Emergency Plumbing Services In San Marcos

Life in San Marcos has a way of keeping you on your toes. Even in the most well-kept homes, things can go wrong beneath the surface. A leaking gas line, cracked pipe or sewage backup can quickly shift from inconvenience to emergency.

That’s why it’s important to stay vigilant, understand the signs of a plumbing emergency and know when to call for professional help. At Oasis Plumbing, Heating & Air Conditioning, we’re here to guide you through urgent situations, offer expert solutions, and help you take smart action when it matters most.

2. Toilet Venting Issues Can Cause Methane Gas Exposure

Toilets are more than just a fixture — they’re connected to your home’s larger drainage and ventilation system. When that system is compromised, methane gas from your sewer line can escape into your living space. This often happens when a toilet’s vent stack is blocked or broken, or if the wax seal at the base fails completely.

Methane is flammable and can be harmful to breathe in enclosed spaces. If your bathroom smells like sewage or you notice bubbling in nearby drains after flushing, you may be dealing with a plumbing emergency tied to venting failure. This isn’t a job for DIY sealant or air freshener. Call our team immediately to inspect, isolate and correct the issue safely.

3. An Explosive Problem: Valve Failure On A Water Heater

Your water heater should have a temperature and pressure relief valve as a built-in safety mechanism. This prevents the system from overheating or exploding under pressure. If that valve fails, you’re dealing with a high-risk plumbing emergency. Water heaters under extreme pressure can rupture or burst, releasing scalding water and steam.

Warning signs include:

• Water or steam seeping from the valve
• Unusual rumbling sounds
• Visible deformation on the tank itself

If you notice any of these issues, turn off the water heater immediately and contact Oasis for emergency water heater repair in San Marcos. We’ll assess whether the valve, thermostat or entire unit needs replacement and restore safe operation.

4. Gas Leaks: Always A Plumbing Emergency

Gas leaks are dangerous, and they demand immediate attention. If you notice the following problems, evacuate your home and call for help:

• Smell of sulfur or rotten eggs
• Hissing sound near your lines or appliances
• Dying vegetation on your property
• Symptoms like dizziness or nausea indoors

Only call for help once you’re away from your property, as phone usage can present a fire hazard when a leak is present. Call your utility provider and emergency services to shut off your gas line and respond to the situation.

Once the gas is shut off and it’s safe to return, a licensed emergency plumber should be your next call. At Oasis, we provide expert gas line repair for homes in San Marcos, identifying the source of the leak and restoring safe, code-compliant operation.

5. Sewage Backups Require Immediate Cleanup And Repair

No one wants raw sewage in their home, but it happens — and when it does, it qualifies as a plumbing emergency. Whether it’s bubbling up in a shower drain or flooding your yard, sewage backups can expose you to harmful bacteria and quickly damage flooring, drywall and furniture.

Our team handles these messy situations with urgency. We’ll inspect your lines, clear blockages and make recommendations to prevent it from happening again. Depending on the cause, we may recommend ongoing drain maintenance or sewer line repair.
