I am getting very little suction when I hook my Pool Cleaner up to the vacuum line. I checked at the pool pump end and no clogs in the valves or pipes. I hooked the Pool Cleaner up to the skimmer line and it worked fine, excellent suction.
What's the best way to unclog the vacuum line as that's what the problem appears to be. It's about 20 feet from where the line is in the wall to where it comes up out of the ground at the valves next to the pump. There are two 90 degree turns to get the pipe to the valve and then a 90 at the valve based on the pool piping plans (plus I confirmed the pipe locations/layout while they were building the pool...)
Thanks in advance for any help/advice.
