Basement Sump Pump Advice

[blstravler]

It seems like a lot of these pumps come with their own controller and in readings reviews many people keep them at a lower setting - I’m assuming the graphs showing loss of pressure is the pump running at 100%. So if flow is 1000 GPH at 10 ft that’s with the pump cranked to 100% - if I go to 75% flow is 750GPH and at 50% my flow is down to 500GPH or is the scale not the same?

I shouldn’t need to have any - could do flex PVC all the way down - should have enough flex to get out of the stand and straight down to the pump.

Ive been running it a year. Still haven't cleaned it. Most want the fan club pumps. I bought two for what they pay for one. I have a back up shelved and waiting.
