Installing a 16x32 inground liner pool and trying to troubleshoot an issue with the pump. It's a Hayward Northstar 1 hp and there's little bubbles in the clear window that locks above the skimmer but no air bubbles in the return to the pool. The skimmer is working fine and the return flow is strong, should I be worried? Will this hurt something long term? I've checked all the connections and they seem pretty good, I've read on other forum posts that the union fittings on the Northstar can suck air into them but everything looks ok. Scratching my head now!
Thanks in advance for any guidance!!
