A leaking water heater is the bane of any conscientious homeowner. Not only does it rack up water bills, but it could also wreak havoc on your home by causing water damage. If you have found yourself in this particular predicament, you are likely to want to figure out what’s going on ASAP! That’s why we’re here! So today, let our experienced team at Gahanna Plumbing & Drain guide you on your quest to discover why your water heater is leaking. 

Before we delve in: Please remember that your safety is paramount! Always power off the unit before starting any troubleshooting! 

Number 1: Loose Cold or Hot Water Inlet and Outlet Connections  

One of the most common causes of a water heater leak is due to loose hot or cold water inlet and outlet connections at the cold or hot water inlet and outlet pipes. These connections tend to loosen over time due to regular wear and tear. Consequently, water might leak out as a result of the loose connections, which can manifest as a tiny puddle around the heater’s base or even dripping from the pipes.  

To check this issue, check the connections around your water heater. If you spot water, your culprit might just be the loose connections. A simple twist of a wrench could resolve the issue but remember not to overtighten them as it could exacerbate the problem. 

Number 2: Defective Pressure Relief Valve  

Another potential culprit in the water heater leak saga is a malfunctioning pressure relief valve. This valve’s role is to vent out excess pressure within the tank. However, if it falls short in its duties, it can lead to water escaping. .  

To pinpoint if this valve is your problem, lift the valve’s lever slightly. If water comes out, then the valve is working. If it doesn’t stop leaking after you release it, this is a good signal that you may need to replace it. 

Number 3: Temperamental Temperature & Pressure Relief Valve  

Much like the other valve, the temperature and pressure (T&P) relief valve can be a potential leak source. Tasked with regulating the water heater’s temperature and pressure, a malfunctioning or loose T&P valve could lead to leaks. A leaky T&P valve may indicate water temperature is too high or the pressure within the tank is dangerously excessive. Keep in mind that both scenarios necessitate urgent attention. 

If you suspect the T&P valve is the problem, examine the vicinity of the valve for any moisture. Should it be damp, or you find water, a replacement might be in order.  

Number 4: Leaky Inlet Valve  

The inlet valve, which is the gatekeeper of cold water flow into your water heater, can also be a common cause of water heater leaks. If this valve is compromised or not adequately sealed, water might escape. A leaking inlet valve typically results in water pooling at the base of the heater. You might notice a relentless drip or a miniature waterfall from the valve zone.  

To troubleshoot, examine the inlet valve for signs of damage or wear and tear. A little tightening or possibly a replacement might be the way forward.  

Time to Call a Professional Plumber:  

If, after going through these simple troubleshooting exercises, your water heater continues to leak, it is time to call a professional plumber. Certain issues may be too intricate for do-it-yourself repairs. A seasoned plumber can expertly diagnose the predicament and propose a professional solution. This might encompass part replacements, rectifying internal tank problems, or even suggesting a brand-new water heater.  

Remember, postponing fixing a water heater leak will only result in damage to the unit itself or it can lead to water damage. When faced with a water heater leak that you cannot figure out on your own, it’s best to call a professional plumber.
