Warrington Township leak detection, 24/7
Leak Detection in Warrington, PA
Warrington has some of the newest housing in Bucks County, and since 2019 its water has come from North Wales Water Authority instead of the township. North Wales says the pipe from the curb to your house is yours, and it offers a leak adjustment once a qualifying leak is fixed. A local technician finds the leak and documents the repair you need.
- Service line, slab and hidden wall leaks in 1990s and 2000s homes
- Written findings to support a North Wales Water leak adjustment request
- Neshaminy, Tradesville, Pleasantville, Palomino Farms and all of Warrington
Calls answered day and night. Emergency? Shut off your main valve first, then call.
Quick answer
Who fixes a leak in my Warrington water service line?
You do, through a plumber you hire. North Wales Water Authority says the line from the curb to your house is on your property and owned by you. Its optional Water Service Maintenance Program, about $10 a year for homes, covers that line from the curb stop to near the house. Leak detection pinpoints the spot first.

Why Warrington homes leak: newer houses, more fittings
Warrington is younger than most of Bucks County. Its median home was built in 1989, and nearly 47 percent went up between 1990 and 2019. Newer homes leak differently from old ones: fewer corroded pipes, more failed fittings, appliance lines, shower pans and irrigation.
Census data compiled by Point2Homes (ACS 2019 to 2023) shows 1,876 Warrington homes built from 2000 to 2009, the largest decade at 22.4 percent, followed by 1,384 from the 1990s. Only about 14 percent predate 1960. The Census Reporter profile counts about 9,650 housing units.
| When built | Share of homes | Usual leak points |
|---|---|---|
| Before 1960 | 14.3% | Old service lines, galvanized or patched pipes, original drains |
| 1960 to 1989 | 37.4% | Copper joints, water heater connections, basement floor lines |
| 1990 to 2009 | 38.9% | Fittings in walls and ceilings, plastic supply lines, shower pans, irrigation |
| 2010 and later | 9.3% | Appliance hoses, installation defects, yard hydrants |
In a 1990s or 2000s house, the leak is often upstairs or behind finished drywall rather than under a floor. A dripping fitting over a ceiling can soak insulation for weeks before a stain shows.
Older homes on slabs still get slab leaks, and our guide to the signs of a slab leak covers those.
Where leaks hide in a 1990s or 2000s Warrington house
In newer homes, start upstairs and work down. Bathrooms over finished rooms, laundry rooms, refrigerator lines, water heaters and irrigation account for many hidden leaks in houses of this age.
- Second floor bathrooms: check for ceiling stains below tubs, showers and toilets.
- Laundry rooms on upper floors: look at the washer hoses and the drain box in the wall.
- Kitchen: the refrigerator ice maker line and the dishwasher supply are common slow leaks.
- Basement: the water heater relief valve, softener drain and any finished walls around the main.
- Yard: irrigation heads, valve boxes and the backflow device.
A slow drip behind drywall can run for weeks without a stain. Moisture meters and thermal imaging find it without opening the wall. When a shower is the suspect, a flood test of the pan separates a pan leak from a valve or drain leak. See our shower and tub leak detection page.
The 2019 handover: what changed when North Wales Water took over
Warrington Township used to run its own water system. On October 1, 2019, North Wales Water Authority took it over, and sewer moved to the Bucks County Water and Sewer Authority in November 2019. If your leak questions involve a bill from before then, the township still handles those old accounts.
The township’s water and sewer contacts notice lists North Wales Water Authority at 267-482-6940 for water and BCWSA at 215-343-3946 for sewer. It says to call the township at 215-343-1800 about water bills before October 1, 2019 or sewer bills before November 14, 2019.
North Wales Water’s Warrington page says rates had reached $7.16 per thousand gallons before the takeover, partly because of township surcharges. It says it dropped the surcharges and cut the rate about in half, to $3.60 per thousand gallons, and credited $364.90 to each of 7,571 accounts that were active before the change.
About 97 percent of North Wales Water’s supply comes from the Forest Park Water Treatment Plant in Chalfont, with wells for backup, according to the same page. Several old township wells are being fitted with filtration so they can serve as emergency supplies.
PFAS and the old township wells
North Wales says several township wells were contaminated with PFAS before it took over, allegedly from firefighting foam at a former military facility near Route 611 and County Line Road. Those wells were shut down and stay closed until filtration is installed and testing confirms compliance. Its PFAS FAQ says it has tested the Warrington wells since June 2020.
