What Do I Do if My Water Heater Is Leaking?
If you find water around your water heater, there are many ways to stop it from continuing to leak and find out where it’s coming from. Before contacting a professional, you can do a few things to look for the cause of leaking water:
- Shut off the power or gas to the unit
- Turn off the cold water supply valve above the tank
- Place towels or a shallow pan to contain any standing water
These initial steps can help to keep you safe and protect your house while you investigate further
If the water is still visible, you will want to look deeper to get a better understanding of where it’s coming from. The following are some common areas, discovered over the years, where we have found water heater leaks in Southern CT:
Check the Cold Water Inlet and Hot Water Outlet Connections
Older water heaters develop leaks at the connection points on top of the tank.
- Visually inspect both pipes where they meet the tank for moisture or corrosion
- Gently feel the fittings which should be dry, not damp or rusty
- If a fitting is loose, it may simply need to be tightened (carefully and only if you’re comfortable doing so)
If you have a small drip at the connection point, it’s usually easier to fix than if there is a leak from the tank. If the drip is still present after you have tightened it, call a professional for assistance.
Inspect the Temperature & Pressure Relief Valve (T&P Valve)
The Temperature & Pressure (T&P) valve is designed to open and release water to protect the water heater from overpressure or temperature; it’s good when this happens but it can also be an indication of something wrong with the water heater.
- Trace the discharge pipe down from the side or top of the tank
- Check whether water is dripping from the end of the pipe or from the valve itself
- A constantly leaking T&P valve may mean excessive pressure, an overheating tank, or a failing valve
If you find that the T&P valve is leaking, get assistance from a licensed professional.
Check the Drain Valve at the Bottom of the Tank
Near the bottom of the water heater there is a drain valve that is utilized both for flushing and maintenance. Over time, this valve is subject to developing leakage issues.
- Look for water dripping from the valve handle or spout
- Make sure the valve is fully closed
- If it continues to drip when closed, the valve itself may be worn out and need replacement
The repair of leaky valves is typically simple. However, the longer the valve sits leaking, the more water that will flood the area beneath the water heater.
Inspect the Bottom of the Tank
If you discover water underneath the water heater and have checked each of the inlet and outlet connections to the water heater and there is no evidence of leakage from either connection or valve, you may have a leaky tank.
- Look for rust, corrosion, or staining along the bottom seam of the tank
- Check the drip pan (if there is one) for standing water with no visible source from above
- Sediment buildup over the years can cause internal corrosion that eventually breaks through the tank
Unfortunately, your only option will be to replace the tank; a leaky tank is almost always beyond repair. If your tank is leaking, it may be time for you to consider upgrading your water heating system to a more efficient alternative such as a tankless or hybrid water heater.
Don’t Overlook the Pipes Around the Unit
In addition to a leaking tank, sometimes we mistake plumbing problems that exist around our water heater for leaking water from the water heater.
- Check supply lines, shut-off valves, and any nearby joints
- A leak from the ceiling or an another pipe can drip down onto the unit
- Condensation on cold water lines can also mimic a leak during humid Connecticut summers
By doing a thorough inspection and tracing all of the plumbing connections associated with the water heater, you might see that there are no leaks from the water heater.
Your Water Heater Is Still Leaking, Now What?
If you have checked all of the probable sources and still have not identified a source of water below the water heater, you should take immediate action to limit further damage caused by pooling water. You should also prepare to be without hot water until a professional can come to provide water heater repair services.
Contain the Water
A small leak can quickly turn into a big mess. While you wait:
- Place towels, a bucket, or a shallow pan under the leak
- Move boxes, tools, and anything else stored nearby up off the floor
- Use a wet/dry shop vac if water is starting to spread
Catching and containing water early helps prevent damage to flooring, drywall, and anything stored in the room.
Shut Off the Water and Power
If you haven’t already, make sure the unit is fully isolated:
- Close the cold water supply valve above the tank
- For an electric unit, switch off the breaker that powers the water heater
- For a gas unit, turn the gas control valve to the “off” or “pilot” position
This protects your home from continued water flow and removes the heat source while the unit is compromised.
Plan Around No Hot Water
A short stretch without hot water isn’t fun, but it’s manageable:
- Heat water on the stove if needed
- Hold off on laundry until the unit is repaired or replaced
- Consider visiting a family member or gym for a hot shower if the wait is longer
Knowing what to expect helps reduce the stress of being without your usual hot water supply.
When Should I Call a Water Heater Professional?
If you have tried to locate your water leak but were unable to find it or if you still can’t stop it from leaking, you may now have a tank leak. If you believe your leak is from the tank itself, it’s best to contact a professional. One or more of these is likely your issue:
- A failed T&P valve or pressure issue
- A worn-out drain valve or internal component
- A corroded or split tank that needs full replacement
- A new, more efficient system better suited to your home
If you choose to contact a professional, you’ll have options: repair vs. replace, tank vs. tankless/hybrid.
