If your water bills have been increasing and it’s not because of a rate hike or more usage, there are a few possibilities. First, check to make sure all of your fixtures are off and then look at the meter. If the meter is still running, that indicates a leak somewhere on your property. Check to see if any of your fixtures are leaking (running toilet, leak below the sink, or water in the crawlspace).
If you do not see any visible water leaking, you may have a main line water leak or hidden pipe leak. You should immediately call a trusted plumbing contractor to assess the situation.
