So I have struggling with a huge air leak in my suction system. Today after fighting wth the pump and cavitation in the pump I was determined to find it. The pool company wanted to pressure test and sonar etc for $$$$. I fabricated a hose connection to my skimmer inlet, closed the ball valve and turnerd on the hose. Within about 30 seconds I heard the tell tale signs of water blowing underground. Seeems at some point in the history of the pool there must have been a leak under the deck and somebody cut the original suction line (blue pipe in picture) and ran about three feet of flex pvc in between. Well both joints of the PVC to this blue stuff were blowing water and clearly letting in lots of air. The pool guys saw some of this stuff in the yard as the pipe is shallow and they were confused as to what it is. It is not flex PVC, but does bend since they curved it around my concrete pool deck.
So I want to try to repair this break in the line. I have enough flex PVC laying around to reconnect the break. I know flex PVC can use the same cements as normal PVC, but what about this Blue stuff? The blue goo in the picture is kind of flakey looking like an epoxy or something and this last polar vortex the midewest had must have destroyed it.
Appreciate the help.
