Emergency Plumbing in DeSoto, TX
If water is running and you cannot stop it, do this before you keep reading.
Shut off the water. Most homes have a main shutoff where the supply line enters the house, often in the garage or on an exterior wall facing the street. For one fixture, the stop valve is under the sink or behind the toilet.
If you smell gas, leave the building first with everyone in it, including pets. Do not flip switches or use your phone inside. Once you are outside and away, call 911. Then call Atmos Energy at 866-322-8667. Atmos is the gas utility for DeSoto and will make the line safe. Call us at 214-918-6109 for the repair once the area has been cleared.
For everything else, call 214-918-6109.

What to Do in the Next 30 Minutes
The first half hour decides how much damage a leak does. Here is what limits it, in order.
Stop the water
Main shutoff for a burst line, fixture stop for one leak, the cold water valve at the top of the tank for a leaking water heater.
Kill the power where water is
If water is near outlets, a ceiling light or an electric water heater, turn off that breaker. If you cannot reach the panel without standing in water, do not.
Open the faucets
Once the main is closed, open a tap at the lowest point in the house to drain what is left in the lines.
Stop using drains if sewage is coming up
No toilets, sinks, washer or dishwasher. Every gallon you send down comes back up.
Photograph everything before you clean, and keep every receipt
Your insurance carrier will ask, and the city tells residents with a sewer backup to save all receipts for repair, cleaning and damage.
Move what you can
Rugs, electronics and anything cardboard, out of the water and away from the ceiling below a leak.
Sewage Backing Up? In DeSoto, the First Question Is Your Cleanout.
The City of DeSoto runs its own sewer maintenance crew, with an after-hours number: 972-780-6641. In business hours, Monday to Friday 8 am to 5 pm, the number is 972-230-5724.
The first thing the city’s emergency crew will ask is where your cleanout is. A cleanout is a capped pipe, usually about 4 inches across, that rises from your sewer line to just above the ground near the house, most often in the front yard.
Meet James Armstrong
Meet the Master Plumber Serving DeSoto: James Armstrong
James Armstrong has been a Mesquite-resident Master Plumber since 1995. What began as helping neighbors fix leaky faucets turned into a career — and eventually a family business, built on one simple rule: treat people right, do the job with integrity, and always stand behind your work. Today, James and his crew serve DeSoto, Sachse, Garland, and the broader DFW metro from the Mesquite headquarters at 844 Dalworth Dr.
“In thirty years of plumbing across the DFW metro, including DeSoto, the drain calls almost always come down to two things: tree roots in the older neighborhoods, and grease and hair buildup in the newer developments. We camera-inspect first, then choose hydro-jetting or snaking based on what we actually see — not on what gets you to the highest invoice.”

What Counts as an Emergency, and What Can Wait
In DeSoto, some emergencies belong to the city and some belong to you. The City of DeSoto takes water and sewer calls at 972-230-5724, Monday to Friday 8 am to 5 pm, and at 972-780-6641 after hours and on weekends.
| What you see | Who to call first | What happens next |
|---|---|---|
| Water coming up in the street | City of DeSoto | Usually a city main. A plumber cannot repair it. The city says a main break usually takes three to six hours to repair |
| Low or no pressure across the whole street | City of DeSoto | Check with the city before you pay anyone to come out. If a main is down, nothing is wrong inside your house |
| Sewage backing up, and you have an accessible cleanout | City of DeSoto | The crew can tell whether the blockage is in your line or the city’s line, and break it if it is in the city’s line |
| Sewage backing up, and there is no cleanout or nobody can find it | A plumber | The city says you will need to call a plumber. The cleanout is the property owner’s responsibility |
| Low pressure in your house only, plus a wet patch in the yard | A plumber | Usually the line between the meter and the house. That repair is yours |
| A leak under the slab, in a wall or in the underground service line | A plumber, then the city billing office | Ask the city for a leak adjustment within 20 days of finding the leak, with a receipt showing the date and location of the repair |
Find your cleanout today, while nothing is wrong. If it is buried, a registered plumber can locate it and raise it to grade.
If you smell gas, none of this applies. Leave the house and call 911 from outside first.
