From the first ring to a plumber at the door

Four steps, in the order they happen.

  1. Dial the number

    A person picks up, at any hour.

  2. Say where and what

    Give the street, the symptom and whether water is still running.

    The plumber explains the likely cause and what changes the cost before work starts.

Pricing

What moves the price of a plumber in Lakeway, TX

The same phone call can lead to a small repair or a large one. These are the reasons.

What is actually broken

A worn flapper and a failed buried line are different jobs, even when both show up as a wet floor.

Where the pipe runs

Open crawl space, wall cavity, slab or a slope in the yard each change the labor.

Parts and equipment

Tank size, valve type, pipe material and camera or jetting gear all enter the total.

Access on a hillside lot

Steep yards and tight side passages slow digging and carrying.

Have this ready for the call

  • Street and neighborhood
  • Where the water or smell is
  • When it began

Who runs what

Lakeway MUD handles the pipes, and the city does not

A district for both water and sewer

The City of Lakeway says on its own FAQ that it does not manage water or wastewater. Those jobs belong to Lakeway Municipal Utility District, usually shortened to LMUD. It supplies drinking water, collects and treats wastewater and distributes some recycled water. Its customers include most of Lakeway, part of the Village of The Hills and the Rough Hollow area. Since August 2026 it also covers the former Travis County MUDs serving Rough Hollow and The Highlands of Lakeway.

The practical point is that a plumbing question rarely belongs at city hall. A bill with the district’s name on it is the right starting document. Our page on the nearby plumber in The Hills explains the shared boundary.

Who to ask

What belongs to you

The district owns the mains and the meter. Your side starts at the meter for supply and at the cleanout or property line for the sewer lateral, though exact boundaries vary, so ask the district if a buried failure falls near the line. A leak that makes the meter dial spin with every fixture off is almost always on the house side. Our water line repair page explains how that pipe fails, and the main valve guide shows where to stop it.

Meter test
  • Find the meter boxIt usually sits near the street or driveway edge.
  • Close the house valveStops water without touching the district’s equipment.
  • Read the meterA moving dial with everything off means a hidden leak.
  • Call and report the readingIt saves a diagnostic step.
A first check before the phone call.
What comes out of the tap

Lake Travis water, mineral scale and flushing the line

A surface supply with a reported pH

LMUD says its drinking water is drawn from Lake Travis. The 2025 annual report lists a pH of 7.8, which is mildly alkaline and not corrosive on its face. The report also advises running a tap for 30 seconds to 2 minutes when water has sat in the house for several hours. That is useful advice after a weekend away or a night with the house closed up, since the first draw has spent time in your own pipes.

If the water keeps tasting metallic or looks discolored after flushing, call and describe it. It can point to an old fixture, a tired supply pipe or a water heater problem. See signs of corroded pipes for what to compare.

Report snapshot

Hardness: ask for the figure at your address

The district’s own report does not give a hardness number for the tap. One third-party listing puts Lakeway MUD water near 9 grains per gallon, which sits in the moderately hard to hard band. Treat that as a rough guide and ask the district for a current figure for your street. Scale announces itself anyway: crust at the spout, a clouded glass shower door, a rumbling tank. A water softener addresses the whole house, while water filtration addresses taste and particles at the tap.

From crust to a fix
  1. Spot the scale

    Look at faucet tips, kettles and the shower door.

  2. Ask the district

    Request a current hardness figure for your address.

  3. Check the heater

    A tank full of sediment loses capacity and gets noisy.

  4. Choose treatment

    Whole house for scale, tap-level for taste.

Four moves, in order.
Sewer behavior

Homes below the street and the backup risk

Why some Lakeway houses are exposed

LMUD has said some homes sit below grade, meaning lower than the sewer main in the street. When the main surcharges or a blockage downstream builds pressure, the lowest opening in the house is where wastewater arrives. That is a basement-level floor drain, a lower bath or a garage sink. The district is installing backflow relief valves at homes where it can, to give that sewage somewhere to stop.

If you see water rise in a tub while the washing machine drains, stop the machine. A sewer camera inspection finds out whether the blockage is in your lateral or the district’s main. Do not pour chemical drain openers into a backing line.

