📐 Pool Sizing Guide

Sizing Principle: The filter flow rate should turn over the entire pool volume within 6-8 hours for optimal water quality.

Formula:

Maximum Pool Volume = Flow Rate × Turnover Time
8.5 m³/h × 6 hours = 51 m³ (51,000 litres)
8.5 m³/h × 8 hours = 68 m³ (68,000 litres)

Pool Size Compatibility

Pool Type	Volume Range	Suitability
🏊 Small above-ground	Up to 20,000 L	✅ Excellent – generous capacity for superior filtration
🏊 Medium above-ground	20,000-40,000 L	✅ Ideal – well-matched for optimal performance
🏊 Large above-ground	40,000-51,000 L	✅ Good – adequate turnover within 6 hours
🏠 Small in-ground	Up to 51,000 L	✅ Good – suitable for compact in-ground pools
🏠 Medium in-ground	51,000-68,000 L	⚠️ Marginal – extended 8-hour turnover

This System

📍 Filter Flow Rate: 8.5 m³/h
📍 Recommended Pool Size: Up to 51,000 litres
📍 Maximum Pool Size: Up to 68,000 litres (with 8-hour turnover)

💡 Tip: For pools between 51,000-68,000 litres, this system provides adequate filtration but consider running the pump for longer periods during peak swimming season.

Pump Compatibility Notes

This package includes a carefully matched pump and filter combination. The Aquaspeed 0.5HP pump delivers optimal flow rates for the Triton 19″ filter:

• At typical system head (6-8m), the pump delivers 7.5-10 m³/h
• This matches well with the filter’s 8.5 m³/h design flow rate
• Do not replace with a larger pump as this may exceed the filter’s maximum flow capacity

🔄 Maintenance Guide

Routine Maintenance Schedule

Task	Frequency	How To
Check pressure gauge	Weekly	Normal operating pressure varies; establish baseline when clean
Empty pump strainer basket	Weekly	Clear visible through pump lid
Backwash filter	When pressure rises 0.7-1 bar above clean baseline	Typically every 1-2 weeks during swimming season
Rinse after backwash	After each backwash	Run for 30-60 seconds until sight glass clears
Inspect seals and O-rings	Seasonally	Replace if worn, cracked, or perished
Check media level	Annually	Top up if below diffuser level
Full media replacement	Every 5-7 years (sand)	Replace completely with fresh media

Pressure Gauge Guide

📊 Clean Filter: Establish baseline (typically 0.5-0.8 bar with this system)
📊 Backwash Required: When pressure rises 0.7-1.0 bar above baseline
📊 Maximum Safe Pressure: 3.5 bar

⚠️ Never operate the filter if the pressure gauge exceeds 3.5 bar. Shut down the system and investigate the cause immediately.

Backwash Procedure

1. Turn off the pump
2. Move valve to BACKWASH position
3. Turn on pump – run until sight glass shows clear water (typically 2-3 minutes)
4. Turn off pump
5. Move valve to RINSE position
6. Turn on pump – run for 30-60 seconds
7. Turn off pump
8. Return valve to FILTER position
9. Turn on pump – resume normal filtration

Winterisation (UK Climate)

As the UK experiences freezing temperatures, proper winterisation is essential:

1. Drain the filter tank completely using the water drain
2. Remove and store the drain plug in a safe, dry location
3. Drain the pump and pipework – ensure no water remains in the system
4. Leave multiport valve in WINTERISE position (between positions to prevent seal compression)
5. Cover equipment or store in a frost-free location if possible
6. Never leave water in the filter or pump during freezing conditions – ice expansion can crack the tank and pump housing

🪨 Filter Media Information

Compatible Media Types

Media Type	Filtration Rating	Lifespan	Benefits
Pool Grade Sand	20-40 microns	5-7 years	Traditional, economical choice
Glass Media	5-15 microns	10+ years	Finer filtration, longer lasting, eco-friendly
ZeoSand / Zeolite	3-5 microns	5 years	Superior water clarity, ammonia removal
PureFlow Fibre	Sub-1 micron	3-5 years	Exceptional clarity, lightweight, easy handling

Media Capacity Requirements

For Triton 19″ Filter:

• Sand: 52 kg (Grade 16/30 silica sand, 0.4-0.8mm)
• Gravel (support layer): 20 kg
• Glass Media Alternative: Approximately 37 kg (70% of sand weight)
• PureFlow Alternative: 1 kg only

💡 Recommendation: Glass filter media provides significantly finer filtration (5-15 microns vs 20-40 microns with sand) and lasts approximately twice as long. While the initial cost is higher, reduced backwash frequency and extended lifespan often make it more economical over time.

