FAQs
What are low-flow toilets and how do they conserve water?
Low-flow (or high-efficiency) toilets are fixtures engineered to use 1.28 gallons per flush (gpf) or less, compared with older models that consume 3.5–7 gpf. They achieve this through precision-designed bowls, gravity-assisted or pressure-assisted flushing systems, and larger trapways that remove waste with less water. In most Hixson homes, switching to a low-flow toilet can cut bathroom water use by 20–60 %, saving thousands of gallons per year.
Will a low-flow toilet perform as well as my current standard toilet?
Yes. Modern low-flow toilets are required to meet strict performance standards set by the EPA’s WaterSense program. These tests verify that the fixture clears the bowl and drain line with a single flush. Many models also incorporate dual-flush options (a reduced flush for liquids) or pressure-assisted technology, which can outperform older 3.5 gpf toilets in both waste removal and bowl cleanliness.
How much can I expect to save on my water bill in Hixson if I replace my existing toilets?
Savings vary with household size and current fixture efficiency, but a family of four upgrading from 3.5 gpf toilets to WaterSense-certified 1.28 gpf units typically saves 12,000–15,000 gallons of water per year. At Tennessee’s average water cost (around $0.005–$0.006 per gallon including sewer fees), that equates to $60–$90 in annual utility savings—often enough to pay back the new toilet in three to five years.
Do I need to change my existing plumbing or drain lines for a low-flow toilet installation?
In most cases, no. Low-flow toilets are designed to fit standard 12-inch rough-in connections and work with typical 3- or 4-inch drain lines found in Hixson homes. Our licensed plumbers inspect the flange, supply line, and shut-off valve to be sure they’re in good condition, but rarely does pipe re-routing or upsizing become necessary. If you have an older cast-iron stack or a history of clogs, we can camera-scope the line first.
Are there rebates or local incentives for installing WaterSense-certified toilets?
Yes. Tennessee American Water and some regional utility districts periodically offer bill credits or mail-in rebates (usually $40–$100 per fixture) for WaterSense toilets. In addition, the City of Chattanooga Green Rebate Program sometimes includes high-efficiency fixtures for homeowners and small businesses in Hixson. Our office keeps current forms on hand and will help you complete the paperwork to maximize your savings.
What services do you provide during a low-flow toilet replacement, and how long does it take?
Our standard replacement package includes: (1) removal and eco-friendly disposal/recycling of the old toilet, (2) inspection of the closet flange and wax ring, (3) installation of a WaterSense-certified low-flow toilet you select, (4) new supply line and shut-off valve as needed, (5) leak and flush performance testing, and (6) haul-away of all packaging. A single fixture swap generally takes 1–1.5 hours, while multiple bathrooms can be completed in half a day. All work is backed by our one-year labor warranty and the manufacturer’s parts warranty.
