Your water service line is the pipe that carries water from the curb shut-off into your house. When it leaks, cracks or corrodes through, you may see a wet lawn, a meter that runs with everything off, or a sudden drop in pressure.
Water line repair in Randolph, NJ means locating the failure, then repairing or replacing the damaged length. Because the owner is responsible for this pipe, the repair decision is yours, and we explain the options plainly before work starts.
Water service line leaks and replacement
Randolph homeowners own the water service pipe from the curb shut-off to the house. That means a leak on that stretch is not something the township fixes for you. The Division of Water and Sewer can confirm your meter reading, and then the repair is a plumbing job.
Signs of a failing line include a soft or sunken area in the yard, water at the meter box, discolored water and pressure that drops without a reason inside the house. A buried leak does not always surface, so a meter that moves when the house is idle is often the first clue. Our leak detection methods pinpoint the break so only that spot is dug up.
Patch the break or replace the line?
| Choice | Best when | Watch for |
|---|---|---|
| Spot repair | One clear break in otherwise sound pipe | Other weak spots may fail later |
| Partial replacement | A section is corroded or damaged by a root or a shift | New and old pipe meet at a connection that must be done right |
| Full line replacement | The pipe leaks in several places or is near the end of its life | More digging and a higher upfront price, but one lasting fix |
| Trenchless replacement | Landscaping or pavement is in the way | Depends on soil, depth and the existing pipe, so it is not always possible |
We tell you what the dug-up pipe looks like before you commit. If the line is in good shape except for one spot, a spot repair is the honest answer.
Before the plumber arrives
A failed service line can drain water out of the house or flood a yard. These steps keep it manageable.
1Close the house main
Shut the valve inside where the line enters. If water still flows at the meter box outside, tell the dispatcher.
2Keep people off soft ground
A washed-out area around the pipe can collapse. Keep children and pets back from the wet spot.
3Photograph the meter
A picture of the dial helps show whether the leak is before or after the house valve.
4Store some water
Fill a few containers for drinking and flushing before the supply is cut for the repair.
Low water pressure: where to look
Weak pressure has a few common causes. We sort them by whether it affects the whole house or just one fixture, because the answer changes the fix.
- One faucet or showerhead only: a clogged aerator, cartridge or stop valve at that fixture.
- Hot water only: sediment in the water heater or a partly closed valve on the hot side.
- Whole house, gradually worse: corrosion narrowing the pipe or a pressure regulator wearing out.
- Whole house, suddenly: a leak on the service line, a partly closed main valve or a problem with the supply itself.
We check pressure with a gauge at an outdoor hose bib, then work toward the fixture that is acting up. If the gauge reads normal at the hose bib, the problem is inside the house and a pipe change like repiping may be the fix.
Is your home on township water or a private well?
Not every Randolph home gets the same water. The township's distribution system also serves parts of Mendham and Chester, a northern section is served by the Town of Dover, and the rest of the township is on private wells. Which one applies to you decides who you call first.
| Source | Where the utility stops | First call |
|---|---|---|
| Township system | At the curb shut-off | Division of Water and Sewer for the meter, a plumber for your side |
| Town of Dover service | Ask that utility where its side ends | Dover's utility for the meter, then a plumber for your side |
| Private well | You own the whole system | A plumber for the pipe and pump, a certified lab for water testing |
If you are unsure, ask the township water division before you dig. A well owner has no municipal meter to check, so a plumber's pressure test is the starting point.
A wet spot near the meter box
Water pooling around the meter box often means a fitting has failed on your side of the meter. Left alone, the leak washes soil away and grows. We check the connections at the box, test the line and repair what is ours to repair.
If the leak is clearly ahead of the meter on the utility side, we will tell you so and help you describe it to the township.
Randolph's water source and what it means for your line
Randolph buys wholesale water from the Morris County Municipal Utilities Authority, which pumps groundwater from eight wells, six in Randolph and Chester and two in Flanders Valley. The township owns no source or treatment plant. So if something is wrong between the curb and your tap, the cause sits in the pipe, not at a plant.
Township testing found a lead 90th percentile of 0.0033 mg/L across 30 samples in 2023, against an action level of 0.015 mg/L.
Copper came in at 0.127 mg/L against an action level of 1.3 mg/L. Both are below the action levels. Those figures describe the system, though, and an older service line or fixture inside a home is a separate question. If we replace your line, we tell you what it was made of.
Softeners, filters and treating your water
Before buying a softener or filter, find out what you are treating. Randolph's published water tables do not report hardness, pH or alkalinity, so we will not guess a number for your tap. You can ask the water division, or test the water at your own faucet.
A plumber installs the equipment and its connections, while a certified lab tests water from a private well. If your concern is rust-colored water or low flow, the pipe may be the cause and a filter would only hide it.
When a water line leak becomes an emergency
Call right now if water is surfacing in the yard, the basement is taking on water, or the house has no water at all. Check whether neighbors are affected too. An April 2024 main break in Randolph led to a boil water advisory, and a street problem can look like a failed service line.
Also rule out a toilet, since the township notes a running one can waste up to 200 gallons a day or more and look like a leak.
If a leak on this line has already damaged pipe inside, our plumbing installation work handles the new connections, and we serve Roxbury and nearby towns on the same dispatch.
Water line repair pricing, in plain terms
A service line job is quoted after we find the failure. You see the price before the digging starts.
A short, shallow run is a smaller job than a long, deep one.
Lawn costs less to restore than a driveway, walkway or patio.
A single break is a spot fix. A tired line may be replaced entirely.
Open trench or trenchless, depending on soil and the existing pipe.
Some work needs approval from the township. Ask the township construction office whether yours does.
Many home policies exclude the buried service line or cover it only through an optional add-on. Check your policy for service line or exterior pipe wording, because coverage differs a lot between insurers.
Call the 24/7 line and ask how the price is built for your property.
Call (908) 357-1542Water line and low pressure FAQ
The homeowner. In Randolph, owners are responsible for the water service from the curb shut-off to the house.
A clogged fixture, a worn pressure regulator, corroded pipe or a leak on the service line. Checking whether one fixture or the whole house is affected is the quickest way to narrow it down.
Yes. Our 24/7 line is answered nights, weekends and holidays. Shut the main valve inside the house if you can reach it.
Depth, length, surface restoration, pipe condition and the repair method all play a part. We provide a clear price before work starts.
Watch for a meter that runs with everything off, a soggy lawn patch, a high bill or low pressure. A plumber confirms with a pressure test and listening equipment.
Township testing in 2023 showed lead below the action level. That result is for the system. An older service line or fixture inside a home is a separate question, and we can check what your line is made of when we work on it.
The township tables do not list hardness, so test your own tap or ask the water division before you buy equipment. A plumber can install what you choose.
No water, low pressure or a soggy yard? Call the 24/7 line and tell us what you are seeing.
