Hello all, I have been having issues when vacuuming my pool. When I vacuum, the insects and other small debris come back out of my return jet. I also hear a gurgling sound from my multi-port valve constantly. I took my multi-port valve apart and found the spider seal to be damaged so I replaced it. I re-installed the valve and I am having the same issues. I took the multi-port valve apart again and found what I believe are hairline cracks in the housing. i have attached pics. This is a Waterway valve. Has anyone ever seen this? Thanks.
