    Unhappy Circulation problems

    Hi, I have a real dillema w/vacuum line presure. I have a 20k gal pool; hayword pool vac, and 10, 3' sections of vac hose. When properly working, the line pressure is about 10lbs. Put brand new sand in filter, 250lbs, and backwashed. Still getting less than 5lbs of pressure on line? However, when I left robot hooked up and backwashed, line pressure shot up to 10lbs and robot took off. What gives? Any ideas?

    My skimmer /main drain may b clogged also. My filter is running high @ 52lbs and my vacuum line isn't above 3lbs?
