Filtration Plant Servicing and Media Replacement
Filtration performance dictates water purity far more than surface sanitiser. We service circulating pumps, overhaul multi-port selector valves, and extract compacted silica sand or glass media to restore hydraulic throughput and micron-level mechanical filtration.
What is included
- ✓Mechanical pump seal, impeller, and basket examination
- ✓Multi-port valve spider gasket and pressure gauge replacement
- ✓Vacuum extraction of calcified silica or glass media
- ✓Internal lateral pipework inspection inside the pressure tank
- ✓Installation of high-grade activated recycled glass media
- ✓Hydraulic flow rate and system pressure testing

Why Clients Entrust Us With Their Pools
Mechanical maintenance of pumps, pressure vessels, and filtration media.
Superior Water Polishing
Fresh glass media filters down to smaller micron levels, reducing reliance on constant chemical clarifiers.
Pump Motor Protection
Clean media beds lower hydraulic head resistance, allowing pump motors to run cooler and consume less electricity.
Elimination of Channeling
Replacing calcified media removes internal water tunnels that allow dirty water to bypass filtration entirely.
The Clarion Standards Assurance
We do not leave plant rooms or pool sides until water balance tests sit within strict chemical parameters. If an agreed treatment fails to resolve the targeted issue, we return promptly to re-test, re-dose, and rectify the issue without additional labour charges. Pricing & payment

Clarion restored an indoor mosaic pool that had turned cloudy after a faulty dosing pump. Alistair attended personally, corrected the saturation index over two sessions, and rebuilt the dosing lines without fuss.
Charles M., Cobham, GBThe contrast with our previous contractor is pronounced. The technician arrives at 08:30 promptly, carries his own auxiliary vacuum equipment, and leaves a printed record of water chemistry on the counter.
Fiona H., Sevenoaks, GBSolid, dependable maintenance. They noticed our heat exchanger pressure was dropping before it caused damage to the burner assembly. Payment via electronic bank transfer is handled smoothly once the job is finished.
