is pump adequate?

[100watt]

I'm about to pull the trigger on a diy 18x36 vinyl liner with a cozy cove. The cove has 6 jets, the pool will have two returns, main drain and an aqua genie skimmer. After a little research I'm thinking Hayward Tristar 1.5hp two speed pump. It's plumbed for 2". I'm being told 1.5hp is fine but the 2" is needed to supply the volume consumed by the added jets. I'll pipe the cozy cove with it's own ball valve so we can shut them off when not needed. Any opinions? Thanks

My opinion?
Try to avoid ball valves, especially cheap ones. They often degrade and break within a few years, usually requiring re-plumbing, repairs, adjustments, and often digging too. Please use quality valves, for your own sake.

I'm a plumbing contractor so I know all about cheap ball valves. You get what you pay for. Thanks for the info.

One other question - Schedule 40 rigid pvc vs. the flex? I've been told grubs eat the flex pipe. Any truth to that?