Signs Media Needs Replacing

• Poor water clarity despite correct chemical balance
• Short filter cycles between backwashes
• Increased backwash frequency needed
• Sand visible in pool returns
• Filter pressure won’t drop after backwashing

🔬 Filtration Performance

Performance Metric	Value
Filtration Rating (Sand)	20-40 microns
Filtration Rating (Glass)	5-15 microns
Filter Area	0.17 m²
Design Flow Rate	8.5 m³/h

Micron Rating Guide

Rating	What It Catches
40+ microns	Visible debris, leaves, large particles
20-40 microns	Sand, dirt, visible particles, larger algae
10-20 microns	Fine particles, most algae, pollen
5-10 microns	Very fine particles, bacteria clumps, algae spores
Below 5 microns	Microscopic particles, improved water sparkle

The Triton filter’s special internal design keeps the sand bed level, preventing channelling and ensuring all water receives maximum filtration. Combined with the even flow from the Aquaspeed pump, this system delivers consistent, reliable water clarity.

⚙️ Valve Positions & Functions

The six-position multiport valve provides complete control over water flow:

Position	Function
FILTER	Normal filtration – water flows through media and returns to pool
BACKWASH	Reverses water flow to flush debris from media to waste
RINSE	Settles media and clears residual debris after backwash
WASTE	Bypasses filter, sends water directly to waste (for lowering water level)
RECIRCULATE	Bypasses filter media, circulates water through pump and returns to pool
CLOSED	Stops all water flow through valve

⚠️ Important: Always turn off the pump before changing valve positions. Moving the valve with the pump running can damage internal components.

❓ Frequently Asked Questions

Q: What size pool will this filter and pump combination handle? A: This system is suitable for pools up to approximately 51,000 litres with a standard 6-hour turnover, or up to 68,000 litres with an extended 8-hour turnover. The 8.5 m³/h flow rate provides efficient filtration for most above-ground and smaller in-ground pools.

Q: How often do I need to backwash? A: Backwash when the pressure gauge reads 0.7-1.0 bar above your clean filter baseline. This is typically every 1-2 weeks during the swimming season, though frequency depends on pool usage, debris load, and environmental factors.

Q: What filter media should I use? A: This filter can use standard pool grade sand (52 kg plus 20 kg gravel), glass media (approximately 37 kg), ZeoSand, or PureFlow fibre (1 kg). Glass media offers finer filtration and longer lifespan, making it an excellent upgrade option.

Q: How long does filter media last? A: Sand typically lasts 5-7 years with proper maintenance. Glass media can last 10+ years. ZeoSand and PureFlow have 3-5 year lifespans depending on usage.

Q: Can I use this system with a salt chlorinator? A: Yes, both the Triton filter and Aquaspeed pump are designed for use with salt chlorinated pools. The 316 grade stainless steel pump shaft and corrosion-resistant materials ensure long-term durability.

Q: What warranty is included? A: The Pentair Triton filter tank has a 10-year limited warranty. The Certikin Aquaspeed pump has a 2-year warranty (1 year on mechanical seal and capacitor). Contact Parts4Tubs for full warranty terms and conditions.

Q: Do I need to buy anything else? A: This is a complete package including filter, multiport valve, pressure gauge, and pump. You will need to purchase filter media separately (sand, glass media, or alternative) plus appropriate plumbing fittings for your installation.

Q: Can I install this myself? A: The filter and pump can be installed by competent DIY enthusiasts. However, all electrical connections must be completed by a qualified electrician. If you’re unsure about any aspect of installation, we recommend using a professional installer.

Q: How quiet is the pump? A: The Aquaspeed pump features an IP55 totally enclosed fan cooled motor which runs quietly during normal operation. The hydraulically efficient impeller design minimises turbulence, reducing operational noise.
