Saint Louis Water Heater Repair And Replacement


There is nothing more frustrating than turning on the hot water only to have cold water come out!  Luckily Armstrong Plumbing are your Saint Louis area water heater repair specialists! Our decades of experience have taught us how to tackle many water heater issues on all of the top brands. We have seen it all, and we  know the best way to repair it the first time. We can even be there same day to help you. 

Of course, before you call a plumber there are some ways to troubleshoot a problem with your hot water heater. The methods vary based on the type of water heater that you may have. 

  • Electric Water Heaters: Ensure the breaker that services the water heater has not tripped. If that doesn’t solve the problem, open the panel on the outside of the tank and hit the “reset” button.
  • Gas Water Heaters: These are a bit more challenging, but you can check the pilot light to see if it is still lit. If it is not, turn the gas off as soon as you can.

Water Heater Replacement

Perhaps you would like to be more energy efficient in your home. Tankless water heaters offer smart solutions for users who want to save a little green while going green. A tankless water heater can save the average homeowner money over time, simply because the units are far more energy efficient. Since the units offer hot water on demand, only taking the energy to heat the water needed, it is far less of a drain on the homes utilities. 

This on demand heating means that a tankless water heater can provide unlimited hot water when you need it. No more cold showers when the dishwasher is running! You can heat water for multiple appliances at a time. Since no tank is required, they also take up much less space than traditional water heaters.

Signs of Water Heater Failure

There are many reasons that a water heater will fail. In fact there may be tell tale signs that your water heater is in trouble way before the hot water runs out. If you experience any of these signs, you may want to reach out to Armstrong Plumbing for a service call. We can check on your water heater to determine if trouble is headed your way, before the system fails completely. Here are some of the telltale signs that your water heater may be about to fail: 

  • You only have cold water

  • Your water gets warm, but never hot

  • Your water heater makes a rumbling noise

  • Your hot water is rusty, muddy or discolored

  • Your water has a metallic smell or taste

  • Water is leaking around your water heater

These issues can come from a number of causes from internal rust to sediment build up. Did you know that high water pressure, while a great feeling for showers, can be detrimental to your water heater? The wrong size heater for your home may lead to problems as well. A too-small unit may have to work too hard in your house leading to early failure of the heater. Our plumbers will look at every aspect of your plumbing system to make sure you have the right solution for your home. Of course, one of the biggest issues with water heaters is age. Unfortunately, over time, these machines break down and need to be replaced. 

Working in the plumbing industry for decades, we have seen almost every type of water heater problem, but the solution is always the same. Simply reach out to Armstrong Plumbing for a quick and easy service call.
