FAQs
What is a dual-flush toilet and how does it differ from a standard single-flush model?
A dual-flush toilet has two separate flush buttons or levers, offering a low-volume flush (usually around 0.8 gal/3 L) for liquid waste and a higher-volume flush (about 1.28 gal/4.8 L) for solid waste. A traditional single-flush toilet uses the same larger volume—often 1.6 gallons or more—every time you flush. The dual-option design lets you use only the water you need, reducing overall consumption and lowering utility bills without sacrificing performance.
How much water can I expect to save by upgrading to a dual-flush toilet in Karns?
Most Karns households that switch from older 3.5-gallon single-flush toilets to WaterSense-labeled dual-flush models cut toilet water use by 50 %–70 %. For an average family of four, that translates to roughly 12,000–16,000 gallons saved per year, equating to $80–$120 in annual water-and-sewer charges—savings that usually pay for the new fixture in two to three years.
Are dual-flush toilets compatible with my existing plumbing, or will I need additional modifications?
In the vast majority of Karns homes, a dual-flush toilet can replace a standard 12-inch rough-in toilet with no pipe alterations. The existing supply line and flange ordinarily remain in place. Our plumbers will inspect the flange height, shut-off valve condition, and floor stability before installation. If your bathroom currently has an uncommon 10-inch or 14-inch rough-in, or if the flange is damaged, we may recommend an offset flange or minor repairs, but full re-piping is rarely necessary.
What is the typical cost and timeline for a dual-flush toilet replacement in the Karns area?
For most residential jobs, the total installed price ranges from $475 to $850, depending on the model you choose, flange condition, and whether we haul away the old fixture. Standard replacements take about 1.5–2 hours from arrival to final cleanup. If floor repairs or flange resets are required, plan on an extra hour and $75–$150 in materials. We provide free in-home estimates and can usually schedule installation within two business days.
Do dual-flush toilets meet local building codes and low-flow regulations in Tennessee?
Yes. Tennessee plumbing code incorporates the 1.28-gallon maximum for high-efficiency fixtures, and every WaterSense-certified dual-flush toilet we install meets or exceeds these requirements. Our licensed Karns plumbers pull permits when required and ensure flanges, vents, and shut-off valves comply with local ordinances. You’ll receive documentation of code compliance and WaterSense certification for your records.
How do I maintain and troubleshoot a dual-flush toilet after installation?
Maintenance is straightforward: 1) Clean the bowl with non-abrasive cleaners to avoid scratching the high-glaze surface; 2) Periodically check the dual-flush buttons or lever for smooth operation; 3) Inspect the tank seal and fill valve once a year—replacements cost under $25 and install in minutes. If you experience weak flushing, first make sure the water supply valve is fully open, then check that the dual-flush mechanism hasn’t got debris blocking the flush valve opening. Our installations include a one-year labor warranty, and we’re only a phone call away for service or replacement parts.
