I have searched the internet for hours and could not find any info.
I bought a house with a pool and tried to open it myself. All is well except I can't get the water returning from the pump to the pool. There was a round clear plastic plug on the deep end, I removed it and broke it during removal (screw in, has 2 dimples for tools which I noticed AFTER I broke it). Now there is some sort of glass fiber rope sticking out of a little screw-on nozzle. I am afraid to pull the rope out as it does not want to come out easily. The pool outlet looks like the one on the top left:
And there is a loose nozzle on the end of a glass fiber rope going into it. And no
water coming out of it
Should I yank this rope thing out? what is it?
