How many bulkheads?

[KABALA]

Just curious anyones input on how many bulkheads would you use for a 125 with a mag 12 return? 1-2 incher? 2-1 inchers? 2-2 inchers. with max 6' of head not sure how to do all the math to make sure I have enough pump. I dont mind backing down the return flow but just want to have enough pump to not overflow the  sump. Thanks for your help

Mike,

 

I have a MAG 24 running my 125.  I have it teed off to two 1" returns.  I am not sure what you mean by having back the pump down.  If you mean use a valve to reduce thw flow, the answer is no.  The pump is running at full blast.

Eddi,

 

You have 2 1" returns.  What do you have for drains?  What kind of standpipes?

no its full blast but it has around 3.5ft of head so it throttles itself back. i use 2 stand pipes and each pipe go into the sump separatly, as to prevent stuff clogging one and blocking the whole system up. the oveflow holes are high up, so i added strainers and have to tilt the elbow for max flow.
