📏 Pool Sizing Guide

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

Formula:

Pool Volume (litres) = Flow Rate (m³/h) × Turnover Time (hours) × 1000

Pool Size Compatibility:

Pool Type	Volume Range	Suitability
🏠 Medium above-ground	30,000 – 50,000 L	✅ Excellent – optimal performance
🏠 Large above-ground	50,000 – 65,000 L	✅ Very good – ideal 6-hour turnover
🏊 Small in-ground	40,000 – 60,000 L	✅ Excellent – well matched
🏊 Medium in-ground	60,000 – 86,000 L	✅ Good – suitable with 8-hour turnover
🏊 Large in-ground	86,000+ L	⚠️ Consider larger filter model

This Filter:

📍 Normal Filtration Flow Rate: 10.8 m³/h (at 30 m³/h/m²)
📍 Maximum Backwash Flow Rate: 18 m³/h (at 50 m³/h/m²)
📍 Optimal Pool Size: Up to 65,000 litres (6-hour turnover)
📍 Maximum Pool Size: Up to 86,400 litres (8-hour turnover)

⚙️ Installation Requirements

Plumbing:

Requirement	Specification
Inlet Connection	2″ (50 mm) female thread
Outlet Connection	2″ (50 mm) female thread
Valve Position	Top mount

Physical Installation:

Requirement	Details
Base	Solid, level concrete or paving slab required
Clearance Above	Minimum 500 mm for valve handle operation
Clearance Around	Minimum 300 mm for maintenance access
Location	Well-ventilated area, protected from direct sunlight if possible

Pump Compatibility:

⚠️ The filter must be matched with an appropriate pump for optimal performance.

• Recommended pump flow rate: 8 – 16 m³/h
• Maximum pump flow rate: Do not exceed 18 m³/h
• Pump must be positioned below pool water level or be self-priming
• Ensure pump flow rate is compatible with filter’s backwash requirements

💡 Tip: Matching your pump to the filter’s normal filtration rate (10.8 m³/h) rather than maximum backwash rate ensures efficient daily operation and extends equipment lifespan.

🔄 Maintenance Guide

Routine Maintenance:

Task	Frequency	Procedure
Check pressure gauge	Weekly	Note baseline reading when filter is clean
Backwash filter	When pressure rises 0.5-0.8 bar above clean baseline	Run until sight glass shows clear water (typically 2-3 minutes)
Rinse after backwash	After every backwash	Run for 30-60 seconds to settle media
Inspect valve seals	Seasonally	Check for wear, cracks, or leaks
Check media level	Annually	Top up if level has dropped below 2/3 mark
Full media replacement	Every 5-7 years (sand)	Replace completely when water clarity declines

Pressure Gauge Guide:

📊 Clean filter baseline: Approximately 0.5 – 1.0 bar
📊 Backwash required: When 0.5 – 0.8 bar above baseline
📊 Maximum safe operating: 2.5 bar

⚠️ Important: Never exceed the maximum working pressure of 2.5 bar. If pressure remains high after backwashing, inspect media for channelling or calcification.

Winterisation (UK Climate):

For UK pool owners, proper winterisation is essential to prevent frost damage:

1. Switch off pump and set valve to “Closed” position
2. Drain filter tank completely via drain plug
3. Remove and store drain plug safely indoors
4. Leave valve handle in “Winterise” position (between settings) if available
5. Cover filter or relocate to frost-free storage area
6. Never leave water in filter during freezing conditions – expanding ice can crack the tank

💡 Tip: Apply a small amount of silicone lubricant to valve O-rings before winterisation to prevent drying and cracking.

🪨 Filter Media Information

Compatible Media:

Media Type	Filtration Rating	Lifespan	Benefits
Silica Sand (#16 grade)	20-40 microns	5-7 years	Economical, proven performance, widely available
Glass Media	5-15 microns	10+ years	Finer filtration, reduced backwashing, eco-friendly
ZeoSand/Zeolite	3-5 microns	5-7 years	Superior water clarity, reduces chloramine odours

Media Capacity:

• Sand: 175 kg
• Gravel (support layer): 140 kg

💡 Important: Always install gravel layer first as a support bed before adding sand. The gravel layer prevents sand from entering the filter laterals and ensures even water distribution.

