FAQs
What is a dual-flush toilet and how does it work?
A dual-flush toilet is a high-efficiency fixture that gives you two flushing options: a reduced-volume flush (about 0.8 gpf) for liquid waste and a full-volume flush (1.28 gpf or less) for solid waste. The user selects the desired flush by pressing one of two buttons or handles. Inside the tank, a specialized valve regulates how much water is released, allowing the toilet to clear waste effectively while conserving water when possible.
How much water and money can I save by upgrading to a dual-flush system in Coalmont?
Switching from an older 3.5 gpf toilet to a dual-flush model can cut toilet water use by up to 65 %. For an average household of four in Coalmont, that translates to roughly 12,000â15,000 gallons saved per year. Based on the cityâs current water-and-sewer rate (about $0.011 per gallon combined), the savings can reach $130â$170 annually, meaning most installations pay for themselves in two to four years.
Will a dual-flush toilet fit my existing bathroom plumbing and rough-in size?
Yes, in most cases. Nearly all dual-flush bowls use the standard 12-inch rough-in found in Coalmont homes. If your bathroom has an older 10- or 14-inch rough-in, we carry offset flanges and special-order bowls designed for those sizes. Waste line diameter, venting, and shut-off valve locations rarely need changes, but we inspect everything during the initial site visit to be sure. If modifications are required, weâll quote them in advance.
Do I need a permit in Coalmont to replace my old toilet with a high-efficiency dual-flush model?
The City of Coalmont treats toilet replacement as a minor plumbing alteration, so homeowners do not need to pull a separate building permit when the work is performed by a licensed plumber like us. However, state code requires that any replacement meet current low-flow standards (1.28 gpf maximum for full flush). We file the necessary work order with the city utilities department and provide you with a compliance certificate for your records.
How long does a typical dual-flush toilet installation take, and will my bathroom be out of service?
A straightforward replacement usually takes 90 minutes to two hours. That includes shutting off the water, removing the old toilet, installing a new wax ring or rubber seal, leveling and bolting the new bowl, connecting the tank, and testing both flush modes. Your bathroom is out of service only during this window, and we protect floors and nearby fixtures with drop cloths. Complex jobs (e.g., flange repair or subfloor leveling) can add an hour or two, but weâll give you a precise timeline before we start.
What maintenance is required to keep the dual-flush mechanism working reliably, and what warranty do you provide?
Maintenance is minimal: avoid bleach tablets in the tank, clean the buttons or handle monthly, and replace the seal in the flush valve about every 5â7 years (a $10 part). If you notice the toilet running, call usâmost issues are fixed in minutes. We provide a two-year labor warranty on all installations, and the manufacturers we carry (TOTO, Kohler, American Standard) back their ceramic bowls with a limited lifetime warranty and their dual-flush valves for five years.
