well i could not get the flex tube into the U tubes to prime them without removing the inner box. The box is attached with a plastic nut and screw. so the U tubes are pulling water straight from the tank, which means its pulling at full capcity. maybe i need more U tubes or if i add a SCWD to the output hose in the main tank from my sump pump it may slow the pump down a bit.
, the water rushing down into the sump make quite a bit of water splash and noise. no noise from the tubes but after the first section of my sump, it flows over to my main return section and its there where a lot of splash noise is. any thoughts on how to silence this?
