Why is skimmer flushing?

Skimmer flushing occurs when the water level in the skimmer is too high, causing water to overflow and spill out of the skimmer. This can be caused by a number of factors, including:

1) High water level in the pool: If the water level in the pool is too high, it can cause water to back up into the skimmer and overflow.

2) Clogged skimmer basket: A clogged skimmer basket can prevent water from flowing freely through the skimmer and can cause it to overflow.

3) Blocked skimmer line: If the skimmer line is blocked, water cannot flow freely from the skimmer, causing it to overflow.

4) Faulty skimmer valve: A faulty skimmer valve can prevent water from flowing freely through the skimmer and can cause it to overflow.

To fix skimmer flushing, you will need to address the underlying cause. This may involve lowering the water level in the pool, cleaning the skimmer basket, clearing the skimmer line, or replacing the skimmer valve. Once you have addressed the cause, the skimmer should stop flushing.
