Frequently Asked Questions

Q: Will this 38mm dual flush push button fit my toilet cistern?

A: This push button is designed to fit most standard cisterns with a 38mm thread diameter. We recommend measuring the thread diameter of your existing button or cistern opening before purchasing to confirm compatibility.

Q: Is this flush button easy to install without a plumber?

A: Yes! The screw-in design makes installation straightforward for most DIYers. Simply unscrew the old button, thread in the new one, and attach the rod assembly — no specialist tools or plumbing experience required.

Q: What is the difference between a dual flush button and a single flush button?

A: A dual flush button offers two flush options — a lower-volume flush for liquid waste and a full-volume flush for solid waste. This helps conserve water compared to a single-flush system, which always uses a fixed volume of water per flush.
