Keeping Your Pool Running Smoothly
Your pool plant room is the heart of your swimming pool, housing the pumps, filters, controls and pipework that keep the water clean, safe and enjoyable to use. While much of this equipment works quietly behind the scenes, regular care and expert maintenance are essential to keep everything operating efficiently.
Whether you need a complete plant room installation, equipment upgrades, routine servicing or specialist repairs, Harlequin Pools provides a comprehensive in-house service. We design, install, maintain and repair pool plant systems of all sizes, delivering practical advice, quality workmanship and complete peace of mind.
Why Invest in Your Pool Plant?
Reliable Pool Performance
Well-maintained equipment keeps your pool operating safely, efficiently and consistently throughout the year.
Improved Water Quality
Modern filtration, circulation and treatment systems help maintain cleaner, healthier water with less manual intervention.
Lower Running Costs
Efficient equipment and correctly configured systems can reduce energy consumption while extending the lifespan of your pool plant.
Expert Advice You Can Trust
We’ll recommend solutions that genuinely suit your pool and your requirements—not simply the latest technology.
New Plant Room Installations
Whether you’re relocating an existing plant room or replacing an ageing installation, we’ll design and build a system that’s efficient, reliable and built to current standards.
Our team designs the layout, supplies all equipment and carries out the complete installation, including electrical and hydraulic works. Where required, we also manufacture bespoke control panels tailored to your pool and its equipment. Every installation is fully tested, commissioned and documented, with all relevant certification completed before handover.
From complete plant room replacements to refurbishment projects, we provide a single point of contact from initial design through to completion.
Plant Room Upgrades
Upgrading individual components can significantly improve the performance, efficiency and ease of maintaining your swimming pool.
We regularly install automatic pool cleaners, UV disinfection systems and chemical dosing equipment, integrating each system seamlessly into your existing plant room. We also advise on variable speed pumps, providing honest recommendations based on how your pool operates rather than suggesting unnecessary upgrades.
Every improvement is designed to enhance reliability, simplify maintenance and help your pool perform at its best.
Servicing & Repairs
Regular inspections help identify developing issues before they become expensive repairs, keeping your pool operating efficiently. If your pool is becoming harder to maintain, water pressure has dropped or equipment is making unusual noises, our engineers can quickly diagnose the cause and recommend the right solution.
We repair everything from leaking pipework and failed pump seals to filtration systems, automatic dosing equipment and control systems. Where specialist support is required, we’ll coordinate the work while remaining your single point of contact, ensuring every repair is completed to the highest standard.
Filter Media Changes
Filter media naturally loses effectiveness over time, reducing water clarity and filtration performance. We supply and replace filter media for domestic and semi-commercial pools, selecting the correct media for your filter and pool.
Our service includes stripping down the filter vessel, inspecting internal components, replacing the media and recommissioning the system. We recommend traditional sand and gravel filtration for its proven reliability, although glass media, OC1 and activated carbon are also available. We keep records of every media change and provide replacement reminders.
