Suspect a water line leak?
Check these before you call
- Turn off every fixture and look at the water meter. Movement means water is being lost.
- Walk the line from the street to the house for soggy ground or pooling.
- Ask a neighbor whether they have water. A whole street outage points to Aqua.
- Note any pressure change and whether Aqua has worked on your street recently.
- Call (610) 788-0042.

Straight answers
Quick answers about water line plumbing in T/E
What counts as the water line?
The service line that runs from the utility connection at the street, past the curb stop and the meter, to the main shutoff valve inside your house.
Is it mine or Aqua’s?
Usually the utility maintains the main and the connection up to the curb stop, and the homeowner owns the line from there into the house. Confirm your exact boundary with Aqua.
What are the warning signs?
Soggy ground between the street and the house, a hissing meter, a jump in the water bill, or pressure that has dropped.
Do you replace main shutoff valves?
Yes. An old gate valve that will not close is one of the most common and most important small repairs in older T/E homes.
How it works
The parts of your water service, from the street to the house
Knowing the parts helps you describe the problem and understand who is responsible for what.
| Part | Where it is | What it does |
|---|---|---|
| Water main | Under the street | Aqua’s pipe that serves the whole street |
| Corporation stop | At the main | The connection where your service line taps into the main |
| Curb stop | Near the property line, often under a small cover | A valve that can shut off water to the property from outside |
| Water meter | In the basement, or in an outdoor meter pit on some properties | Measures the water you use |
| Service line | Buried between the curb stop and the house | Carries water to the house; usually the homeowner’s responsibility |
| Main shutoff valve | Inside, where the line enters, usually on the wall facing the street | Shuts off water to the whole house |
| Pressure reducing valve | Near the main shutoff in some homes | Lowers street pressure to a safer household level |
Warning signs
Signs your water service line needs attention
Wet or unusually green ground
A strip of lawn that stays soggy or greener than the rest, especially along the path from the street to the house, often marks a leaking service line.
A moving meter
With every fixture and appliance off, the meter should not move. If the dial or leak indicator keeps turning, water is escaping somewhere.
A higher water bill
A bill that jumps without a change in how you use water is one of the first signs of an underground leak.
Pressure changes
Pressure that drops throughout the house, or sputtering faucets, can point to a leak or a restriction in the line.
Hissing at the meter or valve
A constant hiss near the meter or main shutoff when nothing is running often means water is moving through a leak.
Water in the basement near the entry
Damp walls or water near where the service line comes through the foundation can mean a leak at the entry point or a failed seal.
Responsibility
Your side of the curb vs. Aqua’s side
Usually Aqua’s
- The water main under the street
- The connection at the main
- Service up to the curb stop, in general
- Water quality and taste issues from the source
If water is bubbling up in the street or the whole neighborhood is out, call Aqua using the number on your bill.
Usually the homeowner’s
- The service line from the curb stop to the house, in general
- The main shutoff valve inside
- Any pressure reducing valve
- All plumbing inside the house
Confirm the exact boundary for your address with Aqua. We can locate a leak and tell you which side of the line it is on before anyone digs.
Street work
How Aqua’s main replacements affect your water line
Aqua has been replacing old cast iron water mains with ductile iron across Tredyffrin. The work has included Yellow Springs Road, Salem Way, and Salem Court, and more recently Glenhardie Road between Walker Road and the Turnpike overpass and Bear Hill Road (Route 252) between Heatherstone Drive and Old Cassatt Road, with Easttown streets in the same program. The new mains are made from nearly 90 percent recycled metal.
Discolored water
Main work can stir sediment into your lines. Running cold water for a few minutes usually clears it.
Clogged aerators and screens
Loosened sediment collects in faucet aerators, showerhead screens, and appliance inlet screens. Cleaning them restores flow.
Pressure changes
If pressure stays different for more than a week or two, the disturbance may have exposed a weak spot in your service line, a fitting, or your pressure reducing valve.
