I have a new Pentair SuperFlo two speed pump and have a couple of questions.
1 - When switching from low speed to high speed do I need to first turn off the pump?
2 - When I'm running my pump on high, the clean DE filter pressure is about 12. On low, its about 4. Does that sound right? I understand it would drop but that seems like a lot. If I backwash after a 25% increase like you say on here I would be backwashing at 5. That seems a bit prone to error and excessive. Input?
3 - Is there an easy way to open the canister lid on this pump? I really racked my knuckle yesterday getting it off. My Hayward was easy compared to this and I'm not a small guy. Do you guys hit it with a mallet or something? It says to release pressure before opening but other than pulling the drain plug how would I do that? Open valve on DE filter?
As always, thanks a ton.....
