Pool Filter Repair & Cleaning in Lexington, SC

Your pool’s filter is responsible for removing debris, contaminants, and microscopic particles from the water. When the filter isn’t working correctly, your pool water suffers — turning cloudy, developing algae more easily, and putting extra strain on your pump. Sands Pool Care provides professional filter repair, cleaning, and media replacement for all filter types in the Lexington, SC area.

Filter Types We Service

Cartridge Filters

Cartridge filters are popular for their ease of maintenance and fine filtration. Over time, cartridge elements degrade, develop tears, or become too clogged to clean effectively. We provide deep cleaning, cartridge replacement, and housing repairs.

Sand Filters

Sand filters are reliable and low-maintenance, but the sand media needs replacement every 5–7 years as it wears smooth and loses filtering effectiveness. We handle full sand changes, lateral repairs, multiport valve rebuilds, and internal component replacement.

DE (Diatomaceous Earth) Filters

DE filters provide the finest filtration available but require more maintenance. We service DE grids, manifolds, and internal assemblies, and we handle DE recharging after cleaning.

Signs Your Filter Needs Attention

• Filter pressure gauge reading higher than normal (8–10+ psi above clean baseline)
• Cloudy or hazy pool water despite proper chemical levels
• Water pressure drops significantly at return jets
• Short filter cycles — needing to clean or backwash much more frequently
• DE powder or sand returning to the pool through jets
• Visible damage to cartridge elements, grids, or housing

Filter Deep Cleaning

Regular backwashing or hosing off cartridges removes surface debris, but over time, oils, minerals, and fine particles embed deep in the filter media. Our professional deep cleaning uses specialized chemical soaks and thorough rinsing to restore filter performance. For most pools, we recommend a deep clean at least twice per year.

When to Replace Filter Media

Cartridge elements should be replaced every 1–3 years depending on usage. Sand media lasts 5–7 years. DE grids typically last 7–10 years with proper care. If your filter isn’t performing despite cleaning, it’s likely time for a media replacement. We’ll inspect your filter and let you know.
