FAQs
What is a dual-flush toilet and how does it work?
A dual-flush toilet is designed with two separate flush options: a reduced-volume button or lever for liquid waste (usually 3–4 L) and a full-volume flush for solid waste (about 4.5–6 L). A specially engineered trapway and valve system clears the bowl efficiently with less water, giving homeowners a convenient way to cut water use without sacrificing performance.
How much water—and money—can I expect to save by upgrading to a dual-flush model?
Compared with older 11–13 L per flush toilets, a modern dual-flush unit can reduce water consumption by up to 60 %. For an average household in McDonald, that translates to roughly 50–90 kL of water saved per year, or about $90–$160 off the annual water bill, depending on usage and current SA Water rates.
Will a dual-flush toilet fit my existing plumbing and rough-in?
Most homes in McDonald have the Australian standard 140–165 mm (rough-in) waste outlet, and virtually all reputable dual-flush brands offer models that match this specification. During the in-home assessment, our licensed plumbers measure your rough-in, check the water supply position, and confirm floor or wall waste compatibility. If minor adjustments are required, we’ll quote them upfront before any work begins.
What is the typical cost to replace my current toilet with a dual-flush unit?
Prices vary by brand, style, and any plumbing modifications needed, but a standard close-coupled dual-flush suite—including supply of the toilet, fittings, labour, and disposal of the old unit—generally ranges from $550 to $880 in McDonald. Premium wall-hung or back-to-wall concealed-cistern models can run $1,200 to $2,000+. We provide fixed-price quotes so you know the total investment before work starts.
How long does installation take and will I be without a toilet?
A straightforward replacement usually takes 1.5–2.5 hours. You’ll only be without the toilet during that window; we can schedule the job at a time that minimises inconvenience. If floor repair, flange relocation, or tile work is required, the project can extend to half a day. Our team protects adjacent flooring, cleans up thoroughly, and tests the new unit before we leave.
Are there any rebates or local incentives for installing a water-efficient dual-flush toilet in McDonald?
Yes. SA Water periodically offers rebates for Water Efficiency Labelling and Standards (WELS) 4-star and 5-star toilets, which includes most dual-flush suites. As of this year, eligible homeowners can claim up to $100 per toilet when replacing an inefficient model. We supply the paperwork and provide your plumber’s certificate of compliance to streamline the application process.