PFAS is a drinking water quality issue. It does not cause leaks or damage household pipes. If you have questions about your water, call North Wales Water; if water is escaping somewhere, that is a leak detection job.
Signs of a hidden leak in a Warrington home
In Warrington’s newer homes, watch for ceiling stains, warm or damp spots near bathrooms, a meter that moves with everything off, and soggy lawn over irrigation or the service line.
Bill and meter
- Gallons up with the same people at home
- Meter moving with every tap off
- Family of four over 12,000 gallons a month in winter (EPA)
Inside the house
- Ceiling stain under a bathroom or laundry
- Soft drywall or lifting floor near a shower
- Hissing behind a wall
- Musty smell in a finished basement
Yard and curb
- Soft or sunken lawn between house and street
- Water near the curb stop
- Irrigation zone that stays soggy
Pool and outdoor
- Pool dropping faster than evaporation
- Wet spots along pool lines
- Yard hydrant that drips or won’t drain
North Wales Water’s billing FAQ lists the common causes of a high bill: leaks in toilets, spigots, faucets and showerheads, more people at home, lawn watering, filling a pool, and a bad softener or appliance.
Leak detection services that fit Warrington homes
Given Warrington’s newer housing, these services fit best: hidden wall and ceiling leaks, shower and tub leaks, service lines, irrigation and high bill investigations.
- Hidden wall and ceiling leak detection for finished basements and second floor bathrooms.

How a Warrington leak detection visit works
The technician confirms the leak at the meter, isolates sections of the plumbing, then pinpoints the spot with listening, imaging and tracer tools. You get a marked location and a written report you can keep for an adjustment request.
1
Confirm
Read the meter with all water off. Test toilets, softeners and the water heater.
2
Isolate
Close the main and branch valves to separate the service line, inside lines and irrigation.
3
Pinpoint
Use acoustic listening, moisture meters, thermal imaging, tracer gas or flood tests.
4
Report
Mark the spot and write up the readings, photos and repair options.
What the written report includes
- Meter readings and measured leak rate
- Which line or fixture is leaking
- Marked location with photos and thermal images
- Details that support a North Wales Water leak adjustment request
Who owns the service line, and how North Wales Water handles a high bill
North Wales Water says the service line from the curb to your house is on your property and owned by you. It also has a leak adjustment policy: if a qualifying leak is found and repaired, you may be eligible for a bill adjustment.
The Water Service Maintenance Program page says the pipe from the curb to the house is yours, and without the program you pay to repair leaks or breaks in it. The program covers damage from the curb stop to within three feet of the outside wall for $10 a year for homes. It does not cover frozen lines, and homes with meter pits are not eligible.
Its leak detection and adjustment page says customers may be eligible for an adjustment after a qualifying leak is repaired, with the details in a separate policy document. It also says that if you still hear running water after closing the main shutoff, the outside line may be leaking and you should call 215-699-4836.
| Part of the system | Who is responsible | What to do |
|---|---|---|
| Water main | North Wales Water | Report problems at 215-699-4836, answered 24/7 |
| Curb to house | Homeowner | Leak detection, then a plumber; covered if enrolled in the maintenance program |
| Inside plumbing | Homeowner | Leak detection, then a plumber |
| Sewer | BCWSA | Call 215-343-3946 for sewer service |
| Bills before Oct 1, 2019 | Warrington Township | Call 215-343-1800 |
Steps after a high North Wales Water bill
- Check for the common causes: toilets, spigots, softener, pool fill, irrigation.
- Read the meter overnight with nothing running.
- If it moved, book leak detection and get a written report.
- Have the leak repaired and keep the plumber’s invoice.
- Ask North Wales Water about its leak adjustment policy and send your documents.
- Check your bill for a Water Service Maintenance Program line if the leak was in the service line.
See our guides to high water bills and leak credits in Pennsylvania and who owns the service line.
Is the $10 service line program worth it?
For most single family homes without a meter pit, the North Wales program is cheap protection against a costly repair. It costs $10 a year and covers service line damage from the curb stop to within three feet of the house. Read the exclusions first: frozen lines are not covered.
The figures below all come from the program page. Residential customers pay $10 a year, billed as $2.50 a quarter or $0.83 a month. Small commercial connections pay $18 a year and larger ones pay $30.
| Question | Answer from North Wales Water | What it means |
|---|---|---|
| What is covered? | Damage from the curb stop to within three feet of the outside wall | Most of the buried yard line |
| What is not covered? | Frozen water lines; homes with meter pits | Freeze damage and meter pit homes stay on you |
| How do I join? | Fill out the application; no need to reapply once approved | One time paperwork |
| How do I know I am enrolled? | A Water Service Maintenance Program line item on the bill | Check before you call a plumber |
The last three feet next to the foundation, and the line inside the house, stay your responsibility either way. Leak detection still matters with the program, because someone has to show where the leak is and whether it falls inside the covered stretch.
