Ignoring a water heater leak, no matter how small it seems, is not an option. That slow drip can escalate rapidly into a major flood.

Is Your Water Heater Leaking? What to Do NOW
If you've found water around the base of your hot water heater, it's important to take immediate action to prevent further damage and ensure safety.
- Shut Off the Water Supply: Find the cold water inlet pipe at the top of the water heater. There should be a valve on this pipe (usually a handle or knob). Turn it clockwise until it's tight to shut off the flow of water into the tank. This stops the source of the leak.
- Shut Off the Power:
- For Electric Water Heaters: Go to your home's electrical panel (breaker box) and locate the circuit breaker labeled for the water heater. Flip the breaker to the "off" position. If it's not labeled, you may need to flip the main breaker, but be aware this will shut off power to your entire home.
- For Gas Water Heaters: Locate the gas shut-off valve on the gas line leading to the water heater's control valve. This valve is typically a lever or knob. Turn it perpendicular to the pipe to shut off the gas supply. Also, turn the thermostat dial on the water heater's control valve to the "off" or "pilot" setting.
- Assess the Situation: Try to determine where the water is coming from. Is it dripping from a valve, a pipe connection, or seems to be coming from the tank itself? Place towels or buckets to contain the water.
- Do Not Attempt Complex DIY Repairs: Water heaters involve high pressure, high temperatures, and potentially gas or high voltage electricity. Unless the leak is a simple, obvious issue like a loose pipe fitting you are comfortable tightening, it's best to call a professional plumber immediately.
Taking these initial steps can significantly limit the amount of water damage and ensure your safety while you wait for assistance.

Why is Your Water Heater Leaking? Common Causes Explained
Water heaters are complex appliances, and leaks can originate from various points. Understanding the potential source can provide clues about the severity of the issue. Our plumbers in Castle Hills, TX are experienced in diagnosing leaks from all common sources, including:
- Drain Valve Leaks: The drain valve (usually located near the bottom of the tank, used for flushing sediment) can wear out or become loose over time, leading to drips or leaks. These are often repairable by tightening or replacing the valve.
- Temperature and Pressure (T&P) Relief Valve Leaks: The T&P valve is a crucial safety device designed to release water if the temperature or pressure inside the tank gets too high. If this valve is leaking, it could mean the valve itself is faulty and needs replacement, or more seriously, that there's excessive pressure or temperature in the tank, which requires immediate professional investigation.
- Inlet and Outlet Connection Leaks: The connections where the cold water enters the tank (inlet) and hot water leaves (outlet) can develop leaks over time due to corrosion, loose fittings, or expansion and contraction. These leaks are often repairable by tightening connections or replacing fittings.
- Heating Element Gasket Leaks (Electric Water Heaters): Electric water heaters have heating elements submerged in the tank. The gaskets sealing these elements can fail, causing leaks where the element connects to the tank.
- Tank Leaks (Corrosion): This is often the most serious type of leak. The metal tank inside the water heater is lined to prevent corrosion, but over many years, this lining can degrade, leading to rust and eventually small cracks or pinhole leaks in the tank itself. Leaks originating from the tank body typically indicate the tank has failed and the unit needs to be replaced.
- Leaks from Nearby Plumbing: Sometimes, water found near the water heater isn't from the heater itself but from connecting pipes or nearby plumbing fixtures. A plumber can help determine if the water source is truly the water heater or a related Pipe Leak Repairs.
Diagnosing the exact source of the leak requires expertise to ensure the correct repair is made or to confirm if replacement is necessary.
A Leaking Water Heater is Often an Emergency
Don't underestimate the urgency of a water heater leak. Even a small, slow leak can lead to significant problems:
- Water Damage: Water can seep into floors, walls, baseboards, and subflooring, causing warping, rot, and costly structural damage.
- Mold Growth: Excess moisture creates a perfect environment for mold and mildew, which can start growing within 24-48 hours and pose health risks.
- Safety Hazards: Leaks near electrical components can create shock hazards. Gas leaks from a damaged gas water heater are extremely dangerous. Standing water around a gas appliance is also hazardous.
- Reduced Efficiency: A leaking tank means the unit is constantly trying to heat and hold water that's escaping, wasting energy and increasing utility bills.
Because of these potential issues, most water heater leaks in Castle Hills, TX should be treated as an urgent matter requiring prompt professional assessment.
Our Expert Water Heater Leak Repair Services in Castle Hills
When you contact us about a leaking water heater in your Castle Hills home, our experienced plumbers prioritize your situation. We arrive equipped to diagnose the problem accurately and provide a clear path forward.
Our process includes:
- Safety Assessment: Our technician will first ensure the area is safe, confirming that the water and power/gas supplies have been correctly shut off or safely doing so if they haven't been.
- Leak Source Diagnosis: Using their expertise and potentially Leak Detection + Repair tools, they will pinpoint the exact origin of the leak.
- Assessment of Damage: They will assess the water heater itself and the surrounding area for any visible damage caused by the leak.
- Repair or Replacement Recommendation: Based on the type of leak, the age and condition of your water heater (whether it's a standard Water Heater or a Tankless Water Heater), and the potential cost of repair, our plumber will provide a professional recommendation.
We aim to provide effective Water Heater Repair whenever possible. However, if the tank itself is leaking or the unit is old and repairs are extensive, replacement may be the more cost-effective and reliable long-term solution.
Repair or Replace? Making the Right Decision
Deciding whether to repair your leaking water heater or replace it depends on several factors:
- Age of the Unit: Standard tank water heaters typically last 10-15 years. If your unit is approaching or beyond this age and is leaking from the tank, replacement is almost always the better option. A newer unit with a minor valve leak might be a candidate for repair.
- Source of the Leak: Leaks from valves or connections are often repairable. A leak directly from the tank usually means the unit needs to be replaced.
- Cost of Repair vs. Replacement: Consider the cost of the repair in relation to the cost of a new water heater and installation. If the repair cost is a significant percentage of replacement, investing in a new, more efficient unit may be wise.
- Energy Efficiency: Newer water heaters, including Tankless Water Heaters or high-efficiency tank models, can offer significant energy savings compared to older units.
- Warranty: Check if your current water heater is still under warranty.
Our plumbers will discuss these factors with you honestly and provide recommendations based on your specific situation in Castle Hills. Roadrunner Plumbing & Air provides various options for different types and sizes of water heaters if replacement is needed.

Frequently Asked Questions About Leaking Water Heaters
Where do water heaters commonly leak from?
Leaks often originate from the drain valve, the temperature and pressure (T&P) relief valve, inlet/outlet connections, heating element gaskets (on electric units), or the tank itself due to corrosion.
How much does it cost to fix a leaking water heater?
The cost varies significantly based on the cause and location of the leak. A minor valve replacement is much less expensive than replacing a unit with a leaking tank. Repair costs also depend on labor time and parts needed. Our plumbers provide an assessment and options before work begins.
Who should I call for a leaking water heater in Castle Hills, TX?
You should call a licensed and experienced local plumber specializing in water heater repair and installation. They have the expertise to diagnose the issue safely and effectively.
Is a water heater leaking from the bottom an emergency?
Yes, a leak from the bottom is often a sign that the tank itself has failed due to corrosion. This type of leak usually means the unit needs immediate replacement to prevent significant water damage and ensure safety.
Can I repair a leaking water heater myself?
While some very minor issues like a loose connection might seem simple, working on water heaters involves risks like scalding temperatures, high pressure, and electrical or gas hazards. Attempting complex repairs yourself can be dangerous and may cause more damage. It's strongly recommended to call a professional plumber for leaking water heaters.
