Whether you are showering, washing dishes, or doing laundry, your water heater has to keep up. You probably take it for granted until you turn on the tap on there’s no hot water.
In the Scottsdale area, hot water heater problems happen more often than you might expect. We’ve got hard water here and that can cause mineral buildup in your system, putting extra strain on your system. Our extreme high temperatures and older plumbing systems don’t help either.
When your hot water heater is not working right, it’s a major inconvenience. But the longer you wait to deal with it, the more expensive it can get. So, this guide will help you understand some of the common problems that affect hot water heaters in Scottsdale, AZ, the simple repairs you may be able to do yourself, and when it’s time to call in the experts.
Hot Water Heaters in Scottsdale
The type of water heater you have will determine what you may need to do when you’re having problems, so let’s walk through the most common options in Scottsdale.
Gas Water Heaters
Gas heaters are common throughout Arizona, heating water quickly and efficiently. However, they are sensitive to ignition issues, sediment buildup, and gas pressure problems. There are also safety systems built in to help prevent overheating and dangerous situations, so a shutdown may be a sign of a serious problem.
Electric Water Heaters
Electric units are simple and reliable, but tend to have slower recovery times. Heating elements, thermostats, and sediment accumulation are common sources of failure.
Tank Water Heaters
Standard tank heaters are cost-effective, but require regular maintenance because Scottsdale’s hard water creates significant mineral buildup inside the tank.
Tankless Water Heaters
A tankless water heater in Scottsdale heats water on demand. They are highly efficient, but require annual descaling because Arizona’s water quality accelerates mineral buildup inside the heat exchanger. Without regular flushing, they can lose efficiency or shut down unexpectedly.
Hybrid and High-Efficiency Heaters
Some Scottsdale homeowners choose hybrid or high-efficiency systems for long-term savings. These systems require specialized installation and service.
Because each system has unique needs, you want a technician who knows how to diagnose the exact cause of the issue and keep your heater running safely. This is where experienced teams like those at George Brazil make a difference.
Choosing the Best Water Heater Installation for Your Home
Which system is right for your home? You have options, and our technicians can explain them to make sure you choose the best water heater installation for your home. A big part of your decision will be making sure the system matches your home’s size and water needs.
You’ll want to consider:
- How much hot water your household uses (and how often)
- Whether your home is better suited for gas or electric
- Whether a tank or tankless system fits your needs
- Garage vs. indoor vs. outdoor utility panel placement
- Energy efficiency and monthly operating costs
- How Scottsdale’s hard water affects system lifespan
Why Professional Installation Matters
Water heater installation should be done by professionals. Improper installation with gas connections, electrical wiring, venting, or safety controls can produce dangerous situations, including:
- Gas leaks
- Electrical hazards
- Carbon monoxide risks
You may also experience more frequent shutdowns, earlier system failure, and void your water if you don’t have a professional do the install.
A professional technician will make sure you choose the right size system and make sure it meets all local building codes and state regulations. You also get secure gas and electrical connections, proper airflow and venting, and a full system test to make sure everything’s working right.
George Brazil technicians follow manufacturer standards and safety protocols during every installation. Our goal is to give you a system that works reliably the moment it is installed and continues doing so for years to come.
Water Heater Troubleshooting: Common Problems and Solutions
Here are a few of the most common problems we see, along with expert tips to troubleshoot your hot water system.
Why Is My Water Heater Not Lighting?
When your water heater is not lighting, there are a couple of common reasons, including a problem with:
- Insufficient gas pressure
- Blocked pilot tube
- Dirty flame sensor
- Tripped safety switch
- Faulty gas control valve
Diagnosing and fixing the problem, especially with gas water heaters, should be left to professionals. Gas is combustible, and you need to make sure the job is done safely. This is especially important it you smell gas and hear unusual noises coming from your hot water heater. If that’s the case, stop, turn off the gas, and call for service immediately.
Water Heater Leaking From the Top
If your water heater is leaking from the top, it’s typically a problem with the fittings or connections. Common sources include:
- Loose flex connectors
- Corroded inlet or outlet fittings
- Failing dielectric unions
- Leaking T&P valve discharge near the top
- Internal tank corrosion
You might think a leak at the top is a minor issue, and it can be if you get it fixed. Ignoring it can lead to bigger (and more expensive) problems in the future.
Water Heater Pipe Leak Fix
A water heater pipe leak fix might be as simple as tightening up the fittings, but it may also mean replacing connector lines, joints, or fixing damaged valves. We often see pipe leaks as a result of:
- Corroded copper or steel fittings
- High water pressure causing stress at joints
- Mineral buildup that wears through pipe walls
- Improper installation or poor soldering
If you see water pooling or dripping around your pipes, you should call in a professional for repairs and to stop the problem from getting worse.
Hot Water Heater Relief Valve Is Leaking
A hot water heater relief valve is leaking generally because your tank or tankless water heater in Scottsdale is dealing with water pressure that’s too high, the temperature is at an unsafe level, or the valve itself needs replacement. Some common reasons include:
- High water pressure in your home
- Expansion without a functioning expansion tank
- A valve that’s failing and no longer seals properly
Never plug, cap, or restrict this valve. It is a critical safety component designed to prevent tank explosions.
Why Is My New Hot Water Heater Not Working?
This one’s really frustrating. You’ve just put in a new hot water heater and it’s already not getting the job done. So, why is your new hot water heater not working properly? It’s typically because of component failure or improper installation.
Even new systems can fail if:
- The gas valve is not fully open
- There is air in the gas line
- The circuit breaker was not sized correctly
- The thermostat wiring was installed improperly
- The mixing valve was adjusted too low
- The recirculation system was set incorrectly
- A component is defective
A trained technician can identify the cause quickly and ensure your new system works the way it should.
