FAQs

What is the warranty on this cistern?

The Wirquin Duo Compact is backed by a 10-year manufacturer guarantee.

Can this be installed in a standard wall?

This unit is designed primarily for furniture or in-wall carcass installations. It is not intended for stand-alone wall-hung mounting frames.

Does it come with the flush button?

Yes, the product includes a chrome dual-flush button as standard.

Is it suitable for hard water areas?

Yes, but we recommend periodic maintenance to prevent limescale buildup on the inlet and flush valves.

What are the exact dimensions?

The unit measures 336mm in height, 320mm in width, and 140mm in depth.

Troubleshooting

Continuous water flow into the pan

Check the KAYLA flush valve seal for debris or mineral buildup and ensure the overflow level is correctly adjusted.

Slow cistern refill

Inspect the JOLLYFILL AIR inlet valve for blockage and confirm that the isolation valve is fully open.

Flush button feels loose

Tighten the retaining nut behind the furniture fascia and ensure the cable or rod mechanism is correctly seated.

Setup, Compatibility & Care

Before starting installation, ensure your furniture unit is reinforced to support the weight of the cistern and water.

Positioning: Align the cistern within the 400mm unit, ensuring the bottom-entry inlet is accessible for your water supply line.
Connection: Use the provided fittings to secure the flush pipe to the pan, checking for watertight seals at all junctions.
Adjustment: Calibrate the KAYLA valve flush volume based on your specific WC pan requirements to ensure optimal clearing during use.
Care: Clean the chrome flush button with a soft, non-abrasive cloth. Do not use harsh chemicals, as they can degrade the finish. Periodically check the valve seals for any signs of mineral buildup if located in a hard water area.
