How to Troubleshoot Inground Swimming Pools

Check the skimmer basket and valve openings for a large amount of debris, such as leaves, if the filtration system does not seem to be working properly.

Clean the filter. Each type of filter has slightly different cleaning instructions, but setting the filter to the "backwash" setting will generally be required when cleaning. Consult the owner's manual. Cleaning the filter can help alleviate issues with the pool water, such as cloudiness or debris.

Look carefully at the connections for the filter, pump and hoses. If you see any gaps in the connections or puddles of water, then you likely have a leak in the equipment.

Add 2 lbs. of shock to the pool for each 10,000 gallons of water inside. This can help fix problems with contaminated, cloudy or discolored water.

Clean the bottom of the inground swimming pool with a pool vacuum cleaner. Connect it to an extension pole and move it across the bottom while standing on the deck. Once the pool is vacuumed, cloudy water and debris may be gone.
