Your pool skimmer cover is used as a safety and maintenance
feature. It is meant to prevent debris, other items, pets and people from
falling into the skimmer well. It also provides a point of access to the
skimmer for your swimming pool. Sometimes your skimmer lid will get cracked or
broken over time and will require replacement. Once your contact your local
pool professional to obtain the correct size for your pool, you will need to
replace it.
