got a plumbinq question..

[Ageno]

I am currently setting up a 180 DT system with a 75g sump and have two questions for ya'll

1) I already have a Panworld 200 PS 1750GPH that will have 3' of head pressure
And Im thinking of using four 3/4" return lines(already has two). bad idea?

I am thinking of drilling in between the two overflows with a 1" bulkhead near the bottom T-ing off that line into two 3/4 lines that would face the back of the tank, blasting the rock work..

I know.. vortech.. vortech.. Which I will add as well or even the Tunze 6105, not sure yet.

But does this sound like a bad idea...?

2) plumbing diameter.... The drain lines are 1" in the overflow with 3/4" returns to loc line.
I was thinking of using 1-1/4, in and out of the external pump, T'ed, feeding the 4 return lines as stated above. Or should I just keep everything 1" (drains and pump) 3/4" returns (x4). I hope this makes sense.

thank you !

4 return lines is no issue if your return pump can handle the head pressure if you use 4 valves on each return. Either include a check valve or make sure you have a anti-siphon hole near the surface of the water for the returns

Go as big as you can, although you are bottlenecked at the bulkhead for the drain lines, I'd still beef it up to 1.25-1.5 inch PVC on both sides of the bulkhead. Also run as big as you can for the returns, smaller lines only increases pressure.

thank you !

Good luck!

If I had a big enough tank with multiple return I'd put in a second pump. I always worry about my return failing. I like the idea of having 2 so if one fails I'm not crashing
