Conserving water means using less water. Bathrooms are responsible for a great deal household water usage. Here are a few simple changes that can make a big difference on your water bill: 1. Take showers instead of baths. 2. Limit showers to 10 minutes. 3. Do not leave the water running when you're brushing teeth or shaving at the sink. 4. Fix dripping sinks, tub/shower drips and running toilets. If you really want to step up your game on water conservation, convert your toilet to a dual-flush toilet using a tank rebuild kit from your hardware or home center.
