FAQs

Is this valve suitable for high-pressure systems?

Yes, it is compatible with a wide pressure range from 0.1 to 20 bar.

Will this fit a bottom-inlet cistern?

No, this specific model is designed for side-inlet configurations only.

Does this valve help save water?

Yes, its delayed-action technology saves approximately 6 liters of water per day for an average family.

What is the connection size?

This model features a standard 1/2-inch connection.

Is the valve compliant with local regulations?

Yes, the product is WRAS and KIWA Reg4 compliant.

Troubleshooting

Cistern is failing to fill

Verify that the isolation valve is fully open and ensure the float is not caught against the cistern wall.

Water continues to run after filling

Check the float height adjustment; if it is set too high, the water level will exceed the overflow limit.

Noise during the filling process

Ensure all washers are seated correctly and that there is no debris in the inlet filter screen.

Pros and Cons

Pros

  • Significantly reduces daily water consumption
  • Extremely compact for limited-space cisterns
  • Highly adjustable with a rotating head
  • Versatile high and low-pressure compatibility
  • Excellent safety compliance and certifications

Cons

  • Requires professional side-inlet plumbing configuration
  • Not suitable for bottom-inlet cistern designs
  • Installation may require basic plumbing tools

Setup, Compatibility & Care

Installation requires a standard 1/2-inch connection. Ensure the water supply is turned off completely at the isolation valve before removing the old inlet. The 180-degree rotating head allows you to align the inlet to match your current supply pipe, minimizing the need for complex pipe bending. To maintain optimal performance, periodically check the float housing to ensure it remains free of limescale buildup, especially in hard-water regions. Avoid using chemical cleaners inside the cistern that could degrade the plastic components over time.
