Durso Pipe - what size pipe?
Getting ready to plumb in the over flow (single) of my 150g - going to use a durso set up - can't decide on what size pipe to use :? 1.5" or 2 " ? Any suggestions ? Same goes for the line down to the sump.

How much flow are you planning on putting through?
With 1.5" you can handle alot of flow and 2".... :shock: Well you would need a huge pump. Do you allready have the bulkheads in place or is this part of your deciding factor as well?

well - I am using a 1 1/2 standpipe and 1 1/4 the rest of the way...
and it moves a rediculous ammount of water. I have to throttle it way back...even with an ampmaster 3000 as my return. |

I might be wrong on this, but, if you're going Durso/Stockman (Stoffman? I never remember the names... ops: ) don't you want the standpipe to be larger than your bulkhead (just using a bushing at the join)? So if you're bulkhead is 1.5" I think you want a 2" standpipe despite that you will likely be going with a smaller diameter pipe down to your sump below the bulkhead.
2" is huge though. I can only imagine what that monster would look like (make sure you have enough clearance in your overflow if that's the size you end up using!)

if I remember what Rich Durso has said perviously, above 1" you don't need to have the restriction/reduction in size for it to operate properly.

I was going to try a simular setup as Jonathan using a LG pump (1250 gph) - if I read right, you need to have a reduction in size at the bulk head and then back in size for the rest of the way for it to function properly.

If you are using a 1.5" bulkhead you don't need to go up to or reduce in size at all. As long as there is a bend in the line heading to your sump that will create the backpressure necessary to keep the durso quiet. I had a 1 1/4 reducer in my durso from a 1.5 bulkhead and took it out to see if it operated differently when I was testing my ampmaster3K. No change.
If you are running a smaller bulkhead the reduction is necssary. All you will do by adding in the reduction after the bulkhead is reduce the max flow of your durso. In this case.

I don't know what you mean but sure
You can pop by some time if you want and give it a closer look.
