To reduce water heating costs: Opt for showers over baths and limit shower time. Lower your water heater's temperature. Turn off water when not in use, especially while doing dishes. Insulate your water heater and pipes to prevent heat loss. Consider upgrading to an energy-efficient water heater, like tankless or hybrid units. Look for energy-saving dishwashers and washing machines to further cut costs.

Normally, a pipe attached to the water heater drain pipe is a recirculation line. While not absolutely necessary, a recirculation line keeps water in the pipe hot and reduces the amount of water wasted before you get hot water. The pipe could also be for a pressure relief line. If it goes to a floor drain, then it is a pressure relief line.

To maintain your water heater: Inspect for rust or blackened areas, especially on gas units, and call for help if found. Check all piping for corrosion to prevent malfunctions. Use a gas leak detector to check for leaks and ensure the gas valve, draft hood, burner, pilot light, and flame color are in good condition. Test the thermostat and ensure proper functioning of hot and cold water pipes. Test the temperature/pressure relief valve annually for leaks. Check the anode rod every two years and replace if needed. Drain a gallon of water monthly to remove sediment buildup for a thorough inspection.

For gas water heaters, it's crucial to follow the National Fuel Gas Code, which mandates an 18-inch elevation off the ground for safety. This rule helps prevent fires and explosions, particularly in areas where flammable substances might be present. While not required for basement installations, adhering to this standard is wise. Remember, the 18-inch distance is measured from the ground to the pilot light, not the bottom of the heater. Ensure the stand supporting the heater is sturdy enough for a full tank. Regulations may vary by city, so check local codes before installation.

To save on water heating costs and overall energy bills: Lower your water heater's temperature to 120°F to reduce energy consumption and prevent scalding. Take shorter showers and avoid baths to minimize water usage. Turn off the water while brushing teeth or shaving. Wash full loads of dishes with shorter cycles and opt for cold water for laundry. Consider upgrading to a modern, energy-efficient water heater or a tankless model. Seal windows, doors, and other openings to prevent warm air from leaking out. Add extra insulation in the attic and use thick curtains or transparent film on windows. Set your thermostat to a consistent temperature or program a smart thermostat for efficiency, adjusting it before returning home.

Do not replace the water heater without first checking out the pressure balance faucet in the shower. Pressure balance and temperature control shower faucets are notorious for reducing the hot water pressure as you are using the faucet. Temperature control shower faucets use a spring that adjusts the hot water temperature down when it senses a change in the water temperature. Unfortunately when the spring gets old, it doesn't function as it was intended and you lose hot water temperature.

If you're experiencing a sudden loss of hot water, the culprit may be a faulty dip tube. This tube directs cold water to the bottom of the water heater for heating. If it becomes detached, cold water mixes with the hot water at the top, resulting in reduced hot water supply. To fix this issue, inspect the dip tube by pulling the cold water inlet pipe and ensuring its condition.

Cold temperatures can cause water heater metal to expand and contract, potentially leading to leaks, especially in older units or those in unheated areas. Sediment buildup can exacerbate this issue. Regular maintenance and inspection, including checking for bends or cracks in the tank, are crucial. Watch for signs like slow heating or depleted hot water supply. DIY fixes such as adjusting the thermostat or adding insulation may help, but if unsure, it's best to consult a professional plumber like City Plumbing pro for thorough inspection and repairs.
