So far so good. After an hour or so their are no leaks. A few minor problems. Slight flushing effect in the sump and the pumps are a bit louder than I expected. Hopefully the closing up the stand with some foam board will cut down on the noise some. If not I'll just turn the stereo up a few notches. Neighbors be damned, I've got massive flow. :lol:

heh!

Think Sequence pumps.


Sometimes it may be a matter of isolating some harmonic that the plumbing system is setting up, try using flex pipe and a set of rubber foam insulators to try and dampen the footpads and/or varying the length of the plumbing pipe, changing 90 degree turns to sweeping turns, etc.

Sometimes all that is needed is a reduction in back pressure, try running the pump with a large diameter opening for the return to see if it resolves the noise issue.

I'm already using flex pvc. The foam insulator is a good idea, I'll give that a shot next. The flushing issue has been resolved. I just had to increase the length of one pipe. I tried calling PCI to see if there's a break in period, sadly there isn't anyone there on saturday. Without the two CLS pumps running the tank is virtually silent.
