Gas Water Heater Repair in Dublin

Water heater diagram.Gas water heaters can have very particular problems. Some of the most common gas water heater repair issues include:

  • Not producing hot water – When your water heater stops producing hot water, it’s most likely caused by a problem with the pilot light, the pilot control valve, or the gas thermocouple. The thermocouple works with the gas pilot to help ignite the natural gas to heat your water.
  • Producing water that isn’t hot enough or doesn’t stay hot long enough – Water that goes from hot to cool or is just lukewarm may indicate gas supply or control problems. It could also be that the dip tube (which sends cold water to the bottom of the tank) is broken. Or it may be that the hot and cold water connections crossed during installation.
  • “Rusty” water – Corrosion has most likely formed inside the tank’s glass liner. Or the anode rod—an aluminum or magnesium rod that slowly dissolves into the tank to prevent corrosion—may be failing.
  • Smelly water – A “rotten egg” smell is most often caused by bacteria forming in the tank’s built-up sediment.
  • Rumbling or banging – The bottom of the tank may be overheating due to sediment buildup, causing the water to boil, which can make loud noises.
  • Leaking – If you notice water leaking around the bottom of your water heater, it can mean that the temperature-and-relief valve may be damaged, or there is a leak from the tank or a plumbing connection.

Whatever the problem is, call Moore Mechanical for East Bay gas water heater repair, and we’ll come check it out! Dial 925-307-6479 or contact us online.

Electric Water Heater Repair in Dublin

Electric water heaters break down much the same as gas water heaters, but the causes can be different. Below is a list of some typical electric water heater problems.

  • Electric water heater isn’t producing hot water – A broken thermostat or malfunctioning upper heating element are most likely the cause of a hot water loss.
  • The water never gets hot enough or doesn’t stay hot long enough – The electric water heater’s upper and lower elements may be worn out.
  • The water is too hot – Your heater’s thermostat is probably turned up too high. Make sure it is set between 110 and 140 degrees Fahrenheit. If the water is still too hot, the thermostat is likely broken.
  • “Rusty” or discolored water – Just like in a gas water heater, corrosion has probably formed inside the tank or the anode rod is failing.
  • High-pitched, “whining” noise coming from the water heater – A layer of scale has likely built up on the electric heating elements.
  • Rumbling or banging noises – Just like in a gas water heater, built-up sediment is overheating the bottom of the tank, causing the water to boil.
  • The water is giving off a foul odor – That “rotten egg” smell is usually caused by bacteria forming in the tank’s built-up sediment.

Tankless Water Heater Repair in Dublin

Tankless, or “on-demand,” water heaters are efficient and compact, making them highly valued by homeowners looking to save water and energy. But like any household appliance, they can have issues, including:

Mineral buildup – Hard water can cause calcium mineral buildup. A water softener or scale filter will usually keep the buildup from happening.

Combustion shutdown – Venting is a critical element when installing a tankless water heater. Incorrect installation, or venting tubes that are too long, may result in poor ventilation and shutdown.
