Thanks Matt for a great presentation! I found it very helpful and it got me thinking about my plumbing...again.
I have two drains in my system. One at each end of an 8' tank. First, the water flows through a toothed overflow (12"x5") then a Durso standpipe (1 1/2" dia). Then through 1 1/2" flexi tubing to my sump.
The difference between these drains is, one sides flexi tubing is about 2' long and the other 5' long.
What is happening is the longer side seems to be doing most of the work, by about 3 to 1. I'm running an Iwaki MD55RLT for my return(i'm guessing with 4' head, around 900 gph ??). The tank has been running like this for about 7 months without a problem, but i'm curious why this is happening.
I'm very interested in your reply.
Thanks again, Patrick
