FAQs
Why should I consider upgrading to a modern water-saving toilet in Cowan?
Older toilets can use 11–12 L per flush, whereas today’s Water Efficiency Labelling and Standards (WELS) 4–5-star dual-flush models use 4.5 L for a full flush and 3 L for a half flush. In an average Cowan household this can cut toilet water use by up to 70 %, translating to hundreds of litres—and dollars—saved every quarter while reducing pressure on local water supplies.
How much water and money will I actually save?
For a family of four flushing a typical 5 times per person per day, switching from a 12 L single-flush to a 4.5/3 L dual-flush model can save around 45 L per person per day—about 65 kL per year. At Sydney Water’s current Tier-1 price (≈$2.50 / kL), that is roughly $160 in annual bill savings, not counting potential sewer usage charge reductions.
Will a low-flow or dual-flush toilet really clear the bowl as well as my old one?
Yes. Modern water-saving toilets are engineered with redesigned bowls, steeper trapways and higher-velocity siphons that compensate for the smaller flush volume. All products we supply are minimum 4-star WELS rated and independently tested for bulk removal and splash reduction, so you get equal or better performance with less water.
Are there any rebates or incentives available for Cowan residents?
Although Sydney Water discontinued its statewide toilet replacement rebate, Ku-ring-gai Council periodically offers sustainability grants that can offset up to $250 of the purchase price for 4-star WELS fixtures. We track current programs and help you complete any paperwork, including proof-of-purchase and installer certification forms.
What is involved in the installation and how long will it take?
A standard like-for-like toilet replacement usually takes 1.5–2 hours. We isolate the water, remove the old suite, inspect the pan collar and shut-off valve, adjust or replace the connector, bed the new pan with a flexible seal, level and secure it, fit the cistern, connect supply, and test both flush options. Your bathroom is left clean and fully usable the same day.
What models can you supply and what do they cost?
We carry compact back-to-wall suites, rimless hygiene bowls and care/accessible pans, all 4–5-star WELS rated from Caroma, Roca and American Standard. Supply-and-install packages start at $530 for an entry dual-flush close-coupled suite, range up to $1,250 for a premium rimless back-to-wall with soft-close seat. Every install includes old fixture disposal and a 10-year manufacturer warranty on vitreous china.
