Hello all. Need advice. My 637 pump died on my intex 16 ft ultra frame. I want to upgrade to the 2500gph. Read many bad things about hooking up a bigger pump to the 16ft pool. Sucking air and collapsing gasket. What store on amazon do you recommend? I wanna be able to buy the 2500 pump, 1 filter, plunger valves, hoses and everything I need. I'm on the fence about the type B adapters. Read many things about they are junk. Yes, I will even cut my openings bigger for the upgrade. Before I posted this I have read alot. Would appreciate any info. Thx all.
