Ok - So I mucking around with it this morning, and it starts to suck in air on the pool intake side too. I decided it could be the jandy valve leaking. Turned the hose on and ran it over the valve - and the problem started going away. While I had the thing open, I decided to stick the drain king into the spa intake side. I've never used one of these before. Anyway, I noticed a "hissing" sound around the area where the intake pvc pipe joint is. Some water also coming up into the spa. No sign of a clog. Re-assembled the Jandy and ran the pool. 100% water coming into the strainer basket. Like new! Turned it to spa - not bad - not great. Some air is definitely coming in. I am pretty confident that it is the joint in the pvc on the intake side. The way this thing is plumbed, it will be a big time pain in the Rear to cut and replace. Any suggestions on "sealing" it for the time-being?
