Pump Sucking Air; Won't Prime - Needed to be primed

[fog80]

I had air getting in where the pvc goes into the hayward superpump, some caulking fixed that right up. Listen real close for any "hissing" that was what gave it away for me.

Glad it was something simple. I'm surprised that you could hear any hissing with the pump running but I guess you have good selective ears, like a dogs sense of smell.

Thank you for all of your advice. After scouring the Internet for hours, I finally just went out there and did some investigative work. After taking the basket from the pump and watching the water flow, it was obvious I was sucking air because of the lack of water in the actual pump basket.( I knew it wasn't o- ring or lid problems as the pump is only a few weeks old) So I narrowed it down to either my line was blocked with debris or I had a leak. No leak could be found so I literally took my plunger to my skimmer and sure enough I had acorns trapped in my line. I few minutes of plunging and rinsing my filter out fixed it. It's working beautifully now.

That's great. Sometime it's just common sence.
