💧 Certikin Lacron 24″ LSR Side Mount Sand Filter with 1HP Aquaspeed Pump Combo – Complete Pool Filtration System

Superior filtration performance for medium to large residential pools

🏊 Product Overview

The Certikin Lacron 24″ LSR Side Mount Sand Filter paired with the 1HP Aquaspeed Pump delivers powerful, reliable filtration for medium to large residential swimming pools. With over 30 years of proven performance and more than a quarter of a million units installed across Britain, the Lacron Sureflow remains the UK’s most trusted sand filter brand.

This complete filtration package combines the renowned Lacron LSR side mount sand filter with Certikin’s hydraulically efficient 1HP Aquaspeed pump, providing everything you need for crystal clear pool water in larger installations. The side-mounted multiport valve configuration allows servicing of the filter interior without disturbing the connecting pipework, whilst the large 230mm clear lid provides excellent visual display of water flow—particularly useful during backwashing.

The 24″ diameter filter tank offers substantially greater capacity than smaller models, making it ideal for pools up to 87,000 litres with optimal turnover. The robust GRP (Glass Reinforced Polyester) construction and the Aquaspeed’s single-piece fibreglass pump body ensure maximum durability and long service life. Fully compatible with salt chlorinated pools.

📐 Pool Sizing Guide

Sizing Principle: The filter flow rate should turn over the entire pool volume in 6-8 hours for optimal filtration performance.

Formula:

Pool Volume (litres) = Flow Rate (m³/h) × Turnover Time (hours) × 1000

This Combination’s Capacity

📍 Filter Design Flow Rate: 14.5 m³/h

📍 Pump Flow Rate: 15 m³/h at 10m head

📍 Optimal Pool Size (6-hour turnover): Up to 87,000 litres

📍 Maximum Pool Size (8-hour turnover): Up to 116,000 litres

Pool Size Compatibility Table

Pool Type	Volume Range	Suitability
🏠 Medium in-ground	40,000 – 60,000 L	✅ Excellent – ample capacity
🏠 Large in-ground	60,000 – 87,000 L	✅ Excellent – ideal match
🏠 Very large in-ground	87,000 – 116,000 L	✅ Good – within design range
🏢 Small commercial	Up to 87,000 L	✅ Suitable – consider pea gravel layer

💡 Tip: The Lacron LSR 24″ side mount filter is ideally suited to permanent in-ground residential pools. For larger 24″+ filters used in commercial environments, adding a pea gravel layer beneath the sand is recommended to improve flow distribution and reduce bacterial growth in the filter base.

🔄 Maintenance Guide

Routine Maintenance Schedule

Task	Frequency	Details
Check pressure gauge	Weekly	Record baseline reading when clean
Backwash filter	Every 1-2 weeks	When pressure rises 0.5 bar above baseline
Rinse after backwash	After each backwash	Run for 30-60 seconds until water clears
Inspect pump basket	Weekly	Remove debris, check for damage
Check pump lid seal	Monthly	Replace if worn or cracked
Inspect filter media level	Annually	Top up if low (should be 2/3 full)
Full media replacement	Every 5-7 years	Or when water clarity declines

Pressure Gauge Guide

📊 Clean filter baseline: 0.8 – 1.0 bar (typical)

📊 Backwash required: When pressure rises 0.5 bar above baseline

📊 Maximum safe operating pressure: 2.5 bar

⚠️ Warning: If pressure exceeds 2.5 bar, stop pump immediately and investigate blockage.

Backwashing Procedure

1. Turn off pump
2. Set multiport valve to BACKWASH position
3. Turn on pump and run until sight glass shows clear water (typically 2-3 minutes)
4. Turn off pump
5. Set valve to RINSE position
6. Turn on pump for 30-60 seconds
7. Turn off pump
8. Return valve to FILTER position
9. Resume normal operation

Winterisation (UK Climate)

• Drain all water from pump, filter tank, and pipework
• Remove and store drain plugs safely
• Set multiport valve to WINTER position (between settings) to relieve pressure on spider gasket
• Cover or store pump in frost-free location if possible
• Never leave water in the system during freezing conditions—ice damage is not covered by warranty

• With pea gravel (recommended for commercial use): 100kg sand + 25kg pea gravel base layer

Signs Media Needs Replacing

• Poor water clarity despite correct chemical balance
• Short filter cycles between backwashes
• Channelling visible through clear lid
• Media visible in pool returns
• Filter more than 7 years old (sand) or 10 years (glass)

🛠️ Multiport Valve Positions & Functions

Position	Function
FILTER	Normal filtration—water flows through media and returns to pool
BACKWASH	Reverse flow to clean media—dirty water exits via waste line
RINSE	Settles media after backwash—run for 30-60 seconds
WASTE	Bypasses filter—water drains directly to waste (for lowering water level)
RECIRCULATE	Bypasses filter—water returns to pool without filtration
CLOSED	Stops all water flow—use only when pump is off
WINTER	Between positions—relieves pressure on spider gasket for storage

⚠️ Important: Never turn multiport valve handle while pump is running—this can damage the spider gasket.

❓ Frequently Asked Questions

Q: What size pool will this filter and pump combination handle? A: This combination is suitable for pools up to 87,000 litres with optimal 6-hour turnover, or up to 116,000 litres with 8-hour turnover. The filter’s design flow rate is 14.5 m³/h.

Q: How often do I need to backwash the filter? A: Backwash when the pressure gauge reads 0.5 bar above the clean baseline reading, typically every 1-2 weeks depending on pool usage and debris levels. The clear lid on top makes it easy to observe when the water runs clear during backwashing.

Q: What filter media should I use? A: The filter is compatible with silica sand (16/30 grade), glass media, or zeolite. Sand is economical and effective; glass media provides finer filtration and longer life. The media capacity is 125kg.

Q: Should I use pea gravel with this filter? A: For residential use, sand alone is sufficient. For commercial applications or heavy-use pools, adding a 25kg pea gravel base layer improves flow distribution and backwash effectiveness.

Q: How long does filter media last? A: Silica sand typically lasts 5-7 years, glass media 10+ years, and zeolite approximately 5 years. Replace when water clarity diminishes despite correct chemical balance.

Q: Is this combination suitable for saltwater pools? A: Yes, both the Lacron filter and Aquaspeed pump are fully compatible with salt chlorinated pool systems.

Q: Why choose a side mount filter over top mount? A: The side mount configuration allows you to service the filter interior and change media without disturbing the connecting pipework. The large clear lid on top also provides a visual display of water flow during operation.

Q: What warranty is included? A: The filter tank carries a 5-year warranty with 1-year warranty on components. The pump has a 2-year warranty with 1 year on mechanical seal and capacitor. Contact Parts4Tubs for full warranty terms.

Q: Can I install this myself? A: The plumbing can be undertaken by competent DIY enthusiasts, however the electrical connection must be completed by a qualified electrician. We recommend professional installation for warranty purposes.

Q: How do I winterise the system in the UK? A: Drain all water from the pump, filter, and pipework. Remove and store drain plugs. Set valve to WINTER position. Never leave water in the system during freezing conditions as ice damage is not covered by warranty.
