Meter to House

Where Your Responsibility Begins

In most of Black Diamond the City provides water; around Lake Sawyer, Covington Water District does. Your service line runs from the meter to the house, and that stretch is the part we replace.

Before quoting anything we check pressure, flow and the interior piping. A pressure problem is not always the service line, and we tell you if the cause is somewhere else.

We also check for a pressure regulator problem or interior galvanized piping, which can mimic a failing service line. If the cause is inside the house, we quote that instead.

Signs the line is failing

  • →A soggy strip of yard near the line
  • →Pressure that dropped over time
  • →Brown water that does not clear
  • →A bill that rose without explanation
Old Core, New Neighborhoods

Different Ground, Different Plan

In the historic core, the line may be older and the lot more cramped, so we plan the route around existing structures and landscaping. In the newer subdivisions, the line is usually newer, and a leak is more often at a connection.

Either way, we call 811 for utility locates before any digging, and we mark our path with you.

Plan for a short interruption of water while the new line is connected. We tell you the timing in advance so you can fill containers and schedule around it.

The Work

Permit, Dig, Connect, Backfill

Plumbing permits go through the City of Black Diamond Permit Center, and we coordinate with the water provider for the meter connection. New lines are HDPE or PEX.

Basic backfill is part of the job. Sod, landscaping, concrete, asphalt and finish restoration are included only if listed in the written scope, so the price you approve is the price you pay.

Financing is available, and the estimate is free. We walk the route with you before the work starts so there are no surprises on where the trench goes.
