💧 Pentair Tagelus 610mm Top Mount Sand Filter with 1HP Swimflo Pump

Superior filtration performance for pristine swimming conditions all season long

🏊 Product Overview

The Pentair Tagelus TAG24 paired with the Certikin Swimflo HPS101M 1HP pump creates a powerful, reliable filtration system engineered for medium to large domestic swimming pools. This proven combination delivers the performance needed for pools up to 84,000 litres whilst maintaining excellent energy efficiency.

The 24″ (610mm) Tagelus filter features Pentair’s renowned seamless one-piece fibreglass-reinforced tank construction that eliminates any possibility of leaks and provides exceptional resistance to corrosion. The special internal diffuser creates a uniform sand bed that traps more debris without restricting water flow, ensuring more effective filtration and extended run times between backwashing.

📏 Pool Sizing Guide

Sizing Principle

For effective pool sanitation, the filter system should turn over the entire pool volume in 6-8 hours. The Tagelus TAG24 has a maximum flow rate of 14 m³/hr, which determines the pool sizes this system can effectively handle.

🧹 Maintenance Guide

Routine Maintenance Schedule

Task	Frequency	Details
Check pressure gauge	Weekly	Note baseline reading when filter is clean
Backwash filter	When pressure rises 0.5-0.7 bar above baseline	Typically every 1-2 weeks during swim season
Rinse after backwash	After each backwash	30-60 seconds until sight glass clears
Inspect pump strainer basket	Weekly	Remove debris, check for damage
Check for leaks	Monthly	Inspect all unions and connections
Inspect media level	Annually	Top up sand if settled significantly
Full media replacement	Every 5-7 years	Replace sand completely

Pressure Gauge Guide

Reading	Status	Action
0.5-1.0 bar	Normal clean filter	No action needed
1.0-1.5 bar	Filter loading	Monitor – backwash soon
1.5-2.0 bar above baseline	Backwash needed	Backwash immediately
Above 2.5 bar	Potential blockage	Check system, investigate cause

Backwash Procedure

1. Turn off pump – Never operate valve with pump running
2. Set valve to BACKWASH – Rotate handle to backwash position
3. Turn on pump – Run until sight glass shows clear water (2-4 minutes)
4. Turn off pump – Stop flow before changing valve position
5. Set valve to RINSE – Rotate to rinse position
6. Turn on pump – Run for 30-60 seconds to settle media
7. Turn off pump – Stop flow
8. Set valve to FILTER – Return to normal filtration mode
9. Turn on pump – Resume normal operation

💡 Tip: The TAG24’s larger media capacity means slightly longer backwash times may be needed compared to smaller filters.

Winterisation (UK Climate)

For pools not heated during winter:

1. Drain filter tank – Open drain valve completely
2. Remove drain plug – Store in safe place
3. Backwash thoroughly – Clean media before shutdown
4. Drain pump – Remove drain plugs from pump body
5. Remove pump strainer basket – Clean and store dry
6. Disconnect unions – Allow water to drain from pipework
7. Protect from frost – Cover filter or store in frost-free location
8. Never leave water in system – Freezing causes permanent damage

🔬 Filtration Performance

Performance Metrics

Metric	Value
Flow Rate	14 m³/hr
Filter Area	0.19 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 particles, some algae
10-20 microns	Fine particles, most algae, cloudiness
5-10 microns	Very fine particles, bacteria, superior clarity

Upgrading Filtration Performance

For enhanced water clarity, consider replacing standard sand with glass media:

• Finer filtration (5-15 microns vs 20-40 microns)
• Reduced backwash frequency – saves water and chemicals
• Lower media consumption over time
• Extended media lifespan (10+ years vs 5-7 years)

🎛️ Multiport Valve Positions

The 6-position top-mounted multiport valve provides complete control:

Position	Function
FILTER	Normal filtration – water flows through media to pool
BACKWASH	Reverses flow to flush debris from media to waste
RINSE	Settles media after backwash, flows to waste
WASTE	Bypasses filter, sends water directly to drain
RECIRCULATE	Bypasses filter, returns water to pool (for chemical mixing)
CLOSED	Stops all water flow through valve

⚠️ Important: Always turn off pump before changing valve position

❓ Frequently Asked Questions

Q: What size pool will this filter system handle? A: The Tagelus TAG24 with Swimflo 1HP pump is ideal for pools up to 84,000 litres with optimal 6-hour turnover, and can handle pools up to 112,000 litres with 8-hour turnover. This makes it suitable for most medium to large residential pools.

Q: How often do I need to backwash? A: Backwash when the pressure gauge reads 0.5-0.7 bar above the clean baseline reading. This is typically every 1-2 weeks during the swimming season, though frequency varies with pool usage, bather load, and environmental debris.

Q: What filter media should I use? A: The filter requires 40kg of gravel as a support layer and 108kg of filter sand (16/30 grade, 0.4-0.8mm). Alternatively, glass media can be used for finer filtration and longer service life.

Q: How long does filter media last? A: Standard silica sand lasts 5-7 years. Glass media can last 10+ years. Replace when water clarity suffers despite proper chemical balance.

Q: Is the pump self-priming? A: Yes, the Swimflo HPS101M is fully self-priming. However, positioning the pump below water level improves priming reliability and reduces strain on the pump.

Q: What electrical supply is required? A: The system requires a 230V single-phase supply. Installation must comply with BS 7671 regulations and should include RCD protection. A qualified electrician should complete the electrical connection.

Q: Can I use this with a salt chlorinator? A: Yes, both the Tagelus filter and Swimflo pump are designed for use with salt chlorinated pools. The composite and stainless steel construction resists corrosion from salt water.

Q: What warranty is provided? A: The Tagelus filter shell has a 10-year limited warranty. The Swimflo pump has a 2-year warranty. Contact Parts4Tubs for full warranty terms and conditions.

Q: How do I winterise the system? A: Drain all water from the filter tank and pump, remove drain plugs, and store in a frost-free location or cover securely. Never leave water in the system during freezing conditions as ice expansion causes permanent damage.

Q: What flow rate does the pump deliver? A: The Swimflo 1HP delivers up to 21 m³/hr at low head pressure. At typical operating conditions (8m head), it delivers approximately 16.6 m³/hr. The filter’s maximum design flow of 14 m³/hr is the system’s limiting factor.

Q: How does this compare to the smaller 480mm system? A: The TAG24 offers 65% higher flow rate (14 vs 8.5 m³/hr) and more than double the media capacity (148kg vs 72kg), making it suitable for pools up to 112,000L compared to 68,000L for the TAG19..
