Filter Cleaning — Quick FAQs

Aligned with your system checklist (cartridge, D.E. grids, and sand), from PSI readings to safe media cleaning.

• ›How do I know it’s the filter causing weak flow (not the pump)?

  PSI tells the story. If pressure is climbing while returns feel weaker, the filter is restricting flow. If pressure is low and flow is weak, we look at pump basket, impeller, air leaks, or valve positions. We start with baseline PSI and symptoms before we touch anything.
• ›What’s a “normal” clean PSI baseline for my pool in ?

  There’s no single number—systems vary by pump size, plumbing, and filter type. The key is establishing your clean baseline after a proper cleaning. Once we have it, you clean again when you’re roughly 8–10 PSI above baseline (or sooner if flow drops).
• ›Do you remove and soak cartridges, or just rinse them?

  We do it correctly: full removal, thorough rinse, and degrease/soak when oils and sunscreen are present. A quick spray-down alone often leaves the pleats loaded and PSI stays high. We aim for real PSI improvement, not cosmetic cleaning.
• ›Can a dirty filter make my pool turn cloudy or struggle to hold chlorine?

  Yes. Restricted circulation reduces turnover, so debris stays suspended and sanitizer can’t distribute evenly. Cleaning restores flow so chlorine can actually do its job—especially after heavy swim weeks, storms, or debris surges.
• ›Will you tell me if my grids/cartridges are worn out instead of forcing a cleaning?

  Yes. We check for torn pleats, collapsed cores, brittle grids, manifold cracks, and blown seals. If elements are failing, we’ll show you what we see and give replacement options before any add-ons.
• ›Do you handle D.E. recharge and O-ring service during the visit?

  Yes. After cleaning, we recharge D.E. to manufacturer spec (for D.E. filters) and service lid/tank seals with cleaning + lubrication to prevent leaks and air issues. We finish with a final PSI and leak check.
• ›Do I need to be home and how do I handle payment?

  Being home isn’t required—just ensure access to equipment and power. If you’re not home, a card on file is required. Text the word “link” to 631-928-0225 to securely upload your card (no logins or calls).
• ›How long does a typical filter cleaning take?

  Most visits run 45–90 minutes depending on filter type/size, debris/oil load, and access. Larger D.E. tanks or heavily clogged cartridges can take longer because we clean thoroughly and verify final PSI.
