Frequently Asked Questions

Q: What is included in this dual flush cistern valve kit?

A: The kit includes both the fill valve and the drain/outlet valve — providing a complete two-button dual flush solution for your toilet cistern. Everything you need to replace your existing cistern mechanism is included in the one package.

Q: Is this dual flush toilet valve compatible with my cistern?

A: This valve is designed to be compatible with most standard toilet cisterns that use a two-button split flush system. We recommend measuring your existing cistern dimensions and checking valve thread sizes before installation to confirm compatibility.

Q: Can I install this cistern valve myself?

A: Yes! The split valve design is engineered for straightforward DIY installation in most standard cisterns. Basic plumbing knowledge and common household tools are typically all that's needed. For complex or non-standard cisterns, consulting a licensed plumber is always a good idea.

Q: How does a dual flush valve save water?

A: A dual flush system offers two flush volumes — a smaller half-flush for liquid waste and a larger full flush for solid waste. This reduces the amount of water used per flush cycle compared to a single-flush system, lowering overall household water consumption over time.
