Filter Cleaning — Quick FAQs

Straight answers on PSI, flow, cartridge/D.E./sand cleaning, and what to expect on a visit.

• ›What’s the fastest sign I actually need a filter cleaning?

  If your pressure is climbing and your return flow feels weaker, the filter is restricting circulation. We confirm it with a baseline PSI reading and a quick equipment check before we start disassembly.
• ›How often should I clean my pool filter in ?

  It depends on bather load, trees, storms, and your filter size. The best rule is PSI-based: once you’re roughly 8–10 PSI above your clean baseline, it’s time. We establish that baseline after a proper cleaning.
• ›Cartridge vs. D.E. vs. sand — what’s different about the cleaning?

  Cartridge: remove and deep clean pleats (rinse + degrease/soak when needed). D.E.: open the tank, clean grids/manifold, then recharge D.E. to spec. Sand: proper backwash/rinse, inspect valve and sand condition; sand changes are only recommended when the bed is channeling or worn out.
• ›Can a dirty filter cause algae or cloudy water even if I’m adding chlorine?

  Yes. Restricted flow means poor turnover and uneven sanitizer distribution. Cleaning restores circulation so chlorine can work efficiently, and it helps your water clear faster after heavy debris, storms, or high swim weeks.
• ›Do you just “hose it off,” or do a real deep clean?

  We do a real clean. A quick rinse can leave oils and embedded debris in the media. We remove the elements, rinse thoroughly, and degrease/soak when necessary so the PSI drop is real—not temporary.
• ›Will you tell me if my cartridges/grids are worn out instead of wasting a cleaning?

  Yes. We check for torn pleats, collapsed cores, brittle grids, cracked manifolds, and damaged seals. If replacement makes more sense, we’ll show you what we see and give options before any add-ons.
• ›Do I need to be home for the filter cleaning appointment?

  Not necessarily—just ensure equipment access and power. If you won’t be home, a card on file is required. Text the word “link” to 631-928-0225 to receive a secure payment link (no logins or calls needed).
• ›How long does the visit usually take and what do you verify at the end?

  Most cleanings run 45–90 minutes depending on filter type/size and how loaded it is. We finish with a final PSI reading, check for leaks/air issues, and confirm the system is running clean and steady.