Signs Media Needs Replacing:

• Poor water clarity despite correct chemical balance
• Shortened filter cycles (frequent backwashing required)
• Cloudy water returns to pool after filtration
• Visible channelling or clumping in media bed
• Filter media is more than 7 years old

🔬 Filtration Performance

Metric	Value
Filtration Rating (Sand)	20-40 microns
Filter Area	0.36 m²
Media Bed Depth	Approximately 400-450 mm

Micron Rating Guide:

Rating	What It Captures
40+ microns	Large visible debris, leaves, insects
20-40 microns	Sand, dirt, larger algae cells, skin cells
10-20 microns	Fine particles, pollen, smaller algae
5-10 microns	Very fine suspended particles, most bacteria clumps
Below 5 microns	Microscopic particles (requires D.E. or glass media)

💡 Upgrade Tip: For enhanced water clarity, consider replacing standard sand with glass media, which can filter down to 5-15 microns whilst reducing backwash frequency by up to 50%.

🛠️ Valve Positions & Functions

The included Praher 6-way multiport valve provides complete control over your filter operations:

Position	Function
Filter	Normal filtration mode – water flows through media and returns clean to pool
Backwash	Reverses water flow to flush trapped debris out through waste line
Rinse	Settles media bed after backwash – run for 30-60 seconds before returning to Filter
Waste	Bypasses filter media – pumps water directly to waste for lowering pool level or vacuuming heavy debris
Recirculate	Bypasses filter – circulates water without filtration (useful when adding chemicals)
Closed	Stops all water flow – use for winterisation or equipment maintenance

⚠️ Safety Warning: Always stop the pump before changing valve positions. Turning the valve whilst the pump is running can damage internal seals and components.

❓ Frequently Asked Questions

Q: What size pool will this filter handle?

A: The PPG Filter Top 680 is suitable for pools up to 86,400 litres with an 8-hour turnover time, or up to 64,800 litres for optimal 6-hour turnover performance. The normal filtration flow rate is 10.8 m³/h.

Q: How often do I need to backwash the filter?

A: Backwash when the pressure gauge reads 0.5-0.8 bar above the clean baseline reading. This is typically every 1-2 weeks during the swimming season, depending on pool usage and environmental debris levels.

Q: What filter media should I use?

A: The filter is compatible with standard silica sand (175 kg capacity), glass media, or zeolite. Sand provides 20-40 micron filtration, whilst glass media can achieve 5-15 micron filtration for enhanced clarity.

Q: How long does the filter media last?

A: Silica sand typically lasts 5-7 years with proper maintenance. Glass media can last 10+ years due to its harder composition and resistance to degradation.

Q: What pump do I need for this filter?

A: Match with a pump delivering 8-16 m³/h for optimal performance. Ensure the pump does not exceed the filter’s maximum flow rate of 18 m³/h. Variable speed pumps offer energy savings and longer equipment life.

Q: What warranty is included?

A: The PPG Filter Top 680 comes with a 5-year manufacturer warranty on the tank. Contact Parts4Tubs for full warranty terms and conditions.

Q: Can I use glass media instead of sand?

A: Yes, glass media is fully compatible and offers several advantages including finer filtration (5-15 microns), longer lifespan, and reduced backwash frequency. Use approximately 15-20% less glass media by weight compared to sand.

Q: How do I winterise the filter for UK winters?

A: Drain the tank completely, remove the drain plug for storage, set the valve to the winterise position, and either cover the filter or store in a frost-free location. Never leave water in the filter during freezing conditions.

Q: What is the difference between the PPG Filter Top range sizes?

A: The PPG Filter Top range includes 400mm, 510mm, 620mm, 680mm, 750mm, and 900mm diameter models. Larger diameters offer greater filter area and flow capacity for bigger pools. The 680mm model is ideal for medium to large residential pools.

Q: Does this filter come with everything I need?

A: Yes, the PPG Filter Top 680 V6 includes the filter tank, Praher 6-way multiport valve, pressure gauge, and internal diffuser. You will need to purchase filter media (sand/glass), plumbing fittings, and a compatible pump separately.
