How to save electricity and water with showerheads and faucets

Save water, save money. You can cut down on water use – and the electricity costs for heating that water – by making a few fixes in your bathroom and kitchen.

Energy-efficient showerheads

Low-flow, energy-efficient showerheads will help cut down on the amount of water you use, without sacrificing water pressure or your shower time.

How to install a low-flow showerhead

In many cases, showers can be the largest single contributor to overall hot water use in a home, accounting for 15% of total household energy use.

Replacing a conventional showerhead with a high-efficiency model is as inexpensive as $15 and is usually a quick and simple job. The payback for installing low-flow showerheads is almost immediate, depending on the frequency of showers.

Energy-efficient tap aerators

Low-flow faucet aerators help you cut down on water usage which will cut down on your electricity costs.

How to install tap aerators

Installing a high-efficiency aerator on your kitchen sink could save you $28 per year in hot water costs.


  • Kitchen or bathroom faucet aerator
  • Thread-seal tape


  1. Unscrew your old aerator in a counter-clockwise direction.
  2. If the grooves on your tap are on the inside, then place rubber washers into the top of the aerator.
  3. If the grooves on your tap are on the outside, use a thin washer.
  4. Gently screw on the new aerator to the faucet and be careful not to cross the threads.
  5. Tighten the aerator by hand.

Fix leaky faucets

A leaky faucet can waste up to 11,350 litres of water each year. Fixing a leaky hot water faucet can save you up to $33 per year in water heating costs.

Worn-out washers are the main cause of leaks in faucets, and a new one generally costs about 25 cents. Here's a step-by-step guide to fixing a leaky compression faucet with handles for hot and cold:


  • Towels
  • Screwdriver
  • Scouring pad
  • Wrench
  • Gasket
  • Plumber's putty


  1. Turn off the water. If you look under your sink, there will be a handle you can use to shut off the water flow.
  2. Plug the sink with a cloth, or towel to stop small parts from going down the drain.
  3. There's likely a decorative piece on the handle, sometimes labelled hot or cold. You'll need to remove this to expose a screw.
  4. Using a screwdriver, loosen the screw and remove the handle. This will expose a valve.
  5. Tighten the valve with a wrench and turn the water back on to see if this fixed the leak. If the faucet is still leaking, turn the water off again.
  6. Remove the valve completely by unscrewing it, and check the threads for corrosion and dirt, then clean with a scouring pad. You'll also want to check the bottom of the valve for a gasket. If it looks deteriorated, remove the screw and replace the entire gasket.
  7. Once the valve has been fixed, apply some plumber's putty along the threads to create a watertight seal.
  8. Put the valve back in place, replace the handle and turn the water back on to check to make sure the leak is fixed.
