Too much suction !!

you say it won't roll..is this an auto vac? does it have a regulator attached to the hose that you can control the suction with? i've had that problem with both an autovac and manual. especially with the manual as it had no regulator. in my case, i've got a main drain return and skimmer return so i can simply open the main drain a bit to reduce the suction. not as convenient as a regulator on the hose. i have been considering installing a valve that allows some air to get into the vacuum line going to my skimmer (as is the case on the auto vac line) and that would work great.

ps- you said it didn't happen..now it is..i'm guessing that your filter likely needs cleaning. i know with mine that when my filter is dirty, it goes from a standard 10 lb per square inch clean to 15 when dirty, which in turn creates more water pressure in the system overall, leading to stronger suction.
