The pipe that feeds the property

Water line repair for homes and businesses

The water line carries supply from the meter into the building, so a leak there can affect every fixture. Trident Plumbing & Drain repairs water lines for homes and businesses, starting with an assessment of where the line is damaged and the condition of the pipe around it.

Our North Phoenix office arranges water line visits. This service is different from a leak beneath the foundation, which our slab leak repair page covers, and from tracing an unknown leak, which starts with leak detection.

What changed

Signs the supply line may be leaking

Wet areas or standing water in the yard or along a driveway, a bill that rises without explanation, lower pressure at several fixtures and unexplained discoloration are all reasons to look at the water line. Note whether the change affects one fixture or the whole property.

Describe where outdoor wet spots appear, when they started and whether they return after drying. These symptoms help frame the request, but they do not confirm the exact source or the repair needed. Earlier leak or pipe repairs are useful history.

City side or yours

Where the city's responsibility ends

For City of Phoenix water customers, the city's guidance on service issues states that problems from the street to the water meter are the city's responsibility and issues after the meter are the homeowner's. A leak on the street side of the meter is one to report to the city.

From the meter to the building and through the property, the supply piping is the part Trident inspects and repairs. If you are not sure which side a wet area is on, describe its location; the answer decides who should look at it first.

A single damaged spot on an otherwise sound line may be repairable. A history of leaks, corrosion or wider damage shifts the conversation toward replacement. Neither answer is automatic, so the recommendation should follow what the assessment found.

After locating the damage, Trident explains the options and provides an estimate for the proposed work. If a new line is proposed, ask what makes the bigger job necessary and what a repair of the damaged section would leave unresolved.

Plan the work

Access, digging and an active leak

Method, access and timing depend on where the line runs and the extent of the damage. Ask about the work area and any excavation or restoration involved. Not every line can be reached without digging, and a completion time cannot be fixed before the inspection.

If water is actively escaping, close the main shutoff only if you know where it is and can reach it safely, then tell the office whether the supply is off and the leak is continuing. A leak that is spreading fast should be treated as an emergency.

Check the inventory

Look up your service line before paying to replace it

Before you pay to replace the pipe between the meter and the house, look it up. Under federal lead and copper rules, the City of Phoenix has published an inventory of water service line materials, and it says it has found no lead lines since its field investigations began in 2021. When the City identifies a customer's line as galvanized, it contacts the customer with next steps, and it covers the entire cost of the replacement it schedules, from the meter box to the connection at the house.

If your line is copper or plastic, or the damage is a single leak, the repair is a private job on your side of the meter. Low pressure has simpler causes worth ruling out first. The City lists four inside a property: mineral deposits in galvanized plumbing, a softener that needs maintenance, a partly closed house valve and debris in faucet aerators. Checking those before digging keeps a small fix from turning into a trench.

Line repair pricing

Pricing a supply line repair

Most of the cost of a water line repair is in reaching the pipe.

For a full line replacement, GreenSky® financing is available.

  • Whether the City's inventory flags the line as galvanized.
  • The length of the run from the meter to the house.
  • Depth, and what sits above the line: lawn, rock, pavers or concrete.
  • A section repair or a new line.
  • Replacing the house valve or a pressure regulator at the same time.

Ask our team
Is the pipe between the meter and my house my responsibility?

If the city supplies your water, its guidance places issues after the meter with the property owner. That stretch of supply line is the kind of work Trident inspects and repairs.

Will my yard need to be dug up?

Access depends on where the damaged section is and how it can be repaired. The method and any excavation or restoration are explained after the inspection.

Does one leak mean the whole line needs replacing?

No. A localized fault may be repairable. Repeated failures or wider corrosion are what can prompt a replacement discussion.

Can low pressure point to a water line problem?

It can, especially if pressure has dropped at several fixtures at once. Pressure changes have other causes too, so the line is assessed before a repair is recommended.

Will the City replace my galvanized water service line?

If the City identifies your service line as galvanized, it says it will contact you with next steps, and it covers the entire cost of the replacement it schedules, from the meter box to the connection at the house. Check the City's service line inventory map for what is on record for your address.

Why is my water pressure lower in the morning?

The City says pressure varies with demand, and households getting ready for work and school can lower pressure in the early morning. If pressure is low all day at every fixture, have the supply line and house valve checked.
