The water service line, or water line, is the buried pipe that brings water from the meter at the street into your house. A break there is an emergency. You may see a flooded yard, hear water running or lose pressure at every tap. Close the house shutoff and call our 24/7 line. Same-day and after-hours visits are scheduled when a plumber is available.
Water line repair patches a failed section. Water line replacement swaps the entire run, by digging a trench or by pulling a new pipe through the old path without opening the whole yard.
Broken water line: what to do right now
Close the house valve
This valve is at the house, often by a hose bib or in the garage. It stops water from the house side.
Check the meter
If the meter still turns with the house valve closed, the leak is in the line before it. Close the meter valve only if you have a key or a wrench made for it.
Keep people away from soft ground
Wet soil above a trench can give way. Keep children off the area.
Call and photograph
Take photos of the wet ground and the meter reading for your records.
If the break is on the utility side of the meter, the water district handles it. Helix Water District serves Lemon Grove, so call Helix for a leak between the main and the meter. Between the meter and the house, the line is generally the owner's.
Signs of a failing water line
Low pressure everywhere
A leaking or corroded service line cannot carry full flow to the house.
Wet patch with no rain
A damp or sunken spot in the yard along the pipe path.
Rusty or cloudy water
Old steel service lines corrode from within and release rust.
High bill
A leak between meter and house pays for itself on the bill.
Repair, replace or reroute
| Option | When it fits | Consider |
|---|---|---|
| Spot repair | One short break in sound pipe | Needs a small excavation |
| Trenchless replacement | Pipe is failing along its length and the yard is finished | Needs entry and exit pits and a suitable path |
| Open trench replacement | Pipe is shallow or the route is simple | Most disruptive to landscaping |
| New route | Old path is blocked by structures | Needs a plan and sometimes a permit |

How we find and fix the break
Test the line
We isolate the line and watch pressure to learn whether it holds.
Pinpoint the leak
Acoustic equipment on the ground narrows the spot.
Expose and repair
We dig only as needed, cut back to sound pipe and join it with fittings made for buried service.
Backfill and test
The trench is closed in layers and the line is pressure tested.
Lemon Grove notes
Lemon Grove covers 3.88 square miles, and the service lines under its older streets were laid at different times. Steel, copper and plastic all turn up. Ask us which pipe your house has, because that decides the repair.
Permits for digging in the street or the parkway are handled by the City of Lemon Grove, so we ask the city which permits apply to your address. We do not guess at those rules.
What water line repair costs
You see the cost before work starts. Insurers sometimes cover resulting damage, but the buried pipe is usually not covered. Ask yours before the job.
Codes, permits and licensing
Plumbing in California follows the California Plumbing Code, which is based on the Uniform Plumbing Code (UPC). For water line repair, materials, venting and connections should meet that code, and larger jobs may need a permit from the City of Lemon Grove building department.
Plumbing contractors in California hold a C-36 license from the Contractors State License Board, and you can check any license at cslb.ca.gov.

It depends on the material. Steel corrodes sooner. Copper and plastic last longer. A camera or test tells us the state of yours.
