24/7 Emergency Plumber in Houston TX: What to Do When Pipes Burst or Drains Back Up

Plumbing emergencies don't follow business hours. A pipe burst during a Sunday morning setup. A sewage backup on a Friday night at 9pm. A grease trap overflow 45 minutes before your lunch rush begins. These events happen — and when they do, the difference between a $600 fix and a $15,000 disaster is often how fast a licensed plumber arrives.

MKMaintX's Houston plumbing team dispatches 24 hours a day, 7 days a week, 365 days a year. Here's exactly what to do from the moment a plumbing emergency strikes.

The 5 Most Common Commercial Plumbing Emergencies in Houston

1. Pipe Burst (Especially During Freeze Events)

Houston's periodic hard freezes catch businesses completely off guard. February 2021's Winter Storm Uri produced the largest commercial pipe burst event in Houston history — thousands of businesses experienced simultaneous pipe failures because Houston's commercial buildings are simply not insulated for sustained 10°F temperatures.

What to do:

1. Immediately locate and close your building's main water shutoff valve
2. Open all faucets to relieve pressure and allow remaining water to drain
3. Call MKMaintX: 1-800-669-5808 — we dispatch within 2 hours
4. Document the damage with photos before any cleanup begins (for insurance)
5. Do NOT turn heat back on in the affected area until the burst section is repaired (refreezing causes additional damage)

2. Sewage Backup

A sewage backup — floor drains pushing wastewater back up into the kitchen or restroom — is both a health hazard and an immediate health code violation. Houston HDFCS inspectors treat active sewage backup as a mandatory closure trigger.

What to do:

1. Stop all water use in the building — flushing toilets, running sinks, dishwashers
2. Clear all personnel from the affected area
3. Call MKMaintX: 1-800-669-5808
4. Do NOT attempt to use chemicals or a plunger on sewage backup — it can worsen the situation and expose staff to pathogens
5. If the restaurant is open, suspend kitchen service in the affected area until cleared

3. Grease Trap Overflow

A grease trap that has exceeded capacity will begin pushing grease-laden water back through kitchen floor drains. Houston HGSD regulations make grease discharge to the sewer system a serious violation.

What to do:

1. Stop all kitchen drain activity
2. Call MKMaintX: 1-800-669-5808 and your grease trap pumping company simultaneously
3. Do not use chemical drain cleaners — they kill trap bacteria and worsen the problem
4. Begin dry cleanup with absorbent pads to prevent spread
5. Document the overflow before cleanup (critical for self-reporting to HGSD)

4. Water Leak (Active)

A visible water leak inside a Houston commercial building — whether from a supply line, fitting failure, or corroded pipe — needs to be stopped immediately to prevent structural damage, mold growth, and electrical hazards.

What to do:

1. Close the supply valve for the affected line (or main shutoff if you can't isolate)
2. If water is near electrical panels or outlets, cut power to that circuit first
3. Call MKMaintX: 1-800-669-5808
4. Begin water extraction with mops/wet-vac to minimize floor damage
5. If drywall or ceiling tiles are saturated, document before they're disturbed

5. No Hot Water

A commercial water heater failure during operating hours shuts down dishwashing, handwashing stations, and food prep. Houston health code requires specific minimum water temperatures at food service sinks.

What to do:

1. Check the water heater's pilot light or circuit breaker first (simple fix)
2. If the unit is making unusual sounds or leaking, shut off the gas/electric supply
3. Call MKMaintX: 1-800-669-5808 — we carry common commercial water heater units on our service vehicles for same-day replacement
