Greensboro Water Heater Repair

When is the worst time to need water heater repair? Holidays, weekends, between 5 pm and 9 am, parties and family gatherings, while you're doing the laundry, taking a shower, or washing dishes. When is the best time to need water heater repair? Never!

Johns Plumbing provides expert water heater repair in Greensboro, Winston-Salem, and High Point, but there are ways to extend the life of your water heater. Here are a few tips that Johns recommends to help keep your water heater in tip-top shape.


1. Drain the water from the tank once every three months. This helps to remove the buildup of sediment in the bottom of the tank. When sediment builds up, it interferes with the transfer of heat so the bottom of the tank overheats. This weakens the tank and the glass lining. If you're water heater is electric, sediment buildup can come in contact with or bury the lower element so that it burns out. What else can sediment buildup do?

  • Slip into the recirculation lines ultimately resulting in burning out the recirculation pump.
  • Clog the drain valve so that you can't access the only clean water source in case of an emergency.
  • Cause some frightful noises that are very disconcerting for both children and adults, particularly late at night.

2. If it's a gas water heater, check the pilot light: This should be blue with a yellow tip. If not, call a professional for an adjustment. Also check for soot buildup which can clog the flue and results in carbon monoxide gas building up in your home.

3. If it's an electric water heater, check the sacrificial anode rod for a buildup of hardened calcium carbonate. (You may recognize calcium carbonate as that white, chalky-sandy, concrete-like yutz from the kids' vaporizer or the coffee maker). The sacrificial anode rod is put into the water heater for no other reason than to draw corrosion out of the water thereby protecting the inside of the water heater. If the calcium carbonate is soft, you can wipe it off with a old cloth. If it is hard, (doesn't wipe off or flakes off) the anode rod probably isn't meeting its potential and should be replaced.

4. Get a contractor to inspect your water heater once every two years. Potential problems may be spotted and fixed quickly (cheaper), saving you from having to replace the water heater in the very near future (more expensive than a water heater repair).
