    Strong skimmer, weak vacuum port

    Recently I notice my vacuum robot doesn't run around the pool anymore. I tried cleaning the robot in and out but still no help. I tried plugging the robot to the skimmer line and it worked perfectly. My vacuum port on side of the pool is just very weak overall. I can feel suction but very very weak.

    When the valve is open all the way for vacuum port only, barely any water flow through the pump.

    What could be problem? Is my vacuum line clogged? I tried drain bladder but no help.

    Thanks

    Welcome to TFP!!!

    Either the vac line is clogged or you have something wrong with the valve settings.

    Did you try running the drain bladder backward from the pump toward the pool?

    Do you use a leaf canister with your suction cleaner? You must to avoid clogging which is what I am guessing the problem is ... assume you do not have the valves messed up.

    No leaf canister, I guess I will try to snake out with a much longer auger. 25ft didn't reach very far for me
