📏 Pool Sizing Guide
Sizing Principle:
Your filter’s flow rate should turn over the entire pool volume within 6-8 hours for optimal water quality.
Formula:
Pool Capacity (litres) = Flow Rate (m³/h) × Turnover Time (hours) × 1000
This Filter’s Capacity:
📍 Flow Rate: 22 m³/h
📍 6-Hour Turnover: Suitable for pools up to 132,000 litres
📍 8-Hour Turnover: Suitable for pools up to 176,000 litres
Pool Size Compatibility:
| Pool Type | Volume Range | Suitability |
|---|---|---|
| 🏊 Large above-ground | 40,000-60,000 L | Excellent – generous capacity margin |
| 🏠 Medium in-ground | 50,000-80,000 L | Ideal match with optimal turnover |
| 🏠 Large in-ground | 80,000-130,000 L | Well suited for 6-8 hour cycles |
| 🏠 Very large in-ground | 130,000-175,000 L | Suitable with 8-hour turnover |
| 🏢 Small commercial | Up to 130,000 L | Good choice for light commercial use |
💡 Tip: For best water quality, select a filter that can turn over your pool volume in 6 hours rather than 8, providing a comfortable safety margin.
🛠️ Installation Requirements
Plumbing Connections:
| Requirement | Specification |
|---|---|
| Inlet Connection | 2″ (50 mm) |
| Outlet Connection | 2″ (50 mm) |
| Valve Position | Top Mount |
| Pipework | 50 mm / 2″ compatible |
Physical Installation:
| Requirement | Details |
|---|---|
| Base | Solid, level concrete or paving slab required |
| Clearance Above | Minimum 500 mm for valve operation and lid removal |
| Clearance Around | Minimum 300 mm for maintenance access |
| Location | Sheltered, well-ventilated area preferred |
Pump Compatibility:
⚠️ Important: The filter must be matched with an appropriately sized pump.

- Maximum flow rate: Do not exceed 22 m³/h
- Pump must generate sufficient head pressure to overcome filter resistance
- Match pipe diameter to 2″ connections for optimal flow
🔄 Maintenance Guide
Routine Maintenance:
| Task | Frequency | Procedure |
|---|---|---|
| Check pressure gauge | Weekly | Note baseline and monitor for increases |
| Backwash filter | When pressure rises 0.5-1.0 bar above baseline | Run until sight glass shows clear water |
| Rinse after backwash | After every backwash | Run for 30-60 seconds to settle media |
| Inspect seals and O-rings | Seasonally | Check for wear, replace if damaged |
| Check media level | Annually | Top up if level has dropped |
| Full media replacement | Every 5-7 years | Replace sand completely |
Pressure Gauge Guide:
📊 Clean filter baseline: 0.5-1.0 bar (note your specific reading)
📊 Backwash required: When 0.5-1.0 bar above your baseline
📊 Maximum safe operating: 2.5 bar
⚠️ Warning: If pressure exceeds 2.5 bar, stop the pump immediately and investigate the cause.
Winterisation (UK Climate):
For pools that will not be used during winter months:
- Drain the filter tank completely using the drain plug
- Remove and safely store the drain plug to prevent water accumulation
- Consider covering the filter or relocating to a frost-free area
- Never leave standing water in the filter during freezing conditions
- Inspect all seals before recommissioning in spring
🪨 Filter Media Information
Compatible Media:
| Media Type | Filtration Rating | Typical Lifespan | Key Benefits |
|---|---|---|---|
| Silica Sand (#16) | 20-40 microns | 5-7 years | Economical, proven performance |
| Glass Media | 5-15 microns | 10+ years | Finer filtration, eco-friendly |
| ZeoSand/Zeolite | 3-5 microns | 5 years | Superior clarity, ammonia removal |
Media Requirements:
- Sand capacity: 175 kg
- Gravel base layer: 50 kg (required beneath sand)
- Total media weight: 225 kg
Signs Media Needs Replacing:
- Persistent cloudy water despite correct chemical balance
- Very short filter cycles between backwashes
- Sand or media particles visible in pool water
- Filter pressure remains high even after backwashing
- Media has become compacted or channelled
🔬 Filtration Performance
| Metric | Value |
|---|---|
| Flow Rate | 22 m³/h |
| Filtration Area | 0.45 m² |
| Filtration Velocity | 50 m³/h/m² |
| Filtration Rating (Sand) | 20-40 microns |
| Filtration Rating (Glass) | 5-15 microns |
Micron Rating Guide:
| Rating | What It Captures |
|---|---|
| 40+ microns | Visible debris, leaves, large particles |
| 20-40 microns | Sand, dirt, visible suspended particles |
| 10-20 microns | Fine particles, some algae spores |
| 5-10 microns | Very fine particles, most algae, superior clarity |
💡 Upgrade Tip: For enhanced water clarity, consider using glass media instead of sand. Glass media can filter down to 5-15 microns and typically lasts twice as long as traditional sand.
⚙️ Valve Positions & Functions
The 6-way multiport valve provides complete control over your filtration system:
| Position | Function | When to Use |
|---|---|---|
| Filter | Normal filtration mode | Daily operation – water passes through media and returns clean to pool |
| Backwash | Reverses flow to clean media | When pressure gauge rises 0.5-1.0 bar above baseline |
| Rinse | Settles media after backwash | Always use for 30-60 seconds after backwashing |
| Waste | Bypasses filter, drains to waste | Vacuuming heavy debris, lowering water level |
| Recirculate | Bypasses filter, returns to pool | Circulating chemicals without filtering |
| Closed | Stops all water flow | Pump maintenance, winterisation |
⚠️ Important: Never operate the valve handle whilst the pump is running. Always switch off the pump before changing valve positions.
🎯 Ideal Applications
| Application | Pool Volume | Suitability |

A: The EHS760/T is suitable for pools up to approximately 175,000 litres with an 8-hour turnover, or 132,000 litres with a 6-hour turnover. For optimal water quality, we recommend sizing for 6-hour turnover where possible.
Q: How often do I need to backwash?
A: Backwash when the pressure gauge reads 0.5-1.0 bar above your clean baseline reading. This is typically every 1-2 weeks depending on pool usage and debris levels.
Q: What filter media should I use?
A: The filter is compatible with standard silica sand (175 kg), glass media, or zeolite. You’ll also need 50 kg of gravel for the base layer. Glass media offers finer filtration and longer lifespan.
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. ZeoSand typically lasts around 5 years.
Q: What pump do I need?
A: Match with a pump delivering approximately 18-22 m³/h. The pump should not exceed the filter’s maximum flow rate of 22 m³/h. Ensure your pump has adequate head pressure for your system.
Q: What is the maximum working pressure?
A: The maximum working pressure is 2.5 bar. The filter has been tested to 4 bar (20,000 cycles). Recommended operating pressure is 0.5-1.6 bar.
Q: Can this filter be used with heated pools?
A: Yes, the EHS760/T is rated for a maximum operating temperature of 50°C, making it suitable for heated pool applications.
Q: What warranty is included?
A: Please contact Parts4Tubs for full warranty terms and conditions applicable to this product.
Q: What is the weight when filled with media?
A: Empty weight is 33 kg. With 175 kg sand and 50 kg gravel, total weight when filled is approximately 258 kg. Ensure your installation base can support this weight.
