📐 Pool Sizing Guide

Sizing Principle:

The filter flow rate should turn over your entire pool volume within 6-8 hours for optimal water quality. A faster turnover provides better filtration but requires a larger pump.

Formula:

Required Flow Rate (m³/h) = Pool Volume (m³) ÷ Turnover Time (hours)

Pool Size Compatibility:

Pool Type	Volume Range	Suitability
🏠 Medium above-ground	30,000-50,000 L	✅ Excellent – ideal primary filter
🏠 Large above-ground	50,000-70,000 L	✅ Very Good – comfortable capacity
🏊 Small in-ground	40,000-60,000 L	✅ Excellent – perfect match
🏊 Medium in-ground	60,000-85,000 L	✅ Very Good – 6-8 hour turnover
🏊 Large in-ground	85,000-112,000 L	✅ Good – 8-hour turnover achieved
🏢 Small commercial	Up to 112,000 L	⚠️ Suitable for light-use applications

This Filter:

📍 Flow Rate: 14.0 m³/h

📍 Suitable for pools up to: 112,000 litres (with 8-hour turnover)

📍 Optimal pool size: 56,000-84,000 litres (for 4-6 hour turnover)

🔄 Maintenance Guide

Routine Maintenance:

Task	Frequency	How To
Check pressure gauge	Weekly	Note baseline reading when clean
Backwash filter	When pressure rises 0.5 bar above baseline	Run until sight glass shows clear water (5-10 minutes)
Rinse after backwash	After each backwash	Run for 30-60 seconds to settle media
Inspect seals and O-rings	Seasonally	Check lid seal and valve connections
Check media level	Annually	Top up if below recommended level
Full media replacement	Every 5-7 years	Replace entire sand charge

Pressure Gauge Guide:

📊 Clean filter baseline: Note your reading after fresh installation or backwash

📊 Backwash required: When pressure reads 0.5 bar or more above baseline

📊 Maximum safe pressure: 3.5 bar – investigate if pressure exceeds this

Backwash Procedure:

1. Turn off the pump
2. Move valve handle to “Backwash” position
3. Start pump and run for 5-10 minutes until water runs clear through sight glass
4. Stop pump and move valve to “Rinse” position
5. Run pump for 1 minute to settle sand
6. Stop pump and return valve to “Filter” position
7. Resume normal filtration

Winterisation (UK Climate):

• ❄️ Drain filter tank completely via combined drain
• ❄️ Leave drain plug loosened to prevent trapped water freezing
• ❄️ Open air relief valve to allow full drainage
• ❄️ Cover filter or relocate to frost-free storage
• ❄️ Never leave water in filter during freezing conditions

🪨 Filter Media Information

Compatible Media:

Media Type	Filtration Rating	Lifespan	Benefits
Silica Sand (#20 grade)	20-40 microns	5-7 years	Economical, proven performance
Filter Glass	5-15 microns	10+ years	Finer filtration, longer life, eco-friendly
ZeoSand (Zeolite)	3-5 microns	5 years	Superior clarity, natural ammonia reduction

Media Capacity: Approximately 150 kg of #20 silica sand

Media Recommendations:

💡 For standard residential use, high-quality silica sand provides excellent value and reliable performance.

💡 Upgrade to filter glass media for finer filtration (down to 5 microns) and reduced backwash frequency.

💡 ZeoSand offers the finest filtration and naturally absorbs ammonia and chloramines.

Signs Media Needs Replacing:

• Poor water clarity despite correct chemical balance
• Shortened filter cycles between backwashes
• Cloudy water returning to pool after filtration
• Sand channelling (water bypassing media)
• Visible degradation during inspection

🔬 Filtration Performance

Metric	Value
Filtration Rating	20-40 microns (with sand)
Filter Area	0.29 m²
Design Flow Rate	14.0 m³/h

Micron Rating Comparison:

Rating	What It Captures
40+ microns	Leaves, large debris, visible particles
20-40 microns	Sand, fine dirt, most visible matter
10-20 microns	Very fine particles, some algae spores
5-10 microns	Microscopic particles, most algae, fine sediment
Below 5 microns	Bacteria-sized particles, finest contaminants

💡 Upgrade Option: Switch to glass media to achieve 5-15 micron filtration with the same filter.

⚙️ Valve Positions & Functions

The included 6-position multiport valve provides complete control over your filtration system:

Position	Function
Filter	Normal filtration – water passes through media to pool
Backwash	Reverse flow cleans accumulated debris from media
Rinse	Settles media and clears plumbing after backwash
Waste	Bypasses filter, sends water directly to drain
Recirculate	Bypasses filter media, returns water directly to pool
Closed	Stops all water flow through valve

⚠️ Important: Always turn off the pump before changing valve positions to prevent equipment damage.

❓ Frequently Asked Questions

Q: What size pool will this filter handle?

A: The Pentair Triton TRT24 is suitable for pools up to 112,000 litres based on a standard 8-hour turnover. For optimal water quality, it performs best with pools between 56,000-84,000 litres, achieving a 4-6 hour turnover.

Q: How often do I need to backwash?

A: Backwash when the pressure gauge reads 0.5 bar above your clean baseline reading. This typically occurs every 1-2 weeks during swimming season, depending on pool usage and debris load.

Q: What filter media should I use?

A: The filter is compatible with standard #20 silica sand (most economical), filter glass (finer filtration, longer life), or ZeoSand (finest filtration). Media capacity is approximately 150 kg.

Q: How long does filter media last?

A: Silica sand typically lasts 5-7 years with proper maintenance. Glass media can last 10+ years. ZeoSand should be replaced every 5 years.

Q: What pump do I need?

A: Match the filter with a pump delivering 10.0-14.0 m³/h flow rate. Do not exceed 14.0 m³/h to prevent media damage and ensure proper filtration.

Q: Is the multiport valve included?

A: Yes, this TRT24 package includes a 6-position multiport valve with 2″ connections, pressure gauge, transparent lid, and all necessary fittings.

Q: What warranty is included?

A: Pentair provides a 10-year warranty on the filter tank shell. Contact Parts4Tubs for full warranty terms and conditions.

Q: Can I use glass media instead of sand?

A: Yes, filter glass is fully compatible and offers finer filtration (5-15 microns versus 20-40 microns with sand). Glass media is more expensive initially but lasts longer and requires less frequent backwashing.

Q: How do I winterise this filter?

A: Fully drain the tank via the combined drain, leave the drain plug loosened, and store in a frost-free location. Never allow water to freeze inside the filter tank.

Q: What makes the Triton different from other sand filters?

A: The Triton’s seamless one-piece GRP construction eliminates weld points and leak risks. The unique internal diffuser design ensures even water distribution through the sand bed, maximising filtration efficiency. Nearly 50 years of continuous refinement have made it the world’s best-selling sand filter.
