FAQs
What qualifies as a high-efficiency toilet (HET) and how much water can I expect to save?
A high-efficiency toilet is defined by the EPA’s WaterSense program as any model that uses 1.28 gallons per flush (gpf) or less while still meeting strict performance tests. Standard older toilets often use 3.5–5 gpf, so upgrading to an HET can cut toilet water use by as much as 60 %, translating to roughly 13,000–16,000 gallons saved per household each year.
Are high-efficiency toilets powerful enough to prevent clogs?
Yes. Modern HETs rely on advanced bowl design, larger fully-glazed trapways, and precise flush valve engineering rather than excess water volume. Most WaterSense-labeled units must pass rigorous MaP (Maximum Performance) testing, clearing at least 350 g of waste in a single flush—often outperforming older 3.5 gpf models. Choosing a reputable brand and professional installation further minimizes the risk of clogs.
How long does it take your Decherd plumbing team to replace my existing toilet with a high-efficiency model?
A typical remove-and-replace job takes two to three hours, including water shutoff, draining, removal of the old toilet, flange inspection or repair, wax seal replacement, installation of the new unit, and leak testing. If we discover subfloor damage, outdated supply valves, or the need for a flange spacer to meet current code, additional time may be required, but most upgrades are completed within a single visit.
Will a high-efficiency toilet really lower my water bill enough to justify the cost?
In the Decherd area, water rates average around $0.007–$0.009 per gallon. With annual savings of up to 16,000 gallons, households can expect $110–$140 in yearly utility savings. Because quality HETs start around $300–$400 installed, payback often occurs in 2-4 years. Factor in possible Tennessee Valley Authority or local utility rebates (often $50 or more) and the return on investment is even faster.
Are there any rebates or incentives available in Decherd for installing WaterSense toilets?
Yes. TUA (Tullahoma Utilities Authority) and some regional water districts periodically offer $40–$75 rebates for WaterSense models replacing units manufactured before 1994. Our office keeps current forms on hand, assists with serial number verification, and submits the paperwork for you so you don’t miss out on available savings.
Do high-efficiency toilets require special maintenance or parts compared to standard toilets?
Routine care—periodic bowl cleaning with non-abrasive cleaners, ensuring the flapper is free of mineral buildup, and checking supply line connections—remains identical. Replacement parts like flappers or fill valves are widely available at local home centers, though you should match the part number to maintain WaterSense performance. Because the flush valve openings are often larger (3" instead of 2"), keeping OEM parts on hand can help preserve warranty and efficiency.
