According to EPA WaterSense, showering uses almost 1/5th of all water used in your home.

The standard showerhead uses 2.5 gallons per minute. By upgrading to a WaterSense labeled showerhead that uses no more than 2.0 gallons per minute, your family will save thousands of gallons a year. Using a 5-minute shower timer will save even more.

Faucet Aerators

Bathroom and kitchen aerators are screens that cover the faucet opening where water comes out. Faucet aerators can use 2.5 gallons per minute (GPM) or as little as 0.5 GPM.

Upgrading your faucets can save 1.2 gallons per person per day, saving thousands of gallons per year while maintaining the same performance. According to WaterSense, an average family can save $250 in water and electricity costs over a faucet’s lifetime by upgrading an old, inefficient aerator.

Toilet Flappers

Leaking toilets will waste thousands of gallons, potentially causing a drastic spike in your regular monthly bill. Leaking toilets may be silent until you open your water bill. We offer toilet flappers for free that can help resolve some types of toilet leaks.

  • What to measure before you chose an efficient toilet
  • The criteria to look for when upgrading your toilet
  • How to properly dispose of your old toilet.

Why should you consider upgrading to a high-efficiency toilet?

Toilets are by far the main source of water use in the home, accounting for nearly 30% of an average home’s indoor water use. WaterSense labeled toilets are independently certified to meet rigorous criteria for both performance and efficiency. 

What do I need to know before I purchase an efficient toilet?

Review the 15 important tips for upgrading your toilets (PDF). Commercial facilities will have additional considerations.

What are the most efficient toilets on the market?

Premium high-efficiency toilets (HETs) flush effectively with 1.1 gallons per flush or less and can be found at select retailers [XLSX], as well as other retailers since this list was created, and online. 

What do I look for when buying a new toilet?

The WaterSense label identifies water-efficient products that have been independently certified to meet WaterSense criteria for efficiency and performance. 

Do high-efficiency toilets require double-flushing?

High-efficiency toilets flush just as well or better than conventional toilets. To find the most efficient toilets, search on the MaP Testing website by selecting “MaP PREMIUM Rated” toilets in the Criteria/Ratings search filters. You can further search and filter based on other features you may need. 

Maximum Performance provides additional resources and assistance to help you enter the criteria and features that YOU are looking for in a new toilet before going to the store.

How and where can I dispose of my old toilet?

Find a local disposal site that accepts old toilets for recycling or disposal. Call ahead to confirm hours and disposal fees. 

Water Heater Information

According to EnergyStar, water heating is the second largest energy use in the home. Choosing an efficient water heating system can reduce energy consumption as well as impact your indoor water use by cutting down on the time you wait for hot water to reach your faucets and showers. Whether building a new home or business; or retrofitting your property, you may want to consider upgrading from a standard electric storage tank water heating system to save water, energy, and money.

Energy Saver 101 Water Heater Infographic

What is a heat pump water heater (HPWH)?

HPWHs work by extracting heat from the air surrounding the unit, increasing heat further with compression, delivering the heat to the water and exhausting the remaining cool air back out to the area surrounding the unit. HPWHs can use less than half the energy that standard electric heaters do.

What is a tankless water heater?

A tankless water heater provides on demand hot water without the use of a storage tank. Cold water is sent to the heating unit and is released as hot water through your faucet. Tankless water heaters can be heated with natural gas or with an electric coil. Since there is no need to heat an entire water tank, they can deliver a continuous supply of hot water when needed.

What is a Point of Use (POU) Water Heater?

POU water heaters work to reduce heat loss that generally occurs in a centralized water heating system. POU devices are installed at a distance from the central water heater, near a fixture or appliance where additional heat is needed. They are usually small enough to fit in a cabinet or closet and provide a source of hot water close to the distant fixtures, creating a decentralized heating system. POUs can be beneficial for additions with remote bathrooms, or hot tubs.

What is a hot water recirculating system?

A hot water recirculating system delivers hot water on demand to reduce wait time and waste while the water running from your faucet or shower is being heated. A recirculating pump sends cold water that is in the hot water line back to the water heater, instead of allowing it to run through the faucet and down the drain. At the same time, the system fills the hot water line with hot water from the heater. When hot water reaches the system, the zone valve closes, and the pump shuts off automatically. Demand hot water recirculation systems can be activated by a thermostat, timer, switch, or run continuously. In switch systems, the user manually recirculates the water before use to ensure the lowest amount of energy and water waste. In a continuous system, the recirculating device is constantly pumping, always ensuring hot water, but also using significant energy. Pumps are typically installed at the water fixture located farthest from the water heater to allow for full recirculation in the system.

How do I determine which hot water system is best for my property?

Learn more at Energy Star and the Department of Energy. The Energy Saver 101: Water Heating infographic shows a visual comparison of costs and benefits to assist you in choosing your efficient water heating system.

Does Valley Water offer a rebate for water heating systems?

No. However hot water recirculating systems can be installed for a relatively low cost of $200-300. Read Valley Water’s Hot Water Recirculation Pilot Study to learn about the potential water savings associated with these systems.

The initial cost of installing a tankless water heater or heat pump water heater is higher than a traditional water heater. However, in the long run, generating hot water on demand can save water, energy, and money. You may be able to receive a federal tax credit for installing an Energy Star certified water heating system. Visit Energy Star Rebate Finder to see if you qualify.
