Point of entry barrier

The Pentair technology provides effective and low-maintenance point of entry barriers, ensuring that high-quality and absolutely contaminant-free drinking water comes out of every tap in the building.




  • Securing water safety and quality throughout a building
  • Peace of mind for owners of public buildings and homeowners
  • Effective barrier against bacteria and other contaminants
  • Infection control and protection of the vulnerable against waterborne diseases
  • Prevention of Legionnaires’ disease (when applied in new plumbing systems)

    application areas

    Point of entry barriers are typically installed just behind the water meter, at the point where the water mains enters the building. UF technology provides an effective barrier against all kinds of contaminants, and peace of mind for users who have reason to be concerned about the quality of their mains water. 

    Absolute certainty about the water that will be part of your products also depends on the integrity and cleanliness of the plumbing behind the point of entry barrier.

    pentair solutions

    Pentair’s point of entry barriers use state-of-the-art ultrafiltration (UF) modules, the same as those used in the world’s most advanced water purification plants. The Gatekeeper provides an effective barrier at the point where the mains water enters the building. It retains all sediment, turbidity, and microorganisms, including bacteria, cysts, and viruses, while allowing vital minerals to pass. The proven Pentair technology delivers 100 percent certainty about safe product water of the required quality.

    Pentair Advanced Filtration helps OEMs, engineering consulting firms and EPC contractors with tailor-made solutions for their water treatment challenges. 

    Safeguarding the consistent quality of product water does not mean that this quality has to be reached at every tap. With our skid-based X-Line or vertical dead-end filtration solutions, you introduce a new point of entry barrier exactly where it is needed. Our experts can help you find the most effective and cost-efficient solution.
