Plumbing upgrades are an effective way to conserve water and contribute to environmental sustainability while saving money.

6 Upgrades That Will Help You Conserve Water

Low-Flow Showerheads

Low-flow showerheads reduce the water used during your shower to around 2 gallons or less. Compare this to a traditional showerhead, which can use up to 5 gallons. Low-flow showerheads aerate the water flow, creating a misty spray that provides a satisfying shower experience while using significantly less water.

Low-flow showerheads typically cost around $30 to $40 (CAD 41 to CAD 55), although cheaper models are available. Consequently, they’re an affordable and easy way to conserve water.

Energy Efficient Toilets

Toilets are one of the biggest water consumers in your home, accounting for approximately 27% of your household's water usage. Replacing an older, inefficient toilet with a low-flow or dual-flush model can save thousands of gallons of water annually. Low-flow toilets use 1.3 gallons or less per flush, while dual-flush toilets let you choose between a restricted flush of around 0.8 gallons for liquid waste and an unrestricted flush of 1.6 gallons for solid waste.

The cost for materials and installation of a low-flow energy-efficient toilet is between $423 and $496 (CAD 579 and CAD 678). A dual-flush toilet typically costs between $513 and $586 (CAD 702 and CAD 801) for parts and labor.

Water-Saving Faucet Aerators

Faucet aerators are small, inexpensive devices easily installed on your kitchen and bathroom faucets. They mix air into the water stream, creating a steady, non-splashing flow while reducing water consumption. Standard faucets can use up to 2 gallons of water per minute. According to the U.S. Environmental Protection Agency, a WaterSense faucet aerator can reduce the water flow by up to 30%, helping conserve significant amounts of water over the year. You can pick up a faucet aerator for only a few dollars, making this handy little device a cost-effective way to conserve water when brushing your teeth, washing your hands or doing dishes.

Tankless Water Heaters

Traditional tank-style water heaters constantly heat and store water, leading to significant energy and water waste. Tankless water heaters work on demand, providing hot water only when needed. This saves energy and reduces water waste while waiting for hot water to reach the faucet or shower. The average cost of parts and labor is between $1,400 and $5,600 (CAD 1,914 and CAD 7,655), depending on the size and type of appliance, according to HomeGuide.

Although the initial outlay is high, a tankless water heater is typically 24% to 34% more efficient than a conventional one, resulting in significant savings annually. Additionally, in the United States, you may be able to claim a 30% tax credit on the project cost of up to $600 for an Energy Star tankless gas water heater.

Leak Detection and Repair

Even small leaks in your plumbing system can waste hundreds or even thousands of gallons of water annually. Inspect your home for signs of leaks, such as dripping faucets, running toilets or moisture around pipes and fixtures. Fixing leaks promptly can save money on your water bill and prevent further damage to your home. If you're unsure how to detect or repair leaks, hire a professional plumber to inspect and make necessary repairs.

Expect to pay between $125 and $350 (CAD 171 and CAD 479) for simple inspections and repairs. The cost range for more extensive repairs is typically between $500 and $800 (CAD 684 and CAD 1,094).

Water Recirculation Systems

A water recirculation system, also known as a hot water circulation loop or a hot water recirculating system, provides instant hot water at every faucet or shower in your home. Using a dedicated loop of pipes, it circulates hot water from the water heater throughout the plumbing system. This eliminates the need to let the water run while waiting for it to heat up, saving both water and energy.

The Spruce says recirculation systems can cost anywhere from $200 to $400 (CAD 274 and CAD 547), depending on your home's size and the complexity of the installation.

Reducing Water Use Helps the Planet — and Your Wallet

If you implement any of these plumbing upgrades, you may significantly reduce your water consumption and positively impact the environment. Not only will you be conserving a precious natural resource, but you'll also save money on your water and energy bills in the long run.
