Protecting you


How does the Platin Garden Comfort System work?

Rainwater is collected from the roof of the property and fed into the underground tank via the downpipes. On entry to the underground tank, the water passes through a filter to prevent any debris from going into the tank.

There is a pressure-sensitive pump located in the underground tank. When a valve or tap is opened, water will be pumped under pressure until the valve is closed, allowing the system to repressurise and turning the power off to the pump.

Why choose the Platin Garden Comfort Package?

  • Gravel Backfill Innovation: Unlike traditional systems that require costly concrete, our system utilises gravel backfill. This not only makes installation simpler but also saves you an impressive £60 per cubic metre.
  • Versatile Placement with Vehicle Loading Lid: Space constraints? No problem. The vehicle loading lid allows the system to be installed under your driveway, offering flexibility without compromising on functionality.
  • Sustainable Materials for a Greener Future: Committed to the environment, our system features an underground tank made entirely from 100% recycled plastic, aligning with your eco-conscious values.
  • European Market Leader Quality: When you choose Platin, you’re opting for a product trusted and favoured across Europe for its reliability and effectiveness in rainwater harvesting.
  • Seamless UK Delivery and Installation: We ensure a smooth journey from purchase to installation with free UK mainland delivery.
  • Smart Water Management: The included automatic submersible pump is engineered for efficiency. With features like automatic restart and dry-run protection, it intelligently manages water usage, ensuring longevity and reducing maintenance.
