Think You Have a Leak? Check This First
A quick check at home tells you whether water is going somewhere it should not.
1. Read Your Water Meter
Turn off every tap and appliance, note the meter reading, wait one to two hours without using water and read it again. If it moved, you have a leak.
2. Check the Toilets
Put a few drops of food coloring in each toilet tank. If color shows up in the bowl within 15 minutes without flushing, the flapper is leaking.
3. Call (610) 489-2717
If the meter moves and the toilets are fine, the leak is hidden. We will find it.
How We Find Hidden Leaks
Most leaks are not where the water shows up. Water runs along pipes, framing and slabs before it stains a ceiling or soaks a floor.
We start with a pressure test to confirm the leak and find which line it is on. Then we use listening equipment, moisture meters and thermal imaging to pinpoint the spot, so we open only the small area needed to reach the pipe.
Pressure Testing
Confirms a leak and which line it is on.
Acoustic Listening
Picks up the sound of water escaping a pipe.
Thermal Imaging
Shows hot water leaks and damp areas behind walls.
Moisture Mapping
Traces wet framing and drywall to the source.
Tell us when you first noticed the problem and whether your water bill changed. It helps narrow down where to look.
Leaks We Find and Fix
Once we find the leak, we explain the repair before any work starts. Small leaks are usually fixed on the spot; old pipes with repeated leaks may be better replaced.
After the repair we pressure test the line again, so you know the leak is gone.
Leaks Inside Walls
Supply and drain line leaks behind drywall.
Slab Leaks
Water lines leaking under concrete floors.
Ceiling Leaks
Bathroom and supply line leaks from the floor above.
Outdoor Water Lines
Service line leaks between the meter and the house.
A leak under a slab or in an outdoor water service line can raise your bill for months without any visible sign. Check your meter twice a year.
Signs of a Hidden Leak
Hidden leaks waste water and slowly rot framing, subfloors and drywall. Older copper and galvanized lines, common in many Montgomery County homes, develop pinhole leaks with age.
Watch for these signs and call before the damage spreads.
Shut off the main valve and call (610) 489-2717. We answer 24/7.

Leak Detection FAQs
Turn off all water, note your meter reading and check it again after one to two hours of no use. If it changed, water is leaking somewhere. A higher water bill, the sound of running water and damp spots are other signs.

Usually only a small access opening at the leak itself. Pinpointing the leak first avoids opening walls in the wrong place.
Often, yes. A running toilet or a hidden supply line leak are the most common causes. Check the toilets with food coloring and do the meter test; if the meter still moves, call us.
