Any recommendations on plumbing (pics)

[BCT182]

I am planning a large tank that will be kept in my garage. I have to request where my holes and overflows are placed.

I am going to use 2" bulkheads.

I am going to use two seaquence power series 7400gph external pumps. One for a return and one for a closed loop.

Attached is a blue print of the tank, if anyone wants to make some suggestions or even copy the jpg. and draw some ideas into the plans, it would be greatly appreciated.

Try Oatey shower drains.... they make great bulkheads, and are sometimes even available in 3".... That's what I have used on 2 tanks now. D

 

[BCT182]

okay cool. How about location of the bulkheads? and overflows?

 

[BCT182]

should I do one overflow all the way down one side, or one in a corner, or one in each corner?

Your a mad man!!!!

Also,
Tank Volume = 1028.6 Gallons
You can say it. A "large tank" is a little vague.

Just remember that according to Loc-line 3/4" can only handle around 1,140 gph max.

 

[BCT182]

yeah, but probably no loc-line on this tank. Just bulkheads...

Any other recommendations?

I would do a coast-to-coast overflow with at least two drain bulkheads.

Excess capacity and redundancy are two very important words ...

 

[BCT182]

I was considering a coast to coast on one of the 5ft ends with five 2" bulkheads for drains.

 

[dnjan]

Not sure I would put that many holes in a row. They would be 10" apart, and then considering the hole diameter itself you would have less than 7" of solid glass between the holes.

 

[BCT182]

is oyur fear it will weaken the glass at anything less than 10" of spacing?

 

[BCT182]

Heres a rough idea of what I am thinkin...

 

[steven11]

I got a recommendation for you!

 

[BCT182]

please dont derail my thread steven. im trying to order this tank friday

 

[dnjan]

Yes, though I don't have any calculations to back that up. I suppose if they are willing to drill the holes that large and that close, and warrentee the tank, no problem.

Were I drilling it myself, I would not be 100% confident.

 

[BCT182]

how about my diagram on post #12. Think thats okay?

 

[BCT182]

Should I have more than one pulling bulkhead for the CL? Im trying to kick 4700gph through the CL

 

[dnjan]

I would. Lower flow velocity at the "pulling" bulkhead means less stuff being sucked up against your strainer (like that piece of nori that comes loose from the clip ...). Multiple inlet bulkheads woud reduce the inlet velocity.

 

[BCT182]

Here's the final blueprint to be submitted tomorrow. Any last minute recommendations?

You can drill into acrylic tons and tons of time and it doesn't weaken it. Glass however is a different story. Also with how thick this acrylic is, it can withstand lots of holes without problems. I have a tank with (8) 1.5 in holes drilled within a 18"x18" square area in .25" thickness and thats totally fine on one of my tanks
