Quick answer
Where should I start if my water bill suddenly jumped?
Check your meter with every fixture off. If it still moves, you have a leak. Then read our high water bill guide to see whether your utility offers a leak credit and what proof it wants, and the service line guide to learn whether the leaking pipe is yours or the utility’s.

Quick Answers to the Top Questions
Here are short answers to the questions homeowners ask most. Each one links to the full guide or the source behind it.
How do I know if I have a leak?
Turn off every tap and appliance, then watch the meter for 10 to 15 minutes. Movement means water is going somewhere. The EPA’s WaterSense program suggests a toilet dye test too: color in the bowl within 10 minutes means the flapper leaks.
Who pays for a leak in the service line?
Usually the homeowner, for the stretch from the curb stop to the house. Pennsylvania American Water states the owner is responsible from the curb stop into the building. Details by utility are in who owns the water service line.
Will my utility credit a leak?
It depends. Pittsburgh Water may lower a bill caused by an unknown leak once you prove the repair and sign up for leak alerts. Aqua says it offers no leak adjustments in Pennsylvania. See the high water bill guide.
Can a leak cause a sinkhole?
Yes. The PA DEP sinkhole page lists leaking water and sewer pipes as a human cause. Karst ground in southcentral and southeastern Pennsylvania is most at risk.
How deep does the ground freeze?
Roughly 24 to 42 inches across the state, according to Penn State’s housing research center. Shallow and exposed pipes crack first. Prep tips are in how to prevent frozen pipes.
When should I call a professional?
When the meter moves with everything off, a floor feels warm, a ceiling stains, or the yard stays wet. A high water bill investigation or slab leak detection finds the spot before anyone digs. Browse all services or service areas.
Frequently Asked Questions
How much water can a hidden leak waste?
The EPA estimates household leaks can waste nearly 10,000 gallons a year, and 10 percent of homes have leaks wasting 90 gallons or more a day.
What does leak detection cost?
National guides put leak detection alone at about $150 to $600. Our cost guide explains what moves the price up or down.
Do I need a permit or a call to PA811 before digging?
Anyone excavating must notify PA811 at least 3 business days ahead. Dial 811 or 800-242-1776.
Is there a statewide plumbing license in Pennsylvania?
No. Licensing is local, though Philadelphia and Allegheny County license plumbers. Home improvement contractors must register with the Attorney General if they do $5,000 or more of work a year.
What is the first thing to do when a pipe bursts?
Shut off the main water valve, then turn off power to any wet area if it is safe. Call for help after the water is stopped.
Are these guides specific to Pennsylvania?
Yes. They draw on Pennsylvania utility policies, PA DEP and DCNR pages, and state rules on licensing and digging.
