Replaced old, old, Polaris with Hayward Navigator, works great.

But...when pump first comes on, it takes about 10 minutes for pump to prime, and Navigator to start working.
But return/supply jets continue to squirt air/bubbles for another 10 minutes, then everyting is fine.
Pool guy says all's fine, (he has same Hayward Navigator), I think I have a slow/small leak.
He says his Navigator starts working within a minute or two.

I'm new to the whole pool thingy, have a pool guy/neighbor helping me out now, for awhile, untill I learn how to do it myself.

Thanks, Wayne
