The need to conserve water has pushed utility companies everywhere to look for every means possible to reduce the amount of water used by their customers. Since toilets account for a major amount of the water used year round, many of the municipal programs and new laws have focused on how to make a toilet flush with less water.
Typically, low-flow toilets use 1.2 gallons of water per flush compared with about 3.5 gallons of water used by a standard toilet. Low-flow shower heads use about 2½ gallons of water per minute compared to between four and five gallons per minute used by conventional heads. Low-flow faucet aerators can cut the water usage of faucets by as much as 40% from 4 gallons per minute to 2½.
Different types of low-flow toilets use various technologies aimed at making the toilet more functional. Some toilets have large drain passages, redesigned bowls and tanks for easier wash down. Others supplement the gravity system with water supply line pressure, compressed air, or a vacuum pump. Let an Allstate Plumbing Professional advice you of the options available to you.
Old conventional faucets don't compensate for changes in inlet pressure, so the greater the water pressure, the more water you use. New technology compensates for pressure and provides the same flow regardless of pressure. Aerators are also available that allow water to be turned off at the aerator itself. Showerheads use similar aerator technology and multiple flow settings to save water. Let an Allstate Plumbing Professional advice you on these types of toilets and fixtures.
