Replacing the buried water line to Salem homes

In Salem, the city's responsibility for water generally ends at the meter, usually in a concrete box near the curb. The pipe from that meter to your house is a private line, and when it fails, the repair falls on the homeowner. Many older homes still have the original line, often galvanized steel that has rusted inside.

These lines fail in a few predictable ways. Some leak slowly underground for months, raising the bill and softening a strip of lawn. Others never leak but lose so much inside diameter to rust that the whole house runs weak. In both cases, replacing the line usually costs less over time than chasing repeat repairs.

Where the city's pipe ends and yours begins

Look for the meter box near the street, often in a parking strip or at the edge of the front yard. The city owns the meter and the pipe on the street side of it. From the outlet of the meter to the house, the pipe belongs to you, and so does any leak along it.

That private line is often longer than people expect, especially on deep lots or hillside homes set well back from the road. Before quoting, we walk the likely route, look for the main shutoff where the line enters, and note sidewalks, driveways and trees in the way.

Confirming the leak is in the buried line

We start with the meter. With every fixture off, a moving leak indicator says water is escaping. Closing the house shutoff tells us more: if the dial keeps turning with that valve closed, the leak sits between the meter and the foundation.

From there, ground microphones help us hear the leak through soil. Wet strips in the lawn, a sinking patch along the route or water bubbling up near the meter box during dry weather all support the finding. Once we know the line is the problem, we price both a spot repair and full replacement.

Trench or boring: getting the new line in the ground

Most new service lines go into an open trench dug along the old route or a straighter one. The trench has to reach enough depth to protect the pipe from frost and surface damage, and the line is bedded so rocks do not press against it.

Where the route crosses a driveway, walkway or mature tree roots, we can often bore beneath them and pull the new pipe through instead of cutting concrete. On most jobs the new line is a polyethylene or PEX water service pipe rated for burial, with copper used in some cases.

• Utility locates are called in before any digging
• Old pipe is abandoned in place or removed where the trench follows it
• New pipe is pressure tested before the trench is closed
• Lawn and soil are backfilled and leveled; sod or concrete repair is priced separately

What changes inside once the new line is in

A new service line restores the full flow your house can draw from the city main. On a home that had a choked galvanized line, the difference is usually obvious at every fixture. We install a new main shutoff where the line enters, so you have a valve that turns when you need it.

Higher flow can also expose weak spots that the old line was hiding, such as a pressure regulator that no longer holds or worn fixture valves. We check pressure at the house after the switch and tell you if anything downstream needs attention.
