^ sounds killer diy..

I don't want to complicate this thread too much, but, I used the unvented version on my 100 and it is completely silent. I used four 3/4" drains very similar to Dan Feller's and I get no gurgling at all.
I'm not saying Dan is wrong just sharing my experience with my setup.
Although I am currently using a closed loop filter system, The drain was designed as a gravity flow for a sump/refugium.

I'm still playing with the sreet ell's in the tank so they aren't painted yet.
