Frequently Asked Questions

Q: What toilet tank types is this 3-inch flush valve repair kit compatible with?

A: This kit is designed for split-type toilet tanks that use a standard 3-inch flush valve. It is compatible with most common household toilet tanks. If you are unsure, measure your existing flush valve before purchasing.

Q: How does the dual-flush button help conserve water?

A: The top-mounted double-button system gives you two flush volume options — a shorter press delivers a partial flush for liquid waste, while a full press activates a complete flush. This flexibility can significantly reduce the amount of water used per flush compared to a single-flush system.

Q: Do I need a plumber to install this toilet repair kit?

A: No. This kit is designed for straightforward DIY installation. The components fit together intuitively and no specialised tools are required. Most users can complete the installation in under 30 minutes by following the included guidelines.

Q: Is the fill valve noisy during tank refill?

A: The needle-type fill valve is engineered for stable, efficient water intake, which helps minimise noise and turbulence during the tank refill cycle compared to older ballcock-style valves.
