i have a pretty straight shot to my sump. actually, after i made and installed a stockman standpipe, the gurgling and slurping noise stopped. however, in my outer outflow box, i am getting waterfall noise as the water goes over the baffle that separates the siphon tube chamber from the drain chamber. i was able to reduce the noise by cranking down on the ball valve of my return line. so therefore, i was curious as to my actual flow. (btw
, i also adjusted the hole size on the top of the stockman).
right now, noise is not the problem. i just want to make sure that i still have enough flow. i know what the flow should be at the calculated head height when the ball valve is fully open.
, that said... has anyone ever used a flow meter to get an accurate reading of the return output? if so, what flow meter did you use and where did you get it?
