Signs of a Main Water-Line Problem
Soggy or Sunken Yard Spot
A patch of lawn that’s wet or sinking without recent rain often means water is escaping underground.
See leak detection →Low or Dropping Water Pressure
A steady drop throughout the house, not just at one fixture, can mean water is leaking out before it reaches your plumbing.
Unexplained Bill Increase
If your habits haven’t changed but the bill has climbed, a slow underground leak is one common cause.
Meter Still Spinning With Everything Off
If it’s still moving, water is flowing somewhere between the meter and your home, or beyond it.
Homeowner, Utility and Meter-Side Responsibility
Generally, the water utility owns and maintains the line up to the meter, and the property owner is responsible for the service line from the meter to the house. Eastern Municipal Water District (EMWD) serves much of Moreno Valley, though the exact provider can vary by address. We help you understand which side of the meter your issue is on before recommending a repair.
Spot Repair Versus Water-Line Replacement
Spot repair addresses a single break in an otherwise sound line — typically less disruptive and faster. Water-line replacement becomes the more practical option when a line is old, corroded, or has had repeated breaks. We’ll explain what we find and why we’re recommending one option for your specific line.
Trenching, Rerouting and Trenchless Options
Traditional trenching digs an open trench for direct access. Rerouting moves the new line to a different path when the existing route runs under a driveway. Pipe bursting pulls a new pipe through the path of the old one, reducing surface excavation. Common materials include copper, HDPE, and PVC.
Cost Factors
Length and depth, repair method, pipe material, site obstacles, permit requirements, and restoration needs all shape cost.
Permits & Utility Locating
Water-line work generally involves a permit through the City’s SimpliCITY portal. Before any digging, underground utility lines in the work area are located and marked.
Main Water-Line FAQs
How do I know if my main water line is leaking versus a smaller plumbing issue?
Look for whole-house signs: a soggy yard spot, dropping pressure throughout the home, a meter that keeps spinning with everything off, or a rising water bill.
Who is responsible for repairing the water line — me or the utility?
Generally, the utility is responsible up to the meter, and the homeowner is responsible from the meter to the house. We help confirm which side your issue falls on.
Do I need a permit to repair or replace my main water line?
Water-line work generally requires a permit through the City’s Building & Safety Division, processed through the SimpliCITY portal.
Will repairing my water line tear up my whole yard?
Not necessarily. Rerouting or trenchless methods like pipe bursting can reduce surface disturbance depending on your yard’s layout and the line’s condition.
What’s the difference between copper, HDPE, and PVC for a water line?
They differ in cost, flexibility, and durability. We recommend a material based on your property’s soil, line length, and budget.
What should I do if I have uncontrolled water or a suspected main-line break right now?
Locate your main shutoff valve and turn off the water supply if it’s safe. If you smell gas or see an electrical hazard near standing water, leave the area and contact the appropriate service first.
Uncontrolled Water or a Suspected Main-Line Break?
