FAQs
What is a dual-flush toilet and how does it save water?
A dual-flush toilet is designed with two separate flush options: a low-volume button or lever (about 0.8–1.1 gallons per flush) for liquid waste, and a full-volume option (about 1.28–1.6 gallons) for solid waste. By letting you choose the appropriate flush each time, a dual-flush toilet can cut typical household toilet water use by 40–60 %, lowering both your water bill and Harriman’s overall municipal water demand.
How much can I expect to save in water and utility costs by upgrading to a dual-flush model in Harriman?
Savings vary with household size and current fixture efficiency, but the average Harriman household that replaces a 3.5-gpf (gallons per flush) toilet with a WaterSense-certified dual-flush unit typically saves 4,000–6,000 gallons of water per person each year. At the city’s average water rate of roughly $0.007 per gallon, that equates to $28–$42 in annual savings for a family of four—and even more as water rates climb over time.
Will a dual-flush toilet fit my existing plumbing and bathroom layout?
In most cases, yes. Modern dual-flush toilets use the same 12-inch rough-in and standard flange connection found in the majority of Harriman homes. If your current toilet is a specialty rough-in (10" or 14") or has a unique footprint, our technicians will measure during the initial visit and recommend either an offset flange or a model with the correct footprint to avoid floor repairs. We also check water supply line height and shut-off valve condition to ensure seamless installation.
What does the installation process involve and how long does it take?
A standard replacement generally takes 1.5–2 hours. We: 1) shut off and drain the old toilet; 2) remove and properly recycle or dispose of it; 3) inspect and, if needed, replace the wax ring, flange bolts, or flange itself; 4) set and level the new dual-flush bowl; 5) attach the tank, supply line, and seat; 6) test both flush modes for leaks and proper water level; and 7) haul away debris. Because we’re local to Harriman, same-day service is often available and permitting is straightforward under current city plumbing codes.
Do dual-flush toilets need special maintenance or repairs compared with single-flush models?
Maintenance is minimal. The main difference is the dual-flush valve mechanism, which uses a canister or tower seal instead of the traditional flapper. These seals can last 5–7 years and cost less than $15 to replace. Periodic cleaning of the rim holes and valve seat prevents mineral buildup, especially in Harriman’s moderately hard water. Our installations include a one-year labor warranty and the manufacturer’s limited lifetime warranty on vitreous china.
Are there local rebates or incentives for installing eco-friendly toilets in Harriman?
Yes. The Tennessee Valley Authority (TVA) and many local utilities, including the Harriman Utility Board, periodically offer $25–$50 bill credits for replacing 1.6-gpf or higher toilets with WaterSense-certified models. We keep track of active programs and provide the necessary documentation—such as proof of purchase, WaterSense certification number, and disposal receipt—so you can claim any available rebates. Additionally, installing a high-efficiency fixture may help in achieving LEED or ENERGY STAR points for property owners pursuing green building certifications.
