In planning stages of 180g build, have some plumbing questions

[John08007]

I have a 180g undrilled tank that I plan on using 2x ghost type overflows, these have 3 pipes on each. Can't imagine having 6 pipes entering my sump, anyone have pics of their plumbing in a situation like this. I was thinking I could combine the similar pipes on each overflow, full siphon for example with the other full siphon.i would think then o could have 1 valve on it for adjustment.

Do you need both overflows? Good luck with the build!

Good point, will need to look at the overflow gph ratings and see if one would work. I was just thinking that most larger tanks I've seen commercially made had an overflow ar each end.

I did find info on 2 overflows, seems like you can combine the siphon if you connect the 2 overflows with a pipe Otto stabilize the water level in the 2

Here is how I did that. Siphon 1 and 2 are connected to a single pipe, which runs at full siphon, then throttled with a gate valve. BEAN style with two overflows.

How large is your tank?

1000 gallons. 1.5 inch PVC - one pipe on full suction to the basement is plenty to handle the flow - about 6000 gph.
