📏 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. A 6-hour turnover represents the recommended standard for busy pools, whilst 8 hours is acceptable for pools with lighter usage.

Formula:

Maximum Pool Volume = Flow Rate × Turnover Time
Example: 19.2 m³/h × 6 hours = 115.2 m³ (115,200 litres)
Example: 19.2 m³/h × 8 hours = 153.6 m³ (153,600 litres)

Pool Size Compatibility:

Pool Type	Volume Range	Suitability
🏊 Medium In-Ground	50,000 – 80,000 L	Excellent – optimal turnover with capacity to spare
🏊 Large In-Ground	80,000 – 115,000 L	Ideal – perfect sizing for 6-hour turnover
🏊 Very Large In-Ground	115,000 – 150,000 L	Good – suitable with 8-hour turnover
🏠 Large Above-Ground	40,000 – 60,000 L	Excellent – significant oversizing provides superior clarity
🏠 Extra Large Above-Ground	60,000 – 80,000 L	Excellent – ideal match for premium filtration

This Filter:

📍 Optimal Flow Rate: 19.2 m³/h (at recommended 30 m³/h/m² filtration velocity)

📍 Backwash Flow Rate: 32 m³/h (at 50 m³/h/m² for thorough media cleaning)

📍 Recommended Pool Size: 80,000 – 115,000 litres (6-hour turnover)

📍 Maximum Pool Size: Up to 150,000 litres (8-hour turnover)

🔄 Maintenance Guide

Routine Maintenance Schedule:

Task	Frequency	Method
Check pressure gauge	Weekly	Record baseline and monitor for increases
Backwash filter	When pressure rises 0.5-0.7 bar above baseline	Run until sight glass runs clear (typically 2-3 minutes)
Rinse after backwash	After every backwash	Run for 30-60 seconds to settle media
Inspect valve o-rings and seals	Every 3-6 months	Replace if worn, cracked or leaking
Check media level	Annually at season start	Top up if settled below recommended level
Full media replacement	Every 5-7 years (sand)	Replace entire bed for optimal filtration

Pressure Gauge Guide:

📊 Clean filter baseline: Typically 0.5 – 0.8 bar (varies by installation)

📊 Backwash required: When pressure rises 0.5 – 0.7 bar above clean baseline

📊 Maximum safe operating pressure: 2.5 bar

⚠️ Warning: If pressure exceeds 2.5 bar or does not reduce after backwashing, investigate for blockages or media issues immediately.

Winterisation Procedures (UK Climate):

British winters can bring freezing temperatures that may damage filter equipment. Follow these essential steps:

1. Drain the filter tank completely – Open the drain plug and ensure all water is removed
2. Remove and store the drain plug – Keep in a safe, dry location to prevent loss
3. Disconnect pipework where possible – Or ensure all connected pipes are also drained
4. Cover or relocate – Cover the filter or ideally store in a frost-free location such as a garage or shed
5. Never leave water in the filter – Ice expansion can crack the tank and damage internal components

💡 Tip: Schedule winterisation before the first frost, typically October-November in most UK regions.

🪨 Filter Media Information

Compatible Filter Media:

Media Type	Filtration Rating	Lifespan	Key Benefits
Silica Sand	20-40 microns	5-7 years	Economical, widely available, proven performance
Glass Media (AFM/PPG)	5-15 microns	10+ years	Superior clarity, longer life, reduced backwashing
ZeoSand/Zeolite	3-5 microns	5 years	Excellent ammonia removal, finest filtration

Media Capacity for PPG Filter Top 900:

Media	Quantity Required
Sand	350 kg
Gravel (support bed)	280 kg
Total Media Weight	630 kg

⚠️ Important: Always install the gravel support bed first, then add sand media. The gravel layer prevents sand from entering the lateral system and ensures even water distribution.

