Well Last night around 9pm I turned on both pumps to see how the flow would work. The lower pump overfilled the tank some while I was trying to figure out why the water wasn't draining into the sump, no problems lots of towels & one mad wife later I got it flowing & rather nicely. I need to work on the drain some more adjust the plumbing & work on the air intake so I can quieten it down. The first initial test went well with the exception of the water LOL, I hope by the weekend to have it running quite, then I'll let it run a few days to make sure it is water tight. I'm very pleased with the performance of the two sequence pumps, extremely quite at least as quite if not more than most submersibles. The CL with the 1/2" Loc-lines & Y's on top really work well, I have great flow throughout the entire tank If I'm lucky I might get the MBV on a timer this weekend also then it will really be kicking.
