If your pool skipper is clanking at night when you are trying to sleep. Here is a quick way to solve it. 

When your pump is off and not running your skimmer door goes up to stop debris from exiting the skimmer back into the pool. On windy days the door tends to hit up against the plastic base. Normally not a big deal unless the skimmer is by your bedroom window and you are trying to sleep.  

A quick and easy way to solve this issue. Is to take a piece of an old noodle and cut off about 4 inches long. Also cut a slit into the side and install onto the door. This will still allow the water to flow and raise the door as normal when the pump is off.
