Water Flow Regulators

• Up to 70% Water Savings at Taps, Showers etc
• Helps comply with The Code For Sustainable Homes
Can help you achieve BREEAM Wat 1 credits

  • Application
  • Taps, showers & baths etc supplied by water with a minimum pressure of approx. 1 Bar (i.e. pumped/mains water supply, or gravity fed tall buildings).

  • Function
  • Point of use regulators designed to provide constant and maximum flow rates at taps and showers etc. irrespective of changes in demand or water pressure fluctuations between 1–10 Bar.

  • Benefits
  • • Large water savings and also by reducing the amount of hot used you can achieve large energy savings
    • Even water distribution throughout the site, even at peak demand periods
    • Lower capital costs (potential savings from smaller pipework, water heating systems etc.)
    • Reduced "peak demand"
    • Ideal for retro-fit or new build projects
    • Low cost solution. Payback often within months
    • Help reduce "back splash" at basins
