Sand Pool Filter Service

    Reliable, low-maintenance filtration for your swimming pool. We provide professional sand replacement (media change), valve repair, and deep-cleaning services.

    Dependable Filtration Technology

    Sand filters are one of the oldest and most reliable forms of pool filtration. They work by pushing water through a bed of specialized filter sand, which captures debris as small as 20-40 microns. While they are durable, the sand eventually becomes "rounded" and loses its filtering ability, requiring a professional media change every 3-5 years.

    Media Replacement

    We remove old, calcified sand and replace it with high-quality silica sand or glass media to restore optimal filtration.

    Valve Maintenance

    We service and repair multi-port valves to ensure leak-free backwashing and proper water routing.

    When to Change Your Filter Sand

    • Cloudy Water: If your water won't clear even with balanced chemistry, your sand may be too smooth to capture fine particles.
    • High Pressure: If backwashing only lowers pressure for a day or two, your sand may be "channeled" or clogged with minerals.
    • Sand in the Pool: This often indicates a cracked lateral at the bottom of the tank, requiring internal repair.
    • Age: Most residential sand filters perform best when the media is replaced every 3 to 5 years.
