FAQs
1. What makes a toilet “high-efficiency,” and how much water will I save in Jonesborough?
A high-efficiency toilet (HET) is defined by the EPA WaterSense program as a model that uses 1.28 gallons per flush (gpf) or less—at least 20 % below the federal 1.6 gpf standard. If your current toilet was installed before 1994, it probably uses 3.5–5.0 gpf. Replacing a single old toilet with an HET can save an average Jonesborough household 4,000–5,000 gallons of water per year, or roughly $40–$60 on annual water and sewer charges, depending on your exact usage and the town’s tiered rates.
2. Will a high-efficiency toilet clog more easily or require double flushing?
No. Modern HETs are engineered with larger, fully-glazed trapways and optimized bowl geometry that create a stronger siphon action than many older 3.5 gpf models. Independent MaP (Maximum Performance) testing rates most WaterSense-labeled toilets at 600–1,000 grams of solid waste removal—well above the 350-gram benchmark for reliable single-flush performance. Choosing a reputable brand and the right bowl height/rough-in size for your home virtually eliminates the need for double flushing or frequent plunging.
3. What is involved in replacing my existing toilet with a high-efficiency model?
Our licensed plumbers begin by shutting off the local angle stop, draining the old tank and bowl, and removing the fixture. We inspect the closet flange for cracks or corrosion, replace or repair it if necessary, and install a new wax ring or wax-free seal. The new HET is then set, leveled, and secured with brass bolts. We attach a stainless-steel supply line, test for leaks, adjust the fill valve, and haul away the old toilet for recycling or disposal. The entire process typically takes 1½–2 hours per toilet, and your home’s main water supply is interrupted for only 10–15 minutes.
4. Are rebates or incentives available for high-efficiency toilets in the Jonesborough area?
Yes. The Tennessee Valley Authority’s EnergyRight program, in partnership with several local utilities, periodically offers $50–$75 instant rebates on WaterSense-labeled toilets. Jonesborough Water Department has also provided $25 bill credits for qualifying replacements in the past. Incentives change each fiscal year, so we’ll check current funding and submit all required paperwork on your behalf to make sure you receive any available rebates.
5. How much does a typical high-efficiency toilet replacement cost, and are permits required?
Most projects fall between $450 and $750 per toilet, including a WaterSense-certified elongated-bowl fixture, new supply line, wax ring, disposal, labor, and a one-year workmanship warranty. Final price depends on the model you select, any flange repairs, and bathroom access. Jonesborough does not require a separate permit for like-for-like toilet swaps inside an existing residence, but if we must modify drain lines or relocate the flange, we’ll pull a Washington County plumbing permit and include the fee in your estimate.
6. What happens to my old toilet after it’s removed?
We divert as much material from the landfill as possible. Porcelain bowls and tanks are broken down and delivered to a regional aggregate recycler, where they are crushed into road-bed and concrete fill. Metal parts (handle, bolts, supply tube) are separated for scrap recycling, and plastic or rubber components are sent to an authorized waste-to-energy facility. You receive a recycling certificate upon request, which can be useful for rebate documentation or LEED credits.
