That is exactly why I wanted to use these pumps, anything else would send vibration noise through out my house.

Let's say with no piping the DC10000 delivers 10000 lph @ 30PSI right at the discharge of the pump (I have no idea what pressure it delivers but for the argument let's call it that) If your SCWD is 12" away from your pump, good chances are your getting close to the same volume and pressure from your pump and the restriction starts at the SCWD.
But now, let's add 15' of 1" hose. The pump now has to overcome the friction loss of the 1" pipe before the SCWD. So now the SCWD probably only sees 6500 lph. If you can lower the friction loss the water encounters on the way (make it easier for it to get there) to the SCWD, the pump will perform much better.
I tried using some of my firefighting pump formula's but the pressures are too small for them to work, but the principles are the same. Larger hose for longer lengths to get the same pressures and volumes.
Good point I will try that out, get some fittings for 1 1/2" figure out my return hose line length and retest.
