Your water heater works hard every day, and a little maintenance goes a long way toward keeping it running efficiently. Here are the most important steps Queens homeowners can take to extend the life of a tank water heater.
First, flush the tank annually. Over time, minerals from NYC's water supply settle at the bottom of the tank, forming a layer of sediment. This sediment insulates the water from the heat source, making the heater work harder and costing you money. A professional flush removes this buildup and restores efficiency.
Second, check the temperature setting. The recommended setting is 120°F — hot enough for comfortable showers and cleaning, but not so hot that it wastes energy or risks scalding. If your heater is set higher, lowering it saves energy and slows sediment buildup.
Third, test the pressure relief valve. This safety device releases excess pressure to prevent the tank from over-pressurizing. To test it, carefully lift the valve's lever — water should flow out and stop when you release it. If nothing happens, or if the valve leaks continuously, it needs replacement.
Watch for warning signs that your water heater needs professional attention: rumbling or popping sounds (sediment buildup), rusty or discolored hot water, water pooling around the base, or a pilot light that won't stay lit. Any of these could mean a repair is needed — or that replacement is the better value.
A typical tank water heater lasts 10–12 years. If yours is in that range and having problems, it's worth getting a professional opinion on whether to repair or replace before it fails completely. A planned replacement is always less stressful than an emergency one.
