I've had these Topsflo pumps for about 3 months now and it was time to perform some real testing and give everyone the answers they've been asking.
Keep in mind that there are a lot of other similar DC pumps out there with plastic heads and they are NOT this one. Even the Topsflo brand had another stainless head pump out about a year ago and that was completely redesigned. I can ONLY vouch for the accuracy of the results in the video if it's the current TD5 model.
The real world pumping tests we did in the video resulted in the following data. Note that we cut the 84" head test from the video just to save run time.
40" of head:
Chugger 6 GPM
Topsflow 5 GPM
84" of Head:
Chugger 4.6 GPM
Topsflo: 3.3 GPM
