📏 Pool Sizing Guide
Sizing Principle: The filter flow rate should turn over the entire pool volume within 6–8 hours for optimal water clarity and hygiene.
Formula:
Required Flow Rate (m³/h) = Pool Volume (m³) ÷ Turnover Time (hours)
Pool Size Compatibility:
| Pool Type | Volume Range | Suitability |
|---|---|---|
| 🏠 Large above-ground | 60,000–100,000 L | ✅ Excellent – oversized capacity ensures crystal clear water |
| 🏊 Medium in-ground | 80,000–130,000 L | ✅ Ideal – perfect balance of flow and turnover time |
| 🏊 Large in-ground | 130,000–176,000 L | ✅ Suitable – achieves 8-hour turnover at maximum capacity |
| 🏢 Small commercial | Up to 132,000 L | ✅ Recommended – meets 6-hour commercial turnover requirements |
This Filter:
📍 Flow Rate: 22.0 m³/h (22,000 litres per hour)
📍 Suitable for pools up to: 176,000 litres (8-hour turnover) or 132,000 litres (6-hour turnover)
🔌 Installation Requirements
Plumbing:
| Requirement | Specification |
|---|---|
| Inlet Connection | 50 mm (2″) |
| Outlet Connection | 50 mm (2″) |
| Valve Position | Side mount |
| Pipe Material | PVC recommended |
Physical Installation:
| Requirement | Details |
|---|---|
| Base | Solid, level surface required (concrete slab or platform recommended) |
| Clearance Above | Minimum 1060 mm for lid removal and servicing |
| Clearance Around | Minimum 500 mm for valve operation and maintenance access |
| Location | Dry, well-ventilated area with adequate drainage |
Pump Compatibility:
⚠️ The filter must be matched with an appropriately sized pump.
Recommended pump flow rate: 18–22 m³/h
The pump flow rate must not exceed the filter’s maximum flow rate of 22.0 m³/h. Oversized pumps can cause channelling through the sand bed, reducing filtration efficiency.
🔄 Maintenance Guide
Routine Maintenance:
| Task | Frequency | Procedure |
|---|---|---|
| Check pressure gauge | Weekly | Note baseline reading; normal operating range varies by installation |
| Backwash filter | When pressure rises 0.5 bar above baseline | Run backwash cycle for 5–10 minutes until sight glass shows clear water |
| Rinse after backwash | After each backwash | Run rinse cycle for approximately 1 minute |
| Inspect seals and O-rings | Seasonally | Check for wear and replace if damaged |
| Check media level | Annually | Top up sand if level has dropped below freeboard requirements |
| Full media replacement | Every 5 years | Replace all sand and pea gravel |
Pressure Gauge Guide:
📊 Clean filter baseline: Note reading after fresh backwash (record this for reference)
📊 Backwash required: When pressure rises 0.5 bar above baseline
📊 Maximum operating pressure: 3.5 bar
Winterisation (UK Climate):
- Drain filter tank completely using the combined sand and water drain
- Turn drain tap 180° to open position (do not fully unscrew)
- Open air relief valve to ensure complete drainage
- Remove and store drain plugs safely
- Cover filter or relocate to frost-free storage if possible
- Never leave water in the filter during freezing conditions – ice expansion can crack the tank
🪨 Filter Media Information
Compatible Media:
| Media Type | Filtration Rating | Lifespan | Benefits |
|---|---|---|---|
| Silica Sand (#20 grade) | 20–40 microns | 5–7 years | Economical, proven performance, widely available |
| Glass Media | 5–15 microns | 10+ years | Finer filtration, longer life, lighter weight |
| ZeoSand/Zeolite | 3–5 microns | 5 years | Superior water clarity, removes ammonia |
Media Capacity:
- Sand: 200 kg
- Pea Gravel (base layer): 75 kg
- Total: 275 kg
💡 Tip: Use #20 grade silica sand (0.45–0.55 mm particle size) for optimal performance. Glass media alternatives like AFM or FilterGlass offer enhanced filtration down to 5 microns.
Signs Media Needs Replacing:
- Consistently poor water clarity despite correct chemical balance
- Short filter cycles requiring frequent backwashing
- Cloudy water returning to pool after filtration
- Sand appearing in pool (indicates damaged lateral)
- Media clumping or channelling visible through clear lid
🔬 Filtration Performance
| Metric | Value |
|---|---|
| Standard Filtration Rating | 20–40 microns (with sand media) |
| Filter Area | 0.45 m² |
| Flow Rate | 22.0 m³/h |
Micron Rating Guide:
| Rating | What It Captures |
|---|---|
| 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, all algae |
💡 Upgrade Option: Install glass media instead of sand to achieve filtration down to 5–15 microns for enhanced water clarity.
⚙️ Valve Positions & Functions
| Position | Function |
|---|---|
| Filter | Normal filtration mode – water passes through sand bed and returns to pool |
| Backwash | Reverses water flow to flush debris from sand to waste |
| Rinse | Settles sand bed after backwash; run for 1 minute before returning to filter mode |
| Waste | Bypasses filter and sends water directly to drain – use for vacuuming heavy debris |
| Recirculate | Bypasses filter but returns water to pool – use when treating water chemically |
| Closed | Stops all water flow through the valve |
⚠️ Important: Always switch off the pump before changing valve position to prevent damage to the multiport valve and seals.
🎯 Ideal Applications
| Application | Pool Size | Suitability |
|---|---|---|
| 🏠 Large residential above-ground | 60,000–100,000 L | Excellent – provides generous capacity for crystal clear water |
| 🏠 Large residential in-ground | 80,000–176,000 L | Ideal – designed for substantial private pools |
| 🏢 Small commercial/holiday let | Up to 132,000 L | Recommended – meets 6-hour commercial turnover requirements |
| 🏊 Swim spas and exercise pools | All sizes | Excellent – high flow rate handles intensive use |
❓ Frequently Asked Questions
Q: What size pool will this filter handle?
A: The Pentair Triton TRT30 is suitable for pools up to 176,000 litres with an 8-hour turnover, or 132,000 litres with a 6-hour turnover. The 22.0 m³/h flow rate provides excellent filtration for large residential and small commercial pools.
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 depending on pool usage, debris load, and bather numbers.
Q: What filter media should I use?
A: The filter is compatible with #20 silica sand (200 kg) with a 75 kg pea gravel base layer. For enhanced filtration, consider glass media alternatives which filter down to 5–15 microns and last longer.
Q: How long does filter media last?
A: Standard silica sand should be replaced every 5 years. Glass media typically lasts 10+ years. Check media condition annually and replace sooner if water clarity deteriorates or backwash cycles become unusually frequent.
Q: What pump do I need?
A: Match with a pump delivering 18–22 m³/h. The pump flow rate should not exceed 22.0 m³/h to prevent channelling through the sand bed. Ensure the pump’s head pressure is compatible with your plumbing system.
Q: Is the multiport valve included?
A: Yes, the TRT30 is supplied complete with a 6-position multiport valve and connections, ready for installation.
Q: What warranty is included?
A: Pentair provides a 10-year limited 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, glass media such as AFM or FilterGlass is fully compatible and provides finer filtration (5–15 microns versus 20–40 microns for sand). Glass media is lighter, so you may need to adjust quantities – typically 15–20% less by weight than sand.
