I have a dedicated vacuum suction side port that runs my vacuum. After a storm with a lot of pool debris I noticed the vacuum barely moving. I unplugged the hose from the port and turn all the suction to it and I can barely feel anything. Typically it would be hard to pull my fingers out of it. It is on a valve with the pool bottom center drain. I move the port to that drain and the suction works great. So I'm thinking between the side port and the valve there must be debris (leaves, nuts,branches) clogging the line. I tried cycling the valve back and forth to get enough suction to pull the debris though but nothing changes. Does anyone know how I can clear that line?