What a leak costs on a Warrington bill
Using the $3.60 per thousand gallons North Wales reported after the 2019 takeover, a small 0.1 gallon a minute leak costs about $15.55 a month in water usage, and a cracked service line can cost hundreds. Check your current rate before relying on these numbers.
North Wales publishes current charges in its Rates and Regulations document (effective January 1, 2026), which we could not read. The table uses the $3.60 rate from its Warrington page as a worked example. It covers usage only, not base or sewer charges.
| Leak rate | Gallons in 30 days | Usage cost at $3.60 per 1,000 gallons |
|---|---|---|
| 0.1 gallon per minute | 4,320 | 4.32 x $3.60 = about $15.55 |
| 0.25 gallon per minute | 10,800 | 10.8 x $3.60 = about $38.88 |
| 1.5 gallons per minute | 64,800 | 64.8 x $3.60 = about $233.28 |
| 3 gallons per minute | 129,600 | 129.6 x $3.60 = about $466.56 |
Leak detection alone usually runs about $150 to $600 according to This Old House, which puts average slab leak repair near $2,300. Pennsylvania Leak Detection quotes your visit by phone. Our cost guide has more detail.
Warrington communities, ZIP codes and local notes
Warrington Township uses ZIP codes 18976 and 18914 and grew from four early villages. Route 611 and Street Road are the main reference points.
The township history says Warrington was founded in October 1734. Its early villages were Warrington, Neshaminy (once Warrington Square), Tradesville (once Stuckert’s Corner) and Pleasantville (also called Eureka). Frog Hollow and Palomino Farms are other named areas.
| Area or landmark | Notes | Worth telling the technician |
|---|---|---|
| Warrington village | Original village; Route 611 (Easton Road) runs through the east side | Year built and where the meter is |
| Neshaminy | Once called Warrington Square | Whether a basement stays damp after rain |
| Tradesville and Pleasantville | Early villages, once Stuckert’s Corner and Eureka | Any older service line or old well connection |
| Palomino Farms and Frog Hollow | Named areas of the township | Finished basement, irrigation, meter pit or inside meter |
| Street Road and Bristol Road | Route 132 crosses the middle; Bristol Road runs along the northeast boundary | Which ZIP code is on your mail |
Little Neshaminy Creek, Mill Creek and Park Creek run through the township, and Central Bucks High School South is one of its best known landmarks.
Freeze notes for Warrington
Frozen lines are excluded from the North Wales service line program, so freeze protection is on you. Focus on outdoor spigots, irrigation backflow devices, garages and lines on outside walls.
Penn State puts Pennsylvania frost depth at about 24 to 42 inches. Newer homes still freeze where pipes run through unheated garages, bonus rooms over garages and crawl spaces.
- Blow out irrigation and drain the backflow preventer before the first hard freeze.
- Shut and drain outdoor spigots and disconnect hoses.
- Keep the heat on in bonus rooms over garages.
- After a thaw, use frozen and burst pipe leak detection if the meter keeps moving.
North Wales Water’s emergency shutoff page says everyone at home should know where the main shutoff is, usually near the meter where the line enters. It offers a free tag for the valve.
Gas leak safety in Warrington
If you smell gas, leave the house, then call 911 or PECO at 800-841-4141 from outside. Do not use switches or phones inside.
Smell gas? Leave first.
Leave the door open behind you and call PECO at 800-841-4141 or 911 from a safe distance. PECO serves natural gas across most of Bucks County.
Customer-side leaks and failed pressure tests during remodels are covered by gas line leak detection after the utility has made the home safe.
Quick checks before you call
Run these checks first and write down what you find.
- Turn off all water use, including ice makers, softeners and irrigation.
- Watch the meter for 15 minutes. Any movement means water is leaving.
- Close the main shutoff. If you still hear water or the meter moves, suspect the service line.
- If it stops, the leak is inside. Dye test the toilets; color in the bowl within 10 minutes means a leak, per the EPA.
Water through a ceiling? Shut the main and call our 24/7 emergency line. See our homepage or the Bucks and Montgomery area page. EPA tips are on its Fix a Leak Week page.
