Why should I think about water line repair in Austin before winter?
Fall is a good time for water line repair in Austin because a weak or leaking line is easier to fix on a calm, dry day than during a freeze, when many households need help at once. A small leak you notice in October can turn into a bigger break once cold nights and shifting soil add stress to the pipe.
The main water line, also called the service line, runs underground from the water meter to your house. Our main water line repair page covers the general service. This page focuses on getting the line ready before freeze season.
What are the signs my main water line is leaking?
The most common signs of a leaking main water line are a wet or extra-green strip of yard between the meter and the house, a water bill that keeps rising, lower pressure at every fixture at once, and a meter that moves when nothing in the house is running.
- A soft, muddy spot in the yard that stays wet during dry weather
- Water pooling near the meter box or along a driveway or walkway seam
- Taps that sputter air or run cloudy after the water has been off
If you are not sure where the water is going, leak detection is often the first step before anyone digs.
How can I check my water meter for a hidden leak?
You can check for a hidden leak by turning off every faucet, appliance and sprinkler, then watching the water meter for 15 to 30 minutes. If the meter or its small leak indicator moves while nothing is using water, water is escaping somewhere.
Next, close the shutoff valve where the line enters the house, if you have one, and look at the meter again. If it still moves, the leak may be on the buried line between the meter and the house. If it stops, the leak is more likely inside, such as a running toilet or a slab leak.

Can a freeze damage an underground water line in Austin?
Yes, a hard freeze can stress parts of a water line in Austin, especially exposed sections. The pipe near the meter box, where the line rises out of the ground, and any pipe running along an outside wall are the most exposed. Water expands when it freezes, which can split a weak pipe or fitting.
Lines that are already corroded, cracked or leaking at a joint are more likely to fail when cold weather arrives. Soil movement adds stress too. Parts of the Austin area sit on expansive clay soil that shrinks when dry and swells when wet, which can pull on older pipe over time. If a pipe has already split, see burst pipe repair.
Where is my water shutoff valve, and why does it matter before a freeze?
For most Austin homes, the owner's shutoff valve is in the meter box near the street, on the owner's side of the water meter. Knowing where it is matters because closing it quickly limits damage if a line breaks.
Find it before the weather turns. Open the meter box lid carefully, look for the valve on the house side of the meter, and make sure you can turn it. Austin Water notes that the City valve in the meter box may need a meter key, which most hardware stores sell. Many homes also have a second shutoff where the line enters the house. Our guide on what to do when a pipe bursts walks through the steps if water is already spraying.
Should I repair or replace my main water line?
Whether to repair or replace a main water line depends on the age, material and condition of the pipe. A single break in otherwise sound pipe can often be repaired at that spot. A line with corrosion or repeat leaks along its length is usually a better fit for replacement.
Ask the provider to explain what they found and why they suggest one option over the other. Good questions include:
- Is the problem in one spot or along the whole line?
- Would an open trench or a trenchless method work on this route?
- What will be disturbed, such as lawn, driveway, sprinklers or tree roots?
What happens during the visit?
During the visit, the provider inspects the line, confirms where the leak is, explains your repair options, and gives you a written quote before any work begins. You decide whether to move forward.
- Inspection: The provider checks the meter, the shutoff valve and the yard, and may test the line to separate a service line leak from an indoor leak or a sprinkler problem.
- Options explained: They walk through a spot repair, a partial replacement or a full replacement, and what each one involves for your yard and driveway.
- Written quote: You get the scope of work in writing before any digging starts.
Timing depends on the provider's schedule, the weather and permit rules in your city.
Who is responsible for the water line, me or the city?
In most cases the water utility is responsible for the pipe up to and including the meter, and the property owner is responsible for the service line from the meter to the house. Confirm this with your own water provider, because rules can differ.
That matters across the Austin area. Round Rock, Pflugerville, Cedar Park, Georgetown and other nearby cities run their own water utilities separate from Austin Water, so call the utility listed on your bill if you are unsure where your side begins. If the leak turns out to be under your foundation instead of in the yard, read about slab leak repair.
How does Austin weather affect water lines in winter?
