Water line replacement and repiping swaps an old service line for a new one, from the street connection to the house. It is the answer when repair stops making sense: a line that has leaked more than once, a pipe corroded through along its length, or a lead line that should not stay in the ground. A new line ends the cycle of repeat leaks and restores full water pressure.
The pipe used for replacement is modern copper or PEX — the two standard materials for service lines today. Copper is rigid, long-proven, and familiar in older homes. PEX is flexible, resists scale buildup, and handles ground movement well. Which one fits depends on the soil, the length of the run, the existing setup, and the cost factors for your property. Your provider will explain the options before the work begins.
What water line replacement & repiping includes
- A full assessment of the existing line before any work is agreed
- New pipe from the street connection to the house
- New fittings and a shutoff valve where the line enters the house
- Lead line replacement where a lead service line is found
- Trench backfilled and the surface left tidy after testing
How it works
Call (740) 334-4561 and describe the line's history — repeat leaks, low pressure, its age. We connect you with a local Lancaster provider.
The provider checks the line's material, condition, and route, and explains whether repair or replacement fits.
The old line is removed and new pipe is laid along the route, with new fittings and a shutoff valve.
The new line is pressure-tested, the trench is backfilled, and the findings are explained.
Water Line Replacement & Repiping in Lancaster
Lancaster is a strong candidate for replacement work because so much of its housing stock predates 1970, when galvanized and lead service lines were common. Those lines are now past the age where corrosion is a question — it is a matter of how far it has gone. Ohio law helps here: under Ohio Revised Code 4909.174, in effect since March 20, 2026, water-works companies must reimburse customers who replace a customer-owned lead service line, when the line is confirmed as lead or ordered replaced and the request is made within twelve months of completion.
Copper or PEX?
Copper has been the standard service-line material for generations. It is rigid and durable, it handles heat well, and it is the pipe most older Lancaster homes already have inside. Its main weakness is corrosion in aggressive soil and water, which is exactly what wears out old galvanized lines.
PEX is a flexible plastic pipe that has become standard for new work. It resists scale and corrosion, it bends around obstacles without joints, and it tolerates ground movement — useful in central Ohio clay soils that swell and shrink. Either material, installed well, will outlast the line it replaces. Your provider will recommend the one that fits your soil, your run, and your home.

Water Line Replacement & Repiping questions, answered
When does a line need replacing instead of repair?
When it has leaked more than once, when corrosion runs through its length, when the pipe is lead, or when internal buildup has cut the water pressure. A single split in an otherwise sound line is a repair; a line that keeps failing is a replacement.
What pipe is used for replacement?
Modern copper or PEX, matched to the home, the soil, and the length of the run. Your provider will explain the two options and recommend the one that fits your property.
How long does replacement take?
It depends on the length of the line, its depth, the soil, and access to the route. Your provider will explain the expected scope after the assessment.
Will replacement fix low water pressure?
If the cause is internal corrosion or a failing line, yes. If the cause is elsewhere — the municipal supply, a fixture, or a valve — the assessment will show that before any work is agreed.
Is there help with the cost of replacing a lead line?
Under Ohio Revised Code 4909.174, water-works companies reimburse customers who replace a confirmed lead customer-owned line when the request is made within twelve months of completion. Ask your provider about it before the work begins.
