I'm really confused as to what this could be. I'm not sure if the brand new pump is having issues or if there is somehow a clog somewhere in the plumbing. I just got done running new solid 2" pvc pipes for my return and skimmer, and hooked up the pump today. It's a Pentair Intelliflow VS running on 110v. It starts to run, seemingly fine, and I can see water slowly start to fill the basket and then eventually come in a rush, but all of a sudden it will slow way down and the water stops flowing. Then it will start to ramp back up and repeat the process.
I don't have anything in line besides my filter, no heaters or anything like that. Just to eliminate the possibly of it being somewhere in the return, I changed my filter to waste, but no joy. I was very careful not the get any dirt/rocks in the lines when I was running them, although I did notice some small bits in the pump filter basket when I first started it up. I can't imagine it would be some sort of clog in the line but I guess I can't completely rule it out either. If it were though, I don't think I would see the water flowing into the pump at full speed at all.
Anyone have any ideas?
