Skimmer Cover pops off when pool turns off

Postby bradel » Sat 03 Jan, 2009 13:28

Hello! I have a 2-year old inground pool. When the pool turns off, the skimmer cover lid pops up and water pours out the hole. What is causing this problem? It does not happen all the time.

Thanks for your help! :D

Backflow from the pump or filter.

A faulty check valve.
