70466 Weir Blade Assembly
70466 Weir Blade Assembly

The skimmer weir is located at the entrance to the filter compartment and is designed to allow water to enter the filter area. Additionally, the weir is designed to remove or skim any floating debris from the surface of the water.

When the filter area requires more water (jet pump activation), the weir will move down to allow more water to enter. Conversely, when the filter area requires less water (jet pump is deactivated), the weir will move up to decrease the amount of water entering the filter area.

The skimmer weir consists of a blade assembly, weir frame, pivot button, pivot brace and key.

  • If a weir blade becomes stuck in the up position, the jet pump can surge due to lack of water.
  • If a weir blade becomes stuck in the down position, the skimming action used to remove debris will be eliminated.
  1. With the complete weir assembly removed from the spa, locate the four weir bullets holding the weir blade into the weir frame.
  2. Compress the two bullets on one side of the blade, and remove the blade from the frame.


  1. Remove the filter lid.
  2. Remove the filters and standpipes.
    Caution: Never operate the spa with the standpipes removed.
  3. Locate the weir key under the weir blade.
  4. Turn the key one quarter turn to the right.
  5. Carefully lift the entire weir assembly from the filter compartment.


  1. Reinsert the weir blade into the weir frame. Ensure that all four bullets are in position.
  2. Slide the complete weir assembly into the filter compartment.
  3. Place the each of the two locating pins (top of weir frame) into the center hole of their respective pivot buttons. Do not place the locating pin in any other slot.
  4. After positioning the locating pins, use the weir key to secure the assembly.
