HET (High Efficiency Technology) Toilets

Today’s toilets are designed to use 1.6 gpf (gallons per flush). Unfortunately when a toilet starts to leak or is repaired the toilet starts to use more water than required. A toilet’s flush is engineered to evacuate water as quickly as possible from the bowl. This is accomplished by getting the water from the tank to the bowl and then from the bowl to the waste as quickly as possible. HET Toilets are designed to only use 1.28 gpf. These toilets cannot use more water than they are designed.

Dual Flush Technology (DFT) Toilets

Dual Flush toilets use a special flush valve in the tank of the toilet, which allows the user to select the necessary amount of water needed to evacuate the waste in the bowl. A user can select to flush either .8 gpf or 1.28 gpf. These types of toilets can save on average of 5000 gallons annually.

Front Load Washers

A typical top load washing machine will use between 30 to 50 gallons per load. A front load machine will use between 10.5 to 18 gallons per load.


Standard aerators use 2.2 to 3 gpm (gallons per minute). Replace standard aerators with aerators that use between 1 gpm and 1.5 gpm. The difference of a 2.5 gpm aerator and a 1.5 gpm aerator is 16 seconds on a 1 gallon pot.

Shower Heads

A standard shower head uses 2.5 gpm. Some shower heads are not rated and use as much as 5 gpm. Replacing a shower head with a new aerated stream shower head can reduce your usage by as much as 30%. These heads are available from manufacturers such as MOEN, DELTA and NIAGARA. These have been evaluated by PST employees to reduce water and energy consumption without changing your lifestyle.

TWH (Tankless Water Heater)

The concept of tankless water heaters has been in use for decades. This technology has been perfected and is perfectly safe. These units are so safe that they have even been installed within a bathroom. These TWH’s heat water only when they sense that a hot water faucet has been opened. As long as there is a heat source (gas or electric) then the unit will provide hot water. Tankless units will normally give you an ROI (return on investment) in 2 to 3 years.


Typical faucets today use 2.5 gpm. A new faucet which is WaterSense rated uses only 1.5 gpm or less. A steady stream of water can be maintained with as little as 1 gpm.

Approximately 97% of the water on the planet is salt water. Of the remaining 3% – only 1% is readily available for consumption.