Signs Your Filter Media Needs Replacing:

• Persistent poor water clarity despite correct chemical balance
• Significantly shorter filter cycles between backwashing
• Cloudy water returns to pool immediately after filtration
• Filter requires backwashing more than twice weekly during normal use
• Media has been in service for more than 7 years (sand) or 12+ years (glass)

💎 Filtration Performance

Metric	Value
Filtration Rating (Sand)	20-40 microns
Filtration Rating (Glass Media)	5-15 microns
Filter Area	0.64 m²
Filtration Velocity	30 m³/h/m² (recommended)
Flow Rate	19.2 m³/h

Understanding Micron Ratings:

Rating	What It Captures
40+ microns	Visible debris, leaves, larger insects
20-40 microns	Sand, dirt, visible particles, hair
10-20 microns	Fine particles, some algae, pollen
5-10 microns	Very fine particles, most algae, bacteria colonies
Under 5 microns	Extremely fine matter (requires glass media or DE filter)

💡 Upgrade Tip: Replacing standard sand with glass filter media such as AFM can improve filtration from 20-40 microns down to 5-15 microns, delivering noticeably clearer water with the same filter.

⚙️ Valve Positions & Functions

The included Praher 6-way multiport valve provides complete control over water flow:

Position	Function	When to Use
Filter	Normal filtration – water flows through media and returns to pool	Daily operation
Backwash	Reversed flow cleans debris from media and sends to waste	When pressure gauge rises 0.5-0.7 bar above baseline
Rinse	Forward flow settles media after backwashing	30-60 seconds after every backwash
Waste	Bypasses filter media, sends water directly to waste	Vacuuming heavy debris, lowering water level
Recirculate	Bypasses filter media, returns water to pool	Distributing chemicals quickly, heating water faster
Closed	Stops all water flow through valve	Pump maintenance, equipment inspection

⚠️ Warning: Never operate the multiport valve whilst the pump is running. Always switch off the pump before changing valve positions to prevent damage to the valve seal.

❓ Frequently Asked Questions

Q: What size pool will this filter handle?

A: The PPG Filter Top 900 is suitable for pools up to approximately 115,000 litres with a 6-hour turnover (recommended), or up to 150,000 litres with an 8-hour turnover. The 19.2 m³/h flow rate at optimal filtration velocity ensures thorough water circulation.

Q: How often do I need to backwash?

A: Backwash when the pressure gauge reads 0.5-0.7 bar above your clean filter baseline reading. Under normal conditions, this is typically every 1-2 weeks during swimming season. More frequent backwashing may be needed during periods of heavy use, algae treatment, or high debris load.

Q: What filter media should I use?

A: The filter is compatible with silica sand (350 kg), glass media, or zeolite. Sand is economical and effective, whilst glass media such as AFM provides finer filtration (5-15 microns vs 20-40 microns) and lasts longer. A 280 kg gravel support bed is also required.

Q: How long does the filter media last?

A: Standard silica sand typically lasts 5-7 years before requiring replacement. Glass filter media can last 10+ years due to its resistance to biological fouling and superior hardness. Replace media when you notice persistent water clarity issues despite proper maintenance.

Q: What pump do I need with this filter?

A: Select a pump capable of delivering 15-19 m³/h for normal filtration, with sufficient power for 25-32 m³/h during backwashing. Variable speed pumps are ideal as they can operate efficiently at lower speeds for daily filtration whilst providing full power when backwashing. Never exceed the filter’s maximum flow rate of 32 m³/h.

Q: What warranty is included?

A: The PPG Filter Top 900 includes a comprehensive 5-year warranty on the tank. The Praher multiport valve is covered separately. Contact Parts4Tubs for complete warranty terms and conditions.

Q: Can I use glass media instead of sand?

A: Absolutely. The filter is fully compatible with glass media alternatives such as AFM (Activated Filter Media) or PPG Glass Filter Media. Glass media provides finer filtration, requires less frequent backwashing, and typically lasts twice as long as sand. You may need slightly less glass media by volume than sand – check manufacturer recommendations.

Q: Is this filter suitable for saltwater pools?

A: Yes. The glass fibre reinforced polyester construction is fully compatible with saltwater chlorination systems. Ensure all connected plumbing and fittings are also suitable for saltwater use.

Q: How do I winterise this filter?

A: Drain the tank completely through the drain plug, remove and store the plug safely, and either cover the filter or store in a frost-free location. Never leave water in the filter during freezing conditions as ice expansion can crack the tank and damage internal components.

Q: What is the difference between the Top 900 and Side 900 models?

A: Both filters have identical filtration capacity and tank specifications. The difference is the valve mounting position – the Top 900 has the multiport valve mounted on top of the tank, whilst the Side 900 has a side-mounted valve. Top mount is generally easier for standard installations, whilst side mount may be preferred where overhead clearance is limited.
