Defects observed at the water heater by the home inspector
Now let's take a look at your water heating equipment. We need to make sure it's working because it's never fun taking a cold shower.The most common types of water heating equipment found in residential homes are an electric, or gas water heater it may be a tank type or could be a newer tank less type of water heater. No matter what type you have there still can be defects and hazards present. If the temperature sensor fails the unit will continue to heat the water. This can be very dangerous as the unit heats pressure can build and if the temperature relief valve fails your water heater can project through the ceiling of your home or roof depending on the location. As you can see this would create a very dangerous hazard for you and your family and even others near your home. It is highly recommended that a plumber test your temperature relief valve once a year. Due to temperature relief valves leaking after testing I do not test these. Water heaters are tested inspecting unit for any corrosion or evidence of back drafting meaning the exhaust gases that are supposed to be going to the exterior are coming back into the home. This is a very hazardous condition that needs corrected immediately carbon monoxide may enter into your living space. There can be a lot of areas that can have corrosion present. The water heater itself can have corrosion in many areas. Changing the anode rod can help to stop corrosion at other areas of the water heater. This rod sacrifices itself meaning it rust before the exposed steel at the inside of your water heater. you can increase the life of your water heater if the anode rod is changed about every five years. Once your tank starts to rust than leaks are not far behind. Many times there may be corrosion at plumbing supply connections. Corrosion at nipples, Leaks at water heater tank, or plumbing supplies at water heater, The temperature relief valve is leaking. The temperature relief valve may be missing drain line, it may not drain to the exterior of the home, also the drain line may not be installed with the right materials, the drain pan may not be present, drain pan could be rusted or clogged, If located in the garage area it may not be protected against physical damaged or may not be 18' above the floor which can create a fire hazard situation , damaged or missing components etc. these are some of the defects and hazard that may exist at the water heater. During your home inspection service I will thoroughly inspect the water heater noting the defects and make it clear what hazards may exist so you and your family are safe. If to many defects are present I will recommend that the water heating unit be replaced. Plan on getting about 10 years of life out of your water heater. Once you move in make sure to have an annual inspection of the unit this can alert you to problems and may save money if leaks are present that could do damage to other areas causing damage to drywall insulation. If left unchecked a leaky water heater can cause conditions conducive to mold growth and that can be a hazard to your health.
