What Type of Water Heater Do You Have?
Before diving into the most common water heater problems, it’s essential to understand the different types of water heaters available on the market. Knowing which type you have can help diagnose and resolve issues more effectively. The two main types of water heaters are traditional and tankless.
Traditional tank heaters are cylindrical tanks that store and heat a large amount of water at a time. These are the most common type of water heater found in many households, and they require regular maintenance to ensure optimal performance. On the other hand, tankless heaters use high-powered burners to heat water as it passes through a heat exchanger, providing endless hot water on demand. They have become increasingly popular due to their energy efficiency and compact size.
COMMON CAUSES OF WATER HEATER LEAKS
Should you find your water heater tank leaking, it might be attributed to a variety of potential culprits. The most probable reasons are rust and corrosion. However, there are other factors that could instigate water heater leaks, such as
- Defective temperature and pressure relief valves
- Inappropriate levels of water or gas pressure
- Valves that have become unmovable
- Units that are running too hot
- Unsecured bolts attached to the burner element
- Compromised gaskets
- Problems associated with the dip tube
- Leakage emanating from adjacent plumbing joints
As a property owner, you have the capacity to inspect any discernible loosened plumbing connections, ensuring they are tightened just enough to possibly halt the leak. Also, a detailed visual examination of the tank is advisable to spot clear indications of wear and tear. If the tank itself is leaking, the only viable solution is to get in touch with your plumber to arrange a new water heater installation.
COMMON PROBLEMS WITH WATER HEATER TEMPERATURE
No hot water
Are you encountering a full water tank without any hot water? The problem likely lies with your heat source. Electric water heaters might suffer from failed heating elements or impacted electrical connections. On the other hand, a gas water heater issue could stem from a bad pilot light or a faulty gas connection. If the gas doesn’t ignite despite the lit pilot light, the problem may be regarding the burner itself, necessitating repair. For those with newer heaters boasting electronic ignition systems, a trip to your breaker box might reveal a tripped circuit breaker or blown fuse associated with your water heater. Resetting it should reignite and restore your hot water supply.
The water is warm but not enough
There are several potential explanations for your hot water supply predicament, which could include a water heater tank that is too small, mistakenly interchanged hot and cold connections, or persistent issues with either the burner element or the thermostat. Engaging a plumber’s services can yield viable solutions, whether that be executing necessary repairs or recommending an upgrade to a more substantial water heater.
Low Hot Water Pressure
Another issue you may encounter is low hot water pressure. This can indicate sediment buildup in the tank, blocking the water flow. Homes of a certain age often face the challenge of limited water pressure due to the smaller ½” plumbing, which used to be the construction norm for many years. Today, newer residences feature larger ¾” plumbing that accommodates increased water flow. The only resolution to this problem in older homes would necessitate an entire repiping, which is undoubtedly daunting.
However, if your residence is equipped with contemporary plumbing, you might have the opportunity to enhance your water pressure. This can be achieved by ensuring that the aerators in your sink are free from clogging, a common issue of water heaters that develops over time. Additionally, examine the water inlet valve to ascertain it hasn’t inadvertently been partially closed.
Water is too hot or cold
Experiencing water temperatures that are either too high or too low can be symptomatic of a faulty thermostat or heating element, or it could simply be a result of inappropriate settings. Standard factory settings for water heaters are usually around 120 degrees Fahrenheit, which may either be excessively high or insufficiently warm for certain users. If your water supply is consistently leaning towards the colder side, adjust the thermostat to 140 degrees and give it an hour before reevaluating the temperature. Despite making adjustments, persistent cold water can point towards a potential issue with the thermostat or heating element.
How do we solve this problem?
Electric water heaters have two heating elements intended to heat the top and bottom of your water tank. It’s recommended that you check both elements for any indications of damage or malfunctioning, such as burn marks or corrosion. If you find any issues with either element, they will need replacing.
On the other hand, gas-powered water heaters usually only have one burner element, so the issue is likely related to your thermostat. To test if it’s functioning correctly, turn up the thermostat setting and wait for the water to heat up before adjusting it. If this isn’t effective in regulating the temperature of your water, it may be time to replace your thermostat.
If the temperature remains constant, contact a professional to diagnose and resolve your problem.
Other Most Common Water Heater Problems In Your Home
Dirty Or Rusty Colored Water
One of the common water heater issues you may face is the rusty color of the water.
