Troubleshooting
Why Is My Water Bill Suddenly So High?
A water bill that jumps with no change in use almost always means a hidden leak, most often a running toilet, an irrigation line, or a slab leak. Shut off every fixture and watch the meter. If it's still moving, you've got an active leak to find.
What to do right now
- Run the meter test: shut off every fixture and appliance that uses water, then watch the meter for 15 minutes. If it moves, you have an active leak.
- Rule out the easy one first, a silently running toilet is the most common cause. Add a few drops of food coloring to the tank. If it shows in the bowl without flushing, the flapper is leaking.
- If the meter moves with everything off and the toilets are fine, suspect an irrigation line or a slab leak. That needs electronic detection to pinpoint.
Likely causes
- A silently running toilet (the most common culprit)
- An underground irrigation or pool line leak
- A slab leak in the supply line under the home
- A dripping or failed pressure-reducing valve

Why Is My Water Bill Suddenly So High?, FAQ
- How do I find the leak driving up my bill?
- Start with the meter test (everything off, watch the dial), then check the toilets. If those are clear, the leak is usually underground irrigation or a slab leak, which we locate electronically.
- Can a slab leak raise my water bill a lot?
- Yes. A continuous slab leak runs 24/7 and can double a bill while staying out of sight, which is exactly why an unexplained spike is worth chasing down fast.
