- Plumbers in Texas are licensed by the Texas State Board of Plumbing Examiners (TSBPE), and you can check a license online.

- Hays County, which includes San Marcos, had 4,397 insurance claims from the February 2021 winter storm.
What to do first
- Turn off the main water shutoff if water is spraying, pouring or spreading across the floor.
- If one fixture is leaking, close the small valve under that sink or toilet instead.
- Stop using sinks, toilets and the washer if drains are backing up.
- Turn off power to wet areas at the breaker if water is near outlets, but only from a dry floor.
- Take photos and video, then call to be connected with a local plumber who serves San Marcos.
When should you call a plumber in San Marcos right away?
Call a plumber in San Marcos right away when water is moving where it should not, when sewage is coming up, or when you have no water at all. These problems get worse by the hour and can damage floors, walls and cabinets quickly.
Treat these as urgent:
- A burst or split pipe, or water dripping from a ceiling
- A sound of running water when every tap is off
- Sewage coming up in a tub, shower or floor drain
- A water heater leaking from the tank itself
- No water anywhere in the house
For broken lines, the burst pipe repair page explains what that kind of repair usually involves.
How do you find and use the main water shutoff?
The main shutoff in most San Marcos homes is near where the water line enters the house, often in the garage, on an outside wall, or inside a closet near the water heater. There is also a valve at the meter by the street, usually under a small lid.
To use it:
- Turn a round wheel handle clockwise until it stops.
- Turn a lever handle so it sits across the pipe, not in line with it.
- Open a faucet at the lowest point in the house to drain pressure.
If the valve will not move or leaks when you turn it, do not force it. Tell the plumber when you call. Problems between the meter and the house are covered on the water line repair page.
What are the signs of a hidden leak in a San Marcos home?
Signs of a hidden leak include a water bill that jumps for no reason, a warm spot on a tile floor, a musty smell, or a meter that keeps moving when no water is in use. Hidden leaks often sit under a slab or inside a wall.
For a quick test, turn off all water, note the meter, and check again in an hour. If it moved, water is going somewhere. The leak detection page explains how plumbers find leaks without opening every wall.

Why are drains backing up in more than one fixture?
When several drains back up at once, such as a toilet and a tub, the clog is usually in the main sewer line, not a single fixture. Using more water will only push more back into the house.
Common causes include tree roots, grease, wipes and a sagging section of pipe. Stop using water, avoid chemical drain cleaners, and call to be connected with a local plumber. Single clogs are covered on the drain cleaning page.
What happens during the visit?
During the visit, the plumber inspects the problem, explains what they found and the options for fixing it, and gives you a written quote before any work starts. You decide what happens next.
- Inspection. The plumber looks at the leak, drain or fixture and may test pressure, run a camera down a drain, or check the shutoff.
- Options explained. You hear what a short-term repair looks like compared with a longer-term fix, and what each one involves.
- Written quote first. Ask for the scope of work in writing before you agree to anything.
How can you check a plumber's license in Texas?
You can check a plumber's license in Texas through the Texas State Board of Plumbing Examiners (TSBPE). Its consumer page suggests asking for the name of the company's Responsible Master Plumber and confirming the license is valid with a Certificate of Insurance on file.
Master Plumber license numbers begin with the letter M. TSBPE does not regulate what plumbers charge, so compare written quotes. It also suggests asking your city's plumbing inspection department whether a job needs a permit and inspection.

Plumbing in San Marcos and nearby towns
Weather shapes a lot of plumbing calls around San Marcos. From February 11-19, 2021, most of Texas had prolonged freezing temperatures, ice and power outages that caused damage from freezing pipes. Insurers reported 4,397 claims in Hays County from that storm, as of March 31, 2022, covering towns like San Marcos, Kyle and Buda.
Heavy rain matters too. The Lower Colorado River Authority says the Texas Hill Country is known as "Flash Flood Alley" because it has one of the greatest risks for flash floods in the United States. On October 30-31, 2013, 10-12+ inches of rain fell over central Hays County, flooding the Blanco River, San Marcos River and Onion Creek. Heavy rain can push water into sewer lines and cause backups.
The same advice applies across the area, from San Marcos to Kyle, Buda and Wimberley. See all service areas around San Marcos.
