Dual-Flush Toilets: Are They Worth It in Boulder?

How dual flush works

A dual-flush toilet has two buttons: one for a light flush and one for a full flush. The light flush uses roughly half the water of a standard flush, which adds up fast in a busy household.

The savings

Toilets are the biggest water user in most homes. In Boulder County, a dual-flush unit can cut toilet water use noticeably over a year, especially in a family bathroom that gets heavy use.

The tradeoffs

The lighter flush sometimes needs a second push for solids, and some early models had more mechanical parts to fail. Newer designs are far better than the first generation.

Installation

Replacing a toilet with a dual-flush model is the same job as any toilet swap — new wax ring, proper seating, and a level flange. freezing winters and hard water are both common, and older homes often have aging supply lines A pro can do it in about an hour.
