All HET Up

Replace your gravity flush toilet with a high-efficiency model.

The newest generation of high-efficiency toilets (HETs) are 20 percent more efficient than current federal standards. HETs not only take water efficiency to higher levels, they are frequently capable of flushing more waste. HETs are currently offered by all major fixture manufacturers.

There is very little correlation between the amount of water flushed and the effectiveness of a toilet. In testing, some 3.5 gallon-per-flush toilets cannot consistently flush 250 grams of waste, while some 1.1 gallon toilets reliably flush a full 1,000 grams.

At a minimum, a toilet should be able to reliably flush at least 250 grams of solid waste and 24 sheets of toilet paper. The standard maximum performance rating tests a toilet’s flushing ability up to 1,000 grams.

HET’s can be dual-flush, pressure-assisted, or gravity flush. Each technology has pros and cons.

Dual-Flush HETs

These toilets have two-flush controls: one for liquid waste and the other for solids. When used properly, the overall average flush volume is typically around 1.28 gallons per flush (GPF). A variety of quality manufacturers make dual-flush toilets, some meeting the 1,000 gram test maximum. Some dual-flush toilets are lever operated, requiring the user to raise the lever for a small flush and depress the lever for a full flush. Others have two distinct buttons to select the flush. With the lever style dual-flush toilets, there is a possibility that users will not be conscientious enough to lift the lever when a small flush will suffice, thus resulting in higher than expected water use. The button style design requires a conscious decision.

Pressure-Assisted HETs

These toilets employ a closed vessel inside the tank. When pressurized water enters the vessel, air is compressed at the top. When the water is released, the air expands rapidly, creating a high-velocity jet of water that pushes the waste through the trap. Eight major manufacturers make pressure-assisted HETs that flush with just 1.1 gallons and are capable of consistently disposing of 500 to 1,000 grams in a single flush. Although pressurized units have become quieter, some people object to the brief, but noisy flush. A benefit of pressurized units is that they are flapperless.

Gravity Flush HETs

The new generation of gravity flush high-efficiency toilets typically have enlarged flappers and waste trapways. Through computer modeling and extensive testing, engineers have developed models with superior siphoning action to help pull the waste through the bowl. Gravity flush HETs are available that are capable of flushing up to 1,000 grams of solid waste. Gravity flush HETs use flappers and many of the flappers are proprietary, which may make it difficult to find replacements at your Tacoma neighborhood hardware store.

regardless of which type of toilet you ultimately decide on, your Tacoma plumber can easily handle the plumbing installation.

Hot Water | Low Water Supply

Seattle Water Heaters

Storage water heaters are by far the most common type of water heater in the U.S. today. Ranging in size from 20 to 80 gallons (or larger) and fueled by electricity, natural gas, propane, or oil, storage water heaters work by heating up water in an insulated tank. When you turn on the hot water tap, hot water is pulled out of the top of the water heater and cold water flows into the bottom to replace it. Because heat is lost through the walls of the storage tank (this is called standby heat loss), energy is consumed even when no hot water is being used. New energy-efficient storage water heaters contain higher levels of insulation around the tank, substantially reducing standby heat loss.