Winter risk
Meter pits and frozen service lines
On some T/E properties the water meter sits in an outdoor pit rather than in the basement. That pit is designed to stay above freezing below ground, but only if the lid is intact. Aqua’s winter advice specifically tells customers to check that meter pit lids are not broken or missing.
During long cold spells, a cracked or missing lid lets frigid air reach the meter and its connections, which can freeze and crack. During the late January 2026 cold, Philadelphia’s water department warned that pipes can be seriously affected after about three days below freezing, and outdoor components are the most exposed.
The valve that matters most
Main shutoff valve replacement
Many older T/E homes still have the original gate valve at the main. After decades of sitting open, gate valves often will not close fully, or they break when someone finally tries to turn them in an emergency.
- Replacing it with a quarter turn ball valve that closes with a simple 90 degree turn
- Adding a valve on both sides of the meter where practical
- Labeling the valve so everyone in the house can find it
- Testing it once or twice a year
Options
Repairing or replacing a water service line
Spot repair
When a leak is isolated and the rest of the line is in good condition, repairing just the failed section is usually the most economical option. It is common after damage from digging, root intrusion at one point, or a failed fitting.
Full replacement
When the line is old galvanized steel that is corroding throughout, when leaks keep recurring, or when the line is too small for the home’s needs, replacing the whole service line is the better investment.
Open trench
A trench from the curb stop to the house is straightforward and allows full inspection. It makes the most sense when the route is clear lawn or when other work is already planned.
Trenchless methods
Depending on soil, the existing pipe, and what is in the path, a new line can sometimes be pulled through with only small access pits at each end, sparing driveways, walkways, and mature landscaping.
Before any digging, underground utilities must be marked through PA One Call, which you can reach by dialing 811. We confirm that is done before excavation starts.
Step by step
What happens during a water service line replacement
- Locate and confirm. We confirm the leak or failure and trace the route of the existing line from the curb stop to the house.
- Mark the utilities. Underground lines are marked through PA One Call (811) before any digging.
- Plan the route and method. Open trench or trenchless, based on the soil, the existing pipe, and what is in the way.
- Coordinate the shutoff. Water is shut off at the curb stop, and you know in advance how long you will be without it.
- Install the new line from the curb stop to the house, with a proper seal where it enters the foundation.
- Replace the main shutoff if it is old, so the new line has a valve that works.
- Test, flush, and restore. The line is pressure tested and flushed, and the ground is backfilled.
Make it last
How to protect your water service line
Around the yard
- Call 811 before planting trees, installing fences, or digging for any project
- Keep large trees away from the service line route where possible
- Know where the curb stop cover is and keep it clear of mulch and soil
- Keep the meter pit lid intact and visible
Inside the house
- Test the main shutoff once or twice a year
- Watch for pressure changes and a rising water bill
- Have a pressure reducing valve checked if pressure seems high
- Insulate the section of line where it enters an unheated space
What is in the ground
Service line materials in T/E homes
Copper
Common in many homes and long lasting, though it can develop pinhole leaks and is affected by aggressive soil conditions over time.
Plastic
Newer service lines are often plastic, which resists corrosion and is used in many replacements, including trenchless ones.
Galvanized steel
Found in some older homes. It corrodes from the inside, which reduces flow and eventually leads to leaks, often at threaded joints.
Federal rules have required water utilities to inventory the materials of service lines in their systems. If you are unsure what yours is made of, Aqua may be able to tell you what its records show, and we can look at the line where it enters your house.
Buying or selling
Water line checks before you buy a T/E home
Most home inspections look at the plumbing inside the house but say little about the pipe buried between the street and the foundation. In an older neighborhood, that line may be as old as the house.
Look where it enters
The material of the service line where it comes through the foundation, and the condition of the main shutoff, tell you a lot about what is underground.
