FAQs
What makes an ultra-efficient dual-flush toilet different from a standard model?
Ultra-efficient dual-flush toilets use two buttons or levers: a reduced-volume flush for liquid waste (typically 0.8–1.0 gpf) and a full-volume flush for solids (1.28 gpf or less). Compared to the 1.6 gpf single-flush standard, this design can cut water use by up to 40 %, lowering utility bills and conserving Townsend’s municipal water supply.
How much water and money can I expect to save in Townsend by upgrading?
For an average family of four, switching from a 3.5 gpf pre-1994 toilet to an ultra-efficient dual-flush model can save roughly 15,000–20,000 gallons per year. At Townsend’s current water rate of about $7.10 per 1,000 gallons, that’s $105–$140 in annual savings, often paying back the upgrade cost in under three years.
Are dual-flush toilets legal and code-compliant in Townsend?
Yes. Townsend follows the 2021 International Plumbing Code and Delaware’s High-Efficiency Plumbing Fixtures Act, both of which allow and encourage dual-flush fixtures rated at 1.28 gpf or lower. All models we install carry the WaterSense label, ensuring full compliance and eligibility for any state or utility rebates.
What is involved in replacing my existing toilet with a dual-flush unit?
Our licensed plumbers first shut off and drain your old toilet, inspect the flange and supply line, and make any needed repairs. We then install a new wax (or wax-free) seal, set the dual-flush bowl, level and secure it, attach the tank, connect the supply, and test both flush modes. Typical installations take 1–2 hours with minimal disruption, and we remove and recycle the old fixture for you.
Do ultra-efficient dual-flush toilets require special maintenance?
Maintenance is similar to any modern toilet: keep the bowl clean with non-abrasive cleaners, check the fill valve screen annually, and replace the flapper or seal every 5–7 years. Because dual-flush mechanisms use button actuators and canister or tower valves instead of traditional flappers, they’re actually less prone to leaks when properly installed.
Are rebates or incentives available for dual-flush upgrades in Townsend?
Yes. The Delaware Energy & Water Efficiency Program offers a $50 rebate for every WaterSense-certified high-efficiency toilet installed in a Townsend residence. We supply the paperwork and proof of purchase, so you simply submit the form online or by mail to receive your rebate within 4–6 weeks.
