Short Filter Cycles
Fix filters that need frequent cleaning
Filter Overload Symptoms
📈 Pressure Signs
- • Pressure rises within days
- • Needs cleaning weekly
- • Flow reduces quickly
- • Pump strains constantly
🔍 Common Causes
- • Undersized filter
- • Heavy bather load
- • Excessive debris
- • Water chemistry issues
Quick Answer
Filters requiring frequent cleaning indicate excessive debris load, undersized equipment, or water chemistry problems. First, ensure the filter is properly sized - it should handle your pool volume with normal cleaning every 4-6 weeks. Heavy bather loads introduce oils that clog filters rapidly. Use enzyme products weekly to break down oils. Check for high phosphates or calcium that create deposits. Consider pre-filters or skimmer socks to catch debris before the main filter. If problems persist, the filter may be undersized for your pool's demands.
Why Filters Clog Quickly
Debris Overload
- • Environmental: Leaves, pollen, dust, rain
- • Bather Load: Oils, lotions, hair products
- • Organic Growth: Algae, biofilm formation
- • Chemical Precipitates: Calcium, metals
- • Dead Algae: After shocking or treatment
System Problems
- • Undersized Filter: Can't handle pool demand
- • Poor Circulation: Debris accumulates
- • Chemistry Imbalance: Creates deposits
- • Damaged Media: Clogs more easily
- • Phosphate Buildup: Feeds organic growth
Key Insight:
A properly sized filter should run 4-6 weeks between cleanings. If cleaning more frequently, address the root cause rather than just cleaning more often.
Diagnosing Rapid Clogging
Step-by-Step Diagnosis
Check Pressure Rise Rate
Note how quickly pressure rises from clean starting pressure.
⚠️ Warning: Clean filter when pressure rises 8-10 PSI above starting
Assess Debris Load
Evaluate amount of leaves, pollen, and other debris entering pool.
Test Water Chemistry
Check for high calcium, phosphates, or algae growth.
⚠️ Warning: Poor chemistry accelerates filter clogging
Verify Filter Size
Calculate if filter is properly sized for pool volume and usage.
Inspect Filter Media
Check condition of sand, cartridge, or DE grids for damage.
Check for Oil/Lotion Buildup
Heavy bather loads introduce oils that clog filters quickly.
⚠️ Warning: Enzyme cleaners may be needed for oil removal
Proper Filter Sizing
Filter Size Requirements
Pool Size | Min Filter Size | Heavy Use Size | Flow Rate |
---|---|---|---|
10,000 gal | 100 sq ft | 150 sq ft | 42 GPM |
15,000 gal | 150 sq ft | 225 sq ft | 63 GPM |
20,000 gal | 200 sq ft | 300 sq ft | 83 GPM |
30,000 gal | 300 sq ft | 450 sq ft | 125 GPM |
Sizing Formula:
Pool Volume ÷ Turnover Rate ÷ 60 = Flow Rate
Flow Rate × 1.5 = Filter sq ft needed
Heavy Use Factors:
- • Many trees nearby: +50%
- • High bather load: +50%
- • Pets swimming: +25%
