FAQs
What is considered a low-flow toilet and how much water can it save in a Sewanee home?
A low-flow (high-efficiency) toilet is defined by U.S. EPA WaterSense guidelines as using 1.28 gallons per flush (gpf) or less, compared with the older 3.5–7 gpf models still found in many Sewanee homes. Switching to a WaterSense-labeled fixture can reduce toilet water use by roughly 60 %, saving 13,000–16,000 gallons per household every year—an especially important benefit for properties on well systems or septic tanks common on the Mountain.
Will a low-flow toilet have enough flushing power for Sewanee’s older sewer lines and septic systems?
Yes. Modern low-flow toilets rely on redesigned bowls, smooth trapways, and pressurized or gravity-assisted siphon action rather than water volume alone. Models certified by WaterSense and tested by the Maximum Performance (MaP) program can remove 800–1,000 grams of waste per flush—equal to or better than legacy 3.5 gpf units. Our plumbers help you pick models proven to perform well with both the gravity sewers downtown and the numerous private septic systems on the Domain.
Can my existing rough-in and flange be reused, or will I need additional plumbing work when I replace my toilet?
Most Sewanee bathrooms have a standard 12-inch rough-in from finished wall to flange bolts, which is compatible with the vast majority of low-flow toilets. If your home has a 10- or 14-inch rough-in, we can order specialty bowls or install an offset flange adapter. We always inspect flange condition, supply stop, and closet bend before installation; if we find corrosion or wax-ring leaks, we can repair or replace those components during the same visit to ensure a watertight, code-compliant fit.
How long does a low-flow toilet installation take and will I be without water?
A single toilet replacement typically takes 1.5–2 hours. Water is shut off only at the fixture’s supply stop, so the rest of your home’s plumbing remains in service. If we must rebuild a damaged flange or replace a shut-off valve, add 30–45 minutes. We protect flooring, haul away the old fixture for recycling or disposal, and test flush repeatedly before we leave.
Are rebates or incentives available for upgrading to a low-flow toilet in Sewanee or Franklin County?
While Sewanee Utilities currently does not offer a standing rebate, Tennessee Valley Authority (TVA) energy-water efficiency programs occasionally run seasonal incentives. Franklin County’s solid-waste department also hosts annual water-smart events where manufacturers give coupon vouchers. We monitor all active programs and can provide the latest forms or help you document model numbers, purchase dates, and WaterSense certification required to claim up to $50 per fixture when funding is available.
What maintenance does a high-efficiency toilet require after installation?
Maintenance is minimal: • Use a mild, non-abrasive cleaner to protect the bowl’s glazed surface that helps waste slide off with less water. • Inspect the flapper or seal every 2–3 years; inexpensive replacement parts keep the tank leak-free. • Avoid drop-in tank tablets containing bleach—they degrade rubber seals faster in low-volume tanks. • If you are on well water with high mineral content, periodically clean the rim holes with white vinegar to prevent scale buildup that could weaken the flush. Following these simple steps will keep your new low-flow toilet running efficiently for 20–25 years.
