If you’re noticing an unusual increase in water bills, it could be a leak! For example, toilets take about 30% of a home’s water use so a leaky or running toilet can cause a problem.
The same thing goes for other fixtures such as sinks or pipes with a pesky drip. Another thing to check is if your home has outdated plumbing equipment.
Lastly, reflect on your water use. New water-intensive items or wasteful water use will contribute to a higher water bill.
