Some of the warning signs that would require immediate emergency repair for your water heater include water gathering around its base, a distinct burning smell that might be metallic or from gases, unusual noise, rust-colored hot water from your tap, and, most importantly, loss of all your hot water together with low water pressure. These factors put you at risk of facing a serious case of tank bursting, electrical hazards, or gas leakage that would need the attention of a professional plumbing contractor near you.
Most of the time, when your water heater fails, it does not give you much time to make up your mind. You should be able to understand the point of distinction between normal maintenance and a true emergency to avoid unnecessary costs that may amount to several thousand dollars due to water damage restoration.
Understanding the Point of Distinction between Normal Maintenance and Emergency Plumbing Problem
Not all plumbing problems require a hurriedly dispatched plumber. Small temperature changes and minor drips from pipes mean only that you are dealing with an aging component that will eventually fail and need regular maintenance.
Emergency plumbing is characterized by some danger to your property or your family’s life. With the tank seam or pressure valve being cracked, a regular water heater will let you down by dumping about 40 to 80 gallons of water in your house in a very short period of time. The national average cost of water damage restoration after an indoor plumbing burst ranges from $2,500 to $10,000, depending on whether carpet, subflooring, or drywall is affected.
Sign 1 – Pooling Water and Tank Base Leaks
If you find yourself in your utility closet or basement stepping into pools of water around the base of your water heater, take action immediately. While a leak could be as simple as a loose drain valve dripping, pooling water typically indicates corrosion or failure of the tank liner.
Two common failure points leading to high-pressure leaks are:
- Temperature and Pressure Relief (T&P) Valve Failure: The T&P valve serves as a pressure or temperature relief valve to avoid over-pressuring of your tank. In the case of failure or constant opening caused by internal overheating, the valve can release gallons of scalding water into your basement floor.
- Water Connection Lines Cracking: The flexible water connection lines connecting the cold and hot water flow are under constant pressure change. An old flexible braided line or copper line can crack, causing the release of water all over your walls and even electrical equipment.
In the case when the steel inner tank itself becomes compromised and cracked, the water will push through the tank outer casing. It cannot be fixed, only replaced, and it should be done after turning off the water main supply.
Sign 2 – Extreme Buildup of Sediments and Banging Noises
While the water heater is supposed to operate with some humming or clicking noise, any banging noises should raise an alarm. The banging sound comes from the water that is boiled inside and then trapped beneath the layer of sediments.
In the Greater Bay Area, where the water supply usually comes from municipal sources such as the East Bay Municipal Utility District (EBMUD), the water contains various mineral buildups depending on the district.
With time, the minerals become hard water sediment and accumulate at the bottom of the tank, covering the burner or lower electric element.
When the heating element activates, the water gets heated to extreme temperatures in an area where the sediments accumulate, causing boiling and popping noises. This localized overheating causes significant thermal stress to the glass lining of the tank, creating small micro-fractures in the inner steel shell.
Sign 3: Brown or Rusty Hot Water and Tank Interior Degradation
If you notice rusty or brown water coming out of your hot water faucets, but your cold tap water is crystal clear, the inner part of your water heater is wearing out.
Water heaters with tanks utilize the sacrificial anode rods as the core of the device that will attract all corrosive particles in order to prevent the steel tank from corrosion. Once the anode rod is worn out, corrosive particles start attacking the tank walls directly. The rusting metal flakes off and gets mixed into the hot water stream.
The appearance of the rusty water means that the walls of the inner tank are already getting too thin. Once the metal wears out enough, even the household water pressure will be strong enough to push the water through.
Sign 4: Gas Odor, Tripped Breaker, and Electrical Safety Threats
These warning signs of water heater problems create an immediate threat to the environment.
- Rotten Eggs Scent: If you smell the natural gas (the smell of rotten eggs), there is probably a leak in the burner assembly, thermocouple, or gas control valve. First of all, put out all flames, do not use any electrical devices, evacuate from the room, and then turn off the gas supply line and call for assistance.
- Electric Circuit Breaker Trips: If your electric or hybrid water heater keeps tripping its breaker, it most likely is experiencing a short circuit. It creates a very dangerous fire and shock hazard.
Sign 5: Loss of All Hot Water Along with Sudden Pressure Drops
It is annoying to wake up to a freezing shower; however, in cases when there is no hot water at all and the household water pressure decreases suddenly, this means something much worse than just a malfunction of the thermostat.
Loss of all hot water combined with pressure drops usually means:
- Blockage of the interior piping due to collapsed tank dip tubes or pieces of broken sediment.
- Severe hidden leakage from the main hot water pipe.
- Complete failure of the control board and thermostat of a modern electronic model.
In case you have noticed both signs, check the surrounding area of the water heater for hidden leaks prior to resetting or restarting the appliance.
Actions to Take While Waiting for Professional Help
To be ready for the arrival of the technician, do the following three actions. First, close the valve that supplies water to the water heater since this will help to stop the tank from refilling and leaking more water. Second, disconnect the power source of the water heater: turn off the gas in the shutoff valve for a gas model or trip the breaker for an electric and heat pump model if you can access it. Finally, take away all valuable and electronic items from the room and clear the way to the appliance.
