FAQs

What qualifies a toilet as “high-efficiency” (HET), and how much water can it save?

A toilet is classified as a High-Efficiency Toilet (HET) when it uses 1.28 gallons per flush (gpf) or less, compared with the federal standard of 1.6 gpf. Dual-flush HETs average even lower—about 1.1 gpf—by offering a reduced-volume flush for liquids and a full-volume flush for solids. Switching from a 3.5 gpf or older 5 gpf toilet to an HET can save 20,000–30,000 gallons of water per household each year, cutting water bills by up to 60 %.

Will a high-efficiency toilet provide the same flushing power as my old one?

Yes. Modern HETs rely on improved bowl hydraulics, precision-engineered trapways, and pressure-assist or siphon-jet technologies to move waste more effectively using less water. Most models undergo independent MaP (Maximum Performance) testing, and reputable brands achieve 800–1,000 g of waste removal—far above the 350 g minimum considered highly reliable. In short, an HET matched to your home’s water pressure delivers equal or better performance than older high-volume toilets.

Can my existing plumbing handle a high-efficiency toilet upgrade?

In the vast majority of homes, yes. HETs connect to the same 12-inch rough-in and 3-inch drain lines that standard toilets use. Because wastewater velocity remains adequate, the shorter water column does not create drainage issues in typical residential systems. For long horizontal runs or commercial retrofits, our technicians conduct a quick drain line slope and venting check to ensure optimal flow. If any adjustments are needed (rare), they are usually minor, such as adding a cleanout or verifying adequate venting.

How complicated is the replacement process and how long does it take?

A standard replacement—removing the old toilet, inspecting the flange, installing a new wax or rubber seal, setting the HET, and connecting the supply line—takes about 1.5–2 hours. Complexity increases if the flange is damaged, the rough-in differs (e.g., 10" or 14"), or flooring repairs are needed; even then, most jobs finish the same day. Our licensed plumbers arrive with drop cloths, haul away the old fixture for recycling, and leave the workspace clean.

What maintenance differences should I expect with a high-efficiency model?

Routine care is similar: occasional bowl cleaning with non-abrasive products and periodic flapper or seal replacement (every 5–7 years). Because HETs use less water, mineral buildup can appear sooner in hard-water areas; a monthly vinegar flush helps prevent this. If you choose a pressure-assist model, an internal cartridge may need replacement after 8–10 years. All parts are readily available and inexpensive. We also offer annual tune-ups that include leak checks and valve calibration.

Are rebates or incentives available for upgrading to a high-efficiency toilet?

Many utility districts, cities, and states offer rebates ranging from $50 to $200 per toilet to encourage water conservation. Some programs cover dual-flush or WaterSense-labeled HETs only, while others include installation costs. We maintain an up-to-date database of local incentives and will help you complete the paperwork, provide proof of purchase, and schedule any required inspections so you receive your rebate promptly.
