The Wirquin Jollyfill Air Inlet Valve is a high-performance solution designed for homeowners and plumbing professionals seeking a reliable, water-efficient upgrade for their toilet cisterns. Its primary benefit is a sophisticated delayed-action mechanism that significantly reduces water waste, though users should note that the installation process requires basic plumbing competency and access to the cistern's internal assembly.

Yes, it is rated to operate efficiently starting at 0.1 bar.
The delayed-action mechanism is estimated to save approximately 6 liters per day for an average family.
Yes, the product is fully WRAS and KIWA Reg4 compliant.
Adjust the height of the float mechanism to ensure the water shuts off at the appropriate fill line.

Verify that the inlet supply tap is fully open and check the filter screen at the valve inlet for blockages.
Installation requires shutting off the water supply to the cistern and draining it completely before removing the old valve. The Jollyfill is a 1/2-inch connection model, making it compatible with the vast majority of standard toilet supply lines. Ensure all seals are seated correctly to prevent drips. For maintenance, it is recommended to periodically inspect the valve for sediment buildup, particularly in hard-water areas, and wipe the diaphragm area with a damp cloth if flow rates diminish over time.
