 Pool Sizing Guide

Proper filter sizing ensures your pool water is fully circulated and cleaned within the recommended 6-8 hour turnover period. This maintains optimal water clarity and hygiene whilst reducing chemical consumption.

Sizing Formula:

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

Example Calculations:

Pool Volume	6-Hour Turnover	8-Hour Turnover
12,000 L (12 m³)	2.0 m³/h needed	1.5 m³/h needed
18,000 L (18 m³)	3.0 m³/h needed	2.25 m³/h needed
24,000 L (24 m³)	4.0 m³/h needed	3.0 m³/h needed
36,000 L (36 m³)	6.0 m³/h needed	4.5 m³/h needed

Pool Size Compatibility:

Pool Type	Volume Range	Suitability	Notes
Small above-ground	Up to 12,000 L	Excellent	Achieves fast 4-hour turnover
Medium above-ground	12,000-18,000 L	Excellent	Achieves optimal 6-hour turnover
Large above-ground	18,000-24,000 L	Very good	Achieves 6-8 hour turnover
Small in-ground	Up to 20,000 L	Good	Suitable with moderate pipework
Medium in-ground	20,000-24,000 L	Adequate	Maximum recommended capacity
Intex/Bestway pools	10,000-24,000 L	Ideal	Perfect upgrade from cartridge

This Filter Pack:

 Design Flow Rate: 6 m³/h
 Maximum Pump Capacity: 11 m³/h
 Recommended Pool Size: Up to 24,000 litres (medium resistance)
 Maximum Pool Size: Up to 46,000 litres (low resistance)

 Filter Media Installation

Media Layering (Critical for Proper Filtration)

The filter requires two layers of media installed in the correct order:

Layer 1: Gravel Bed (Bottom)

Specification	Value
Media Type	Gravel/pea shingle
Grain Size	3-5 mm diameter
Quantity Required	12 kg
Purpose	Supports sand bed, prevents lateral clogging

Layer 2: Filter Sand (Top)

Specification	Value
Media Type	Pool filter sand (silica)
Grain Size	0.4-0.8 mm (fine grade)
Quantity Required	30 kg
Purpose	Primary filtration medium

Installation Procedure

1. Inspect laterals – Check all 6 filter nozzles are secure and undamaged
2. Fill tank 1/3 with water – Protects laterals during media filling
3. Position sand guide – Place over central pipe to direct sand away from laterals
4. Add gravel first – Pour 12kg evenly around the laterals
5. Add sand on top – Pour 30kg evenly, keeping sand guide in place
6. Remove sand guide – Lift out carefully
7. Level media surface – Ensure even distribution
8. Leave 150mm freeboard – Space for bed expansion during backwash

 Critical: Never operate the filter without both gravel and sand correctly installed. Running without media will damage the laterals and void the warranty.

 Frequently Asked Questions

Sizing & Compatibility

Q: What size pool will this filter handle? A: This system is designed for pools up to 24,000 litres at medium resistance, or up to 46,000 litres with very short, direct pipework (low resistance). With a design flow rate of 6 m³/h, it achieves the recommended 6-8 hour complete water turnover for optimal filtration.

Q: Can I use this filter with a larger pump? A: The system is optimised with the included 0.33hp FreeFlo pump. Using a larger pump could exceed the filter’s maximum flow rate and working pressure, potentially damaging the equipment and voiding the warranty.

Q: Is this suitable for saltwater pools? A: Yes, all components including the pump housing, filter tank, and valve are resistant to saltwater pool environments up to standard chlorinator salt levels (typically 3,000-6,000 ppm).

Filter Media

Q: What filter media should I use? A: The filter requires 12kg of gravel (3-5mm) as a base layer, plus 30kg of filter sand (0.4-0.8mm). Alternatively, use 27kg of filter glass for improved filtration performance.

Q: How long does filter media last? A: Standard pool sand typically lasts 5-7 years with proper maintenance. Glass media can last 10-15 years. Replace earlier if water clarity deteriorates despite correct chemical balance and regular backwashing.

Q: Is filter media included? A: No, filter media is sold separately. This allows you to choose your preferred media type based on your filtration requirements and budget.

Operation & Maintenance

Q: How often do I need to backwash? A: Backwash when the pressure gauge reads 0.3-0.5 bar above your clean baseline reading. This typically occurs every 1-2 weeks during normal use, though frequency increases with heavy bather loads, algae issues, or high debris levels.

Q: What’s the normal pressure gauge reading? A: A clean filter typically shows 0.5-0.8 bar. Normal operating range is 0.8-1.2 bar. Backwash when pressure rises to 1.2-1.5 bar (0.3-0.5 bar above your specific baseline).

Q: Can I run the pump 24/7? A: Yes, the pump is designed for continuous operation. However, most residential pools achieve excellent water quality with 8-12 hours of daily filtration, reducing electricity costs.

Installation

Q: Is the pump self-priming? A: Yes, the FreeFlo FFL-031 pump is fully self-priming up to 2 metres of lift, allowing installation either above or below water level. Optimal performance is achieved when positioned 5-10 metres from the pool with minimal pipework bends.

Q: How long does installation take? A: For a DIY installation, allow 2-4 hours including pipework connections. The pre-assembled pump and filter on the unified base significantly reduces setup time compared to separate components.

Q: Do I need a concrete base? A: A solid, level surface is essential. Concrete slabs or paving stones work well. Avoid placing directly on soil, grass, or unstable surfaces that could shift and stress connections.

Warranty & Support

Q: What warranty is included? A: The filter vessel carries a 5-year manufacturer warranty, the pump has a 2-year warranty, and the multiport valve is covered for 1 year. Contact Parts4Tubs for full warranty terms and conditions.

Q: Where can I get spare parts? A: All spare parts including O-rings, valve gaskets, laterals, pump seals, and strainer baskets are available from Parts4Tubs and authorised Pentair stockists.
