Gotta Go Low-Flow?

Denver's water conservation managers are pressing Colorado lawmakers to outlaw the sale of toilets that use more than 1.28 gallons per flush, the Denver Post reported Tuesday.

The old porcelain fixtures use an average volume of 3.14 gallons per flush -- but they usually don't have to be flushed twice.

According to the newspaper, the plan pitched by water conservationists would not force homeowners to replace their older model toilets, but it would bar manufacturers from selling anything other than low-flow models.

A plumber told the newspaper that Denver's sewer system is designed for a higher volume of water than that produced by low-flow toilets. "What happens is, the solids get left behind in the sewers," he said. "If it's not broken, don't fix it."
