High water bill? Water meter leak detection in La Mirada
A climbing water bill with no visible leak almost always means water is escaping somewhere you cannot see. Your meter tells us where to look.
A water bill that climbs with no visible leak is one of the most common reasons people call us in La Mirada. A pinhole leak inside a wall weeps slowly and stays hidden for weeks. A silently leaking toilet flapper runs into the bowl and down the drain, invisible unless you check for it specifically. Your water meter cannot be fooled the same way — it registers every gallon passing through whether or not you can see where that water went.
Suburban Water Systems delivers your service here, and the meter test is the fastest, cheapest diagnostic step before we ever send a truck. Turn off every fixture and appliance that uses water, including anything on an automatic cycle like a sprinkler timer. Note the meter reading, wait at least two hours without using any water, then read it again. Any movement means water left the system somewhere between the meter and your fixtures.
What the flow tells us
Fast leak vs. slow leak
- A fast, steady flow points toward a supply-side leak — a slab, yard, or service line failure running continuously.
- A slower or intermittent flow more often points toward a fixture, most commonly a silently leaking toilet flapper.
- A bill that has been high for several cycles usually means a smaller, slower leak rather than a sudden failure.
Common causes
What is usually behind it
Pinhole leaks are common here given the 1950s and 1960s copper still in the ground, corroded by six decades of hard imported water — see our pinhole leak page. Silent toilet leaks are next most common; food coloring in the tank showing up in the bowl within ten minutes confirms it. Once you have confirmed loss with the meter test, we combine that flow-rate data with acoustic listening and moisture mapping to pinpoint exactly where the water is going, rather than guessing based on the bill alone.

Questions we hear
Answered for La Mirada homeowners
My bill has been high for months, not just one cycle. Does that matter?
It usually points to a smaller, slower leak rather than a sudden failure, since a large leak tends to show up dramatically within one cycle.
Could this just be a meter reading error?
It happens, but rarely. If your own meter test confirms flow with everything off, that rules out a reading error and confirms real water loss somewhere in your system.
How much water does a running toilet actually waste?
A worn flapper can waste 200 gallons a day or more, silently, enough on its own to visibly move a monthly bill.
