The water service line runs from the city water main in the street, through a shutoff and meter, and into your home. If it is leaking or has broken in Darien, call (630) 822-9290. Our emergency line is answered 24/7, and a gushing line should not wait until morning.
While you wait, find your main shutoff, usually near the water meter in the basement, and turn it off. That stops water from entering the house. If water is flooding the yard or basement, stay away from electrical panels and outlets that are wet.
What to do right now if the line has failed
Shut off the main valve first. Turn it clockwise until it stops. If it will not turn, or you cannot find it, call dispatch and we will talk you through it.
Then open one faucet low in the house to relieve pressure, and take photos of any damage for your insurer. Do not dig around the line yourself, since gas, electric and other utilities may share the area.
Signs of a service line problem
Service line leaks are underground, so you often notice the effect before you find the source.
- Pressure drops at every faucetA leak before the house takes water out before it arrives.
- Meter keeps moving with everything offClose all taps and check the meter. Movement means water is going somewhere.
- Wet or sunken patch in the yardA soggy spot that never dries, or grass that stays greener along a line, can mark a leak.
- Water bill jumps without a reasonA steady leak adds up over a billing cycle.
- Dirty or discolored waterA break can let sediment into the line.
Repair or replace the service line
The condition of the line and the type of pipe decide. Here are the usual cases.
| Situation | Usual approach | Reason |
|---|---|---|
| One leak at a fitting or short section | Spot repair | The rest of the pipe is sound |
| Several leaks over the years | Replace the run | Repeating repairs on aging pipe is wasteful |
| Old galvanized steel line | Replace | Corrosion narrows the bore and reduces flow |
| Suspected lead pipe | Replace after identifying | Lead needs proper handling and testing |
| Line frozen and cracked | Repair or replace the damaged run | Check depth and cover as part of the fix |
A plumber confirms the pipe material and condition on site.
What Darien's own water records say
Darien buys treated Lake Michigan water from the City of Chicago, with master meters at the Plainfield Rd and 75th St pump stations. The City reports it has built a service line material inventory and is still filling in missing records.
That matters if you are unsure what your line is made of. Ask the City water operator at (630) 353-8105 what is on file for your address. We then confirm the material on site before we recommend a repair.

How we fix a service line
- 1
Confirm the fault
We check the meter, the pressure and the line path to locate the leak. For tricky ones, our leak detection work narrows the spot.
- 2
Locate utilities
Underground utilities are located before any digging.
- 3
Choose the method
We compare a spot repair, a trench replacement and trenchless options.
- 4
Permit and shutoff
Plumbing changes in Darien need a permit, so we work with the Community Development Department. Water gets shut off for the work.
- 5
Restore and test
We pressure-test the new pipe, flush the line and check the meter reads steady. New piping and fittings follow the standards in the Illinois Plumbing Code (Title 77, Part 890 of the Illinois Administrative Code) and the pipe manufacturer's guidelines for joints.
What drives the cost of a service line job
The scope varies a lot from one property to the next. You hear a clear price before work starts.

Lead pipes and your water line
If your line is old, you may wonder whether it contains lead. Only testing and a look at the pipe can say for sure. Do not assume either way.
If we find lead during a repair, we will explain it and talk through replacement. For a broader replacement of failing supply lines inside the house, our whole house repiping page explains that work.
Freezing, low pressure and what to check first
Not every pressure problem is the service line. Check the main valve first, since a partly closed valve restricts flow. If only the hot side is weak, the issue may be the water heater, and our water heater repair page can help.
If pressure is low everywhere and the meter runs, the service line becomes the likely suspect.
Water service line questions from Darien homeowners
Yes. Our line is answered 24/7. Call (630) 822-9290, shut off the main valve if you can, and we will help with the next step. Same-day appointments are offered when available.
It is usually in the basement near where the line enters, close to the meter. In homes on a slab it may be in a utility closet. If you cannot find it, tell dispatch.
Responsibility generally splits between the City's side and the homeowner's side, but the point varies. Ask the City of Darien at (630) 353-8105 where it ends for your address.
Sometimes. Trenchless methods can limit digging when conditions suit them. Depth, soil and other utilities decide.
It depends on the scope. A spot repair is usually shorter than a full replacement. We tell you the expected window before we shut off the water.
