Problems & symptoms
Common problems we fix
Commercial pools work their filters hard, especially with heavy bather loads. When a filter is dirty, damaged, or the wrong media is in place, water clarity drops and the rest of the system has to work harder. We service all three common filter types and fix pressure problems at the source.
Cloudy or dull water
Filters that are dirty, channeling, or letting debris pass through.
High filter pressure
Dirty media, clogged cartridges or grids, or a return-side restriction.
Low filter pressure
Suction-side blockages, air leaks, or pump problems upstream.
DE or sand returning to the pool
Torn grids, broken laterals, or failed internal parts.
Leaks at the tank or valve
Worn O-rings, clamp bands, multiport valves, or cracked housings.
Short time between cleanings
Worn-out media or cartridges, or water chemistry issues.

Compliance & uptime
Why it matters for commercial pools
Filtration and circulation together keep water clear and help sanitizer work. A filter that isn’t doing its job can lead to cloudy water, which is a common reason commercial pools are closed. Regular filter service helps keep the pool open and reduces strain on pumps and heaters.
We’re open 7 days, 6:30 AM – 9:00 PM, with 24/7 emergency service. Pair repairs with onsite computerized water testing or a routine maintenance plan to help keep problems from coming back.