How the clues widen as the problem grows.
Backup clues

Roots, grease and what you can do

A clog that returns every few months usually has a pattern behind it: grease in a kitchen run, a root intrusion at a joint, or a sag that holds water. Hydro jetting scours a line wall clean, and sewer line repair replaces a damaged section after the camera locates it. The unclog a drain guide covers safe steps for a single fixture.

Yards and reuse

Recycled water, sprinklers and a hilltop lot

Where treated wastewater goes

LMUD treats wastewater at the Palos Verdes Water Recycling Plant and sells the recycled water for irrigation, including golf courses and about 25 other customers. The district says none of it is returned to Lake Travis. For a homeowner, the lesson is that recycled water lines are a separate network. Never connect one to indoor plumbing. If your lot has any irrigation, a backflow testing visit confirms the device keeps yard water out of the drinking supply.

Watering rules and lake levels

The district’s site refers to local watering restrictions tied to the levels of Lake Travis and Lake Buchanan. Rules change, so read the current notice before programming a controller. A zone that runs when it should not, or a patch that stays soggy long after a cycle, often means a cracked line or a valve that fails to close. The leak detection page covers the meter test that separates a yard leak from a house leak.

Sprinkler check
  1. Shut the zone

    Turn off the controller for the suspect zone.

  2. Watch the meter

    If the dial still moves, the leak is not the sprinkler.

  3. Walk the yard

    Look for pooling, geysers or a sunken patch.

  4. Call with notes

    Describe the zone and what you saw.

Owner-occupied houses on slopes and lake lots

A mostly owner-occupied town

Census figures show 86.3 percent of Lakeway homes are owner-occupied, and the 2020 count lists 8,314 housing units with about 9 percent vacant. About 16 miles west of Austin at roughly 830 feet, the town sits beside Lake Travis with Hurst Creek running through it. Owners tend to be the ones on the line, which means decisions about a water heater replacement or a repiping job are made by the person at home.

Vacant units matter too. A house left empty for weeks can leak unseen. Shutting the main before a long trip and running taps on return are small steps that spare a repair. The how to find a water leak guide lists the checks.

Questions

Questions from Lakeway homeowners

Who supplies water and sewer service to Lakeway homes?
Lakeway MUD handles water and wastewater in most of the town, not the city. Some addresses are served by other districts, so read the name on your latest bill. A call to us can start with the street and we will work from there.
How do I find a plumber in Lakeway, TX at night?
Dial the number on this page. A person answers around the clock. Give your street, say what is happening and whether water is still running, and the next step gets set from there.
Is Lakeway water hard?
The district’s report gives no hardness figure. A third-party listing suggests around 9 grains per gallon, which is moderately hard to hard. Ask LMUD for a current number for your address. Scale on faucets and a noisy tank heater are the signs.
Why does water taste flat or metallic after I come home from a trip?
Water that sat in household pipes for hours can pick up a taste. The district advises running a tap 30 seconds to 2 minutes first. If the taste stays, call and describe it.
What does a sewer backup in a low drain mean?
Often it means a restriction in the lateral or main. LMUD has noted some homes sit below grade, which raises backup risk. Stop using water, stay clear of the spill and call for a camera inspection.
How much does a plumber cost in Lakeway?
It depends on the kind of fix, how reachable the pipe is, which parts it needs and what the first look finds. A flapper swap and a buried line repair sit far apart. Ask about pricing when you call.
Why do two similar jobs get different totals?
Access, materials and root cause drive the difference. A slow drain from hair is a short visit, while the same symptom from a cracked pipe is not. The plumber explains the factors on site.
Can I get same-day plumbing service in Lakeway?
Same-day service is available. Active leaks and sewage come first. Tell us how urgent the situation is when you call and we will say what can be done today.
My ceiling is dripping. What do I do first?
Shut off the main valve, move valuables, and switch off power to wet areas only if you can do it without standing in water. Then call. The burst pipe guide has the full sequence.
Can I connect my sprinkler to recycled water myself?
Recycled water is a separate network used for irrigation. Never tie it to indoor plumbing. Ask the district what is offered on your street and have a backflow device checked.
Do you have an office in Lakeway?
No. We cover Lakeway, and calls from there are taken on the same number we use for the whole region.
Where do I look up watering restrictions?
The district posts them, and they change with the levels of Lake Travis and Lake Buchanan. Check its site before you program a timer. A zone that floods outside the rules is worth a leak check.
