Water heaters are an absolute necessity. This is one of the most important components of your plumbing system. The last thing you want is to wake up unceremoniously to cold water running from your shower. It is therefore a must that you ensure that this device is in good running condition. If you are having water heater problems there is a big chance that you can have it repaired rather than replacing it outright. Replacing the water heating element and the pressure-relief valve are the most common issues that crop up in water heaters.

Should You Repair or to Replace Your Minnesota Hot Water Heater?

A good rule of thumb to follow when thinking of repairing or replacing you water heater is to base your decision according to the manufacturer’s suggested service life. On average, water heaters last for about eight to twelve years depending on design, location, and correctness of installation, maintenance and quality of water.
If you have a water heater in your home that is more than ten years old and is already leaking or failing to heat water regularly or even not at all, it is safe to say that it is time to have it replaced. It is important however, to also determine that you do not have an electrical issue such as a tripped breaker or a broken fuse that may have caused it to fail.

Repairing Water Heaters in Minneapolis and St Paul MN

Electric Water Heaters – The first step is to ensure that the power supply is connected and then reset the thermostat. Flush the device in order to get rid of any sediment present in the tank. Make sure that you insulate the hot water pipes. Replace the heating element or thermostat according to manufacturer recommendations and then raise the temperature setting to your desired level.

Gas Water Heaters – Ensure that the gas is connected and the pilot light is on. Remove any sediment present from the tank by flushing it and then insulate the hot water pipes. Next step is to clean the gas burner and then replace the thermocoupler. This is a safety device that shuts off the gas automatically when the pilot flame is extinguished. Place the temperature setting back to the desired level.

Hissing Noises – are usually caused by built-up sediment in the tank. All that needs to be done is to drain the tank until such time that the water clear and then submerge the element in a pan with white vinegar for at least one hour and then remove the gunk by scraping.

Leaking Pressure-Relief Valve – Replacement of the valve is the only option.

Leaking water supply pipes – Make sure the fittings are tight. If the problem persists, shut the water supply off first and then replace the fittings as needed.

Water Heater Replacement

If it is absolutely necessary that you replace your water heater, consider getting an upgrade that offers more features and less maintenance. Here are some features that you should consider. (We can help you choose the right water heater for your home’s specific needs)

Gallon Capacity – Select either a forty or fifty gallon heater, as these are the most common ones used in homes.

Recovery Rate – Make sure that you are aware of the number of gallons that the heater can heat in one hour.

Dimensions – This include the height and the width as you need to know whether or not it will fit in the space that you want to install it.

Energy Efficiency – To save on electricity costs, determine the heater’s energy efficiency rating which a sticker located on the side of the device that shows the estimated cost of operation represents.

Installation of Water Heater

We install all types of water heaters, but if you wanted to do it yourself…this is what you’d typically do.

  1. Turn off electricity at the breaker.
  2. With the water supply on, turn the faucet on hot and allow to run cool and then shut down the cold water supply line. Attach a garden hose to the drain valve located at the bottom of the heater.
  3. Open the drain valve and empty water.
  4. Once, the tank is empty, take out the discharge pipe from the T&P or temperature and pressure relief valve and then disconnect the water supply lines.
  5. Put the new unit in a drain pan.
  6. In case your unit did not come with a new T&P relieve valve already installed, do not worry as all you need to do is to twist in the new valve. Never re-use the old one. Take note that the T&P valve automatically opens if it detects high temperature and pressure that is too much for the tank to handle.
  7. Begin installing the discharge pipe from the T&P relief valve toward the drain or bucket to catch dripping water.  Cut the pipe to no more than six inches above the bucket.
  8. Use a flexible hose kit for water hook-up and then apply plumber’s tape to the threads of the heat trap nipples and then reconnect the hoses.
  9. Use plumber’s tape on one end of a connector body threads. Secure the fitting to the hose and then hold it to the pipe. Make sure that there is a bit of slack. Mark and cut the pipe.
  10. Slide the compression nut and ring onto the pipe and then push the pipe into the fitting and then tighten the nut.
  11. Fill the tank and then remove the aerator from the nearest faucet and then open the hot side. Turn the water supply on slowly and look for any leaks along the connections. Once you confirm there aren’t any leaks, you can then fill the tank.
  12. Attach the wirings.  Begin with the ground wire to the green ground screw.  Once the wires are connected, turn the power on at the circuit.
  13. Check manufacturer recommendations on the temperature settings. It may take some time before the water heats up.
  14. Wait for a few hours and then check the discharge pipe.  If there is dripping then the pressure is a bit high. Simply lower the pressure to at least 80 PSI.
  15. Enjoy your hot water.
