High Water Bill & Meter Leak Testing in West Chester, PA
A jump in the water bill is usually a leak. The meter proves it. Then the job is to find where the water is going.

Is it a leak? A fifteen-minute meter test
Stop all water use
Turn off taps, the dishwasher and the washing machine, and check that no one is showering.
Record the meter
Photograph the dial or the leak indicator.
Wait fifteen minutes
Use no water at all.
Compare
Movement means water is leaving the system after the meter.
Read the bill before you chase the leak
Start with the usage line, not the dollar total. A bill can rise because the billing period was longer, because a read was estimated and then corrected, or because rates changed. Compare the gallons or units for the same month last year. If usage is up by a third or more with nothing else changed, a leak becomes the likely explanation.
Look for the date the jump began. A sudden step up points to something that broke on a specific day, such as a toilet flapper, a hose left running or a pipe that split. A slow climb over several bills points to a growing leak or a worn fixture getting worse.
Where unexplained water usually goes

Questions for the utility
Aqua Pennsylvania's customer line is 877-987-2782. If your meter is moving but you cannot find the leak, ask the utility whether a leak adjustment is available and what documentation it wants. A plumber's written findings, with date and location of the leak, are often useful for that conversation.
Seasonal changes matter too. Filling a pool, watering a new lawn or a house full of guests can all raise a bill without any leak.

Small fixes that often explain a big bill
These are the most common culprits, and most take minutes to check.
If every one of these is clear and the meter still moves with everything off, the leak is hidden. That is when a plumber with detection equipment saves you from guessing, and when the written findings help you ask the utility about an adjustment.
When the leak is already fixed but the bill is still high
A bill can stay high for one cycle after a repair because utilities bill for the period that included the leak. Look at the next full cycle for the real result. If usage has not come down, a second leak may exist, and the meter test is worth repeating.
Keep the plumber's invoice and the date of the repair with the bill that included the leak. If the utility offers an adjustment, those two documents are usually what it asks for.
What to do while you check for a leak
Close the main if you hear water running with everything off and keep away from wet electrical areas. Water meters are tested to accuracy standards, so a moving dial with all fixtures off points to a leak, not a meter error.
A meter that moves with everything off in Westtown points to a leak after the meter, and the township page has a seasonal list of places to check. Start with toilets and outdoor taps.
A student rental near campus can show a high bill when a toilet runs unnoticed during a quiet week. Read the meter with every fixture off, then again an hour later, and report the difference.
