Just a quick (hopefully) question.
We've recently gotten a 2-speed pump (1.5/.75hp) and I've been running it on low most of the time and then boosting it when I need my polaris 360 to do some work for me for a couple of hours a day. What's weird is that I've been noticing the pressure jumping up faster than just running it on high, like my old pump.
Yes, I understand the extra pressure from going to the 1.5hp is going to boost the pressure inside the DE filter, what I'm wondering is it hurting the DE filter by running it on low so much, maybe not getting enough pressure on the grids, the DE dropping off the grids and creating extra pressure when I switch to high? Should I just run it on high 8/10 hours a day vs. 18/22 on low and 2/4 hours on high?
Hope this makes sense.
Thanks ahead of time for anyone's assistance.