Run a meter test
With all fixtures off, the meter should stay still. A moving meter in a vacant house is a red flag worth investigating before closing.
Ask about records
Aqua may be able to share what its service line inventory shows for the address, and sellers may know whether the line has been replaced.
Pricing
What water line work costs in Tredyffrin
Length and depth
The longer and deeper the line, the more labor and material the job takes.
What is in the way
Driveways, walkways, retaining walls, trees, and landscaping affect the method and the cost of restoration.
Repair vs replacement
Fixing one leaking section costs far less than replacing the whole line. We give you both prices when both are realistic.
We locate the problem first, explain what we found, and give you the price before any digging starts.

Frequently asked questions
Frequently asked questions about water line plumbing in Tredyffrin, PA
Answers by John, Tredyffrin Easttown Plumber.
What is a water service line?
It is the pipe that carries water from the utility main in the street to your house. It usually passes a curb stop valve near the property line, runs through or past the water meter, and ends at the main shutoff valve inside the house.
Who is responsible for the water line, me or Aqua?
In general, the utility maintains the main and the connection up to the curb stop, and the line from there into the house is the homeowner’s responsibility. Confirm the exact boundary for your address with Aqua before assuming who pays.
What are the signs of a water service line leak?
A soggy or unusually green strip of lawn, water pooling between the street and the house, a hissing sound at the meter, a water bill that jumps, or a meter that moves with every fixture off.
Why did my water pressure drop after Aqua replaced the main?
Main work can loosen sediment that clogs aerators, showerhead screens, and pressure reducing valves, and it can stress older service lines and fittings. Clean the aerators first. If pressure stays low for more than a week or two, have the line and valve checked.
What is a meter pit?
On some properties the water meter sits in an outdoor pit with a lid instead of inside the basement. Aqua’s winter guidance tells customers to make sure meter pit lids are not broken or missing, because cold air reaching the meter can freeze it and the connections.
My main shutoff valve will not turn. What should I do?
Do not force it, since old valves can break and start leaking. Have it replaced with a quarter turn ball valve during a planned visit, so it works when you actually need it.
Do I need to call 811 before a water line is dug up?
Yes. Pennsylvania requires buried utility lines to be marked through PA One Call before excavation. Dial 811 or have your contractor arrange it before any digging.
Can a water line be replaced without digging up my whole yard?
Sometimes. Depending on soil, the existing line, and what is in the way, trenchless methods can replace a line with only small access pits. In other cases an open trench is the practical choice. We explain both when both are possible.
What is my service line made of?
Common materials include copper, plastic, and in older homes galvanized steel. Federal rules have required water utilities to inventory service line materials, so Aqua may be able to tell you what its records show for your address. We can also look where the line enters the house.
How much does water line repair cost in Tredyffrin?
It varies widely with the length of the line, the depth, what is in the way such as driveways or landscaping, the method, and permits. A repair of one leaking section costs far less than a full replacement. You get the price before work starts.
Is a yard leak an emergency?
If water is flowing heavily, you have lost pressure, or water is getting into the basement, treat it as urgent and close the main shutoff. A slow seep is still worth fixing soon, because it wastes water and can undermine walkways and driveways.
Do you work on water lines in both Tredyffrin and Easttown?
Yes, across Wayne, Strafford, Chesterbrook, Paoli, Berwyn, Devon, and the rest of both townships.
What is a curb stop and can I use it?
A curb stop is a valve near the property line that can shut off water to the whole property from outside. It usually sits under a small metal cover and needs a special key. In most cases the utility or a plumber operates it, and you should use your inside main shutoff for emergencies.
Should I have the water line checked before buying an older home?
It is worth it. A quick look at the service line material where it enters the house, the condition of the main shutoff, and a meter test with all fixtures off can reveal problems that a standard home inspection may not cover.
Wet yard, high bill, or a valve that will not turn?
We find the leak, tell you whose it is, and give you options before anyone digs.