Austin does not freeze often, but when it does, water lines can take a hit. The National Weather Service reports that over 1991-2020, Austin's average first freeze at Camp Mabry was December 1 and the average last freeze was February 15. Freeze risk is not the same across town: sub-freezing temperatures happen about 12 days a year on average at Camp Mabry but about 33 days at Austin-Bergstrom Airport, where clear winter nights can be up to 10 degrees colder.
The February 2021 winter storm showed what can happen. Austin Water issued a citywide boil water notice on February 17, 2021, after so much water was lost to dripping faucets and broken pipes that storage fell well below its minimum. As of March 31, 2022, insurers reported 31,823 claims in Travis County and 14,439 in Williamson County from that storm.
The Texas Department of Insurance warns that home policies might not pay for frozen pipe damage if you did not take steps to protect your pipes, and it says to turn off the water at the shutoff valve if pipes freeze. Whether you live in central Austin, Round Rock, Pflugerville, Cedar Park or Buda, fall is the time to find your shutoff and get a suspect line checked.
When you choose a provider, the Texas State Board of Plumbing Examiners suggests asking for the name of the company's Responsible Master Plumber and checking that the license is valid. TSBPE also advises asking your city's plumbing inspection department whether a job needs a permit.

Questions people ask
How do I know if I need water line repair in Austin?
You may need water line repair if you see a wet spot in the yard, a rising water bill, low pressure at every tap, or a meter that moves when no water is in use. Call to be connected with a local provider in Austin who can inspect the line and confirm the cause.
Is it better to fix a leaking water line before winter in Texas?
Yes, it is usually easier to fix a known leak before winter. A weak line is more likely to fail during a freeze, and repairs can be harder to schedule when many homes have problems at the same time.
Can a small water line leak in my yard get worse in cold weather?
It can. Freezing and thawing, plus soil movement, can put more stress on a pipe that is already leaking or corroded. A small leak also keeps the soil wet, which can make the problem spread.
What does it mean if my water meter is spinning with everything off?
It usually means water is leaking somewhere. Close the house shutoff and watch the meter again. If it still moves, the leak may be on the buried service line between the meter and the house.
Who pays for a broken water line between the meter and my house in Austin?
In most cases the property owner is responsible for the line from the meter to the house, and the utility handles its side of the meter. Check with your water provider, because each utility sets its own rules.
Will homeowners insurance cover a broken main water line?
It depends on your policy. Many policies treat sudden damage differently from gradual leaks, and coverage for the pipe itself may differ from coverage for water damage. Check your policy, take photos and document everything.
Where is the water shutoff valve on most Austin homes?
On most Austin homes, the owner's shutoff valve is in the meter box near the street, on the owner's side of the meter. Some homes also have a second shutoff where the line enters the house.
Should I drip my faucets when a freeze is coming in Austin?
Austin Water suggests dripping faucets during one to two days of freezing weather. It also suggests keeping the thermostat at 65 degrees or higher if you will be away during a freeze.
Can I repair my own water line in Texas?
Texas law lets a property owner do plumbing work on their own homestead without a plumbing license. Your city may still require a permit, so check with the local plumbing inspection department first.
Does water line repair need a permit in Austin?
Many water line jobs need a permit, but rules vary by city. The Texas State Board of Plumbing Examiners advises asking your city's plumbing inspection department whether your job needs a permit and inspection.
What is the difference between trenchless and traditional water line replacement?
Traditional replacement digs a trench along the whole line. Trenchless methods work from small pits at each end and pull new pipe through, which can spare lawns and driveways when the ground and route allow it.
How can I check if a plumber is licensed in Texas?
You can look up plumbing licenses through the Texas State Board of Plumbing Examiners. TSBPE suggests asking for the company's Responsible Master Plumber and notes that Master Plumber license numbers begin with the letter M.
What should I do if my water line breaks during a freeze?
Turn off the water at the shutoff valve right away to limit damage, then call for help. Take photos of any damage and keep notes for your records and any insurance claim.
What questions should I ask before agreeing to water line repair?
Ask what caused the leak, whether a spot repair or replacement fits, what will be dug up, who handles the permit, and who restores the yard or driveway. Ask for all of it in a written quote before work starts.
Does Round Rock or Cedar Park use Austin Water?
No. Round Rock, Cedar Park, Pflugerville, Georgetown and other nearby cities run separate water utilities. Contact the utility listed on your bill for questions about the meter or the utility side of the line.
