Signs You Need Hot Water Heater Repairs
To help you diagnose issues with your system, we have created a list of the main signs your water heater requires professional repair services.
- Leaky Hot Water Heater: A water heater is built to keep water contained within the tank and flow seamlessly through your plumbing. A leak not only disrupts this but it can also cause costly water damage to your home.
- Inconsistent Water Temperatures: Water coming from your shower head and faucets should be a consistent temperature. If your water suddenly shifts from hot to cold or vice versa without turning the handle, this could be a sign of a bigger problem with your water heater.
- Sudden Low Water Pressure: Some homes have lower water pressure than others. However, a sudden drop in your water pressure is a red flag that something could be wrong with your water heater. Day & Night provides trustworthy water heater repair services and will find the root of the issue to create a custom solution to meet your needs.
- Smelly Water: The water coming from your shower head and sinks should be crystal clear and odor-free. Rust-colored or cloudy water could indicate the presence of contaminants or debris in your water. There could be cracks or rust in your water heater tank polluting the water in your home, which would require a professional plumber to address these concerns promptly.
- Sudden, Loud Noises: Other than the occasional rush of water when you run an appliance, your water heater should be pretty quiet. If you hear sudden noises from your heater, such as bangs or clanks, you should get in touch with a plumbing expert at Day & Night to find the cause of the noise.
- You Run Out of Hot Water Quickly: Water heaters with tanks store warm water to use later, so you can eventually run out of hot water. However, if you notice you are frequently running out of hot water or your hot water does not last very long, it could point to an issue with your water heater.

Water Heater Repairs vs. Water Heater Replacements
When your water heater isn’t working properly, how do you decide between a repair and a full replacement? Repairs are ideal for addressing minor issues, offering a quick and cost-effective solution that can extend the life of your unit when done correctly.
However, significant damage or frequent breakdowns might signal the need for a replacement. While repairs can temporarily resolve problems, water heaters naturally wear down over time. If you’re facing repeated issues, investing in a new unit could provide a more reliable and cost-efficient solution in the long run.

Top Types of Water Heater Problems Our Expert Plumbers Can Fix in Your Home
When talking about water heater problems, there are a handful of issues you could potentially be dealing with. From leaky units to unusual sounds, our team is equipped to handle it all. We’re ready to get to work repairing some of the most common types of water heater problems, including:
No Hot Water
Your faucets and shower heads have hot and cold water connections, and you expect your water to get warm when you turn on the hot water connection. If you turn the handle to ‘hot’ but the water from your tap is still ice cold, this can indicate a problem with your water heater.
Our water heater repair services in Phoenix, AZ, will get to the root of the problem and get your hot water flowing again.
Minimal Hot Water
Sometimes, you don’t lose your hot water entirely. You may still notice your water getting a little warmer, but it’s not as hot as you would like. You could also find yourself running out of hot water faster than normal if you have a traditional tank water heater, which can mean something is wrong with your unit.
Our skilled plumbers will thoroughly inspect your unit, diagnose the issue, and provide a fast, reliable repair—ensuring you have hot water exactly when you need it.
Water Is too Hot
If turning your sink or shower handle to ‘warm’ results in scalding hot water, it’s time to call in the professionals. An unregulated water temperature can lead to high utility bills and pose a serious risk of burns or scalds.
Our expert team can safely adjust your water heater to ensure it’s functioning properly, keeping you and your loved ones safe while providing the comfort you expect from your baths and showers.
Sediment Buildup
Homeowners know all too well that the local water is filled with minerals and other sediment that can leave residue on every surface it touches. Not only does this hard water leave a buildup on your shower curtains and hair, but it can also build up inside your water heater.
If you have a tank-style water heater, sediment buildup inside the storage tank can lead to corrosion and eventually cause leaks. Fortunately, our staff of local plumbers offer extensive water heater repair services in Chandler, Arizona and will flush your tank to remove mineral deposits and help extend its lifespan.
If damage has already occurred, we’ll assess the situation and provide the necessary repairs to keep your system running efficiently.
Leaking Water Heater
No homeowner wants to find a puddle of water around their water heater. This can indicate a problem with the tank, a connection or valve, or any other primary component.
No matter how small, an untreated leak can lead to extensive water damage and costly repairs. Our team will make sure to take care of this to ensure no further damage can occur.
Discolored Water
When you turn on your faucet or shower head, you expect to see crystal-clear water pouring out. Finding brown, cloudy, or rust-colored water from your fixtures can be alarming, and in some cases, it can be harmful. Dirt, minerals, and other contaminants can discolor your water and make the thought of taking a shower or washing the dishes unbearable.
Our team provides dependable water heater repair services for houses in Glendale, Arizona and will inspect your system to determine the source of the discolored water. Whether it’s a dirty water heater tank or a cracked water line, we will repair it to the fullest.


Is Your Water Heater Making Strange Noises?
A water heater that’s functioning properly should be nearly silent except for maybe a faint buzzing noise. Loud noises that start suddenly can mean something is wrong with your unit.
Different sounds can point to specific problems, so keep your ears open for any of these common noises that indicate your water heater may need some attention:
Banging and Rumbling Noises
Crackling Sounds
You may hear crackling noises from your water heater, which is common for electric-powered units and usually nothing to worry about. However, if these noises persist, there may be sediment buildup or something blocking the heating element, which would require a professional inspection.
If your water heater runs on gas or oil, crackling noises are more likely caused by moisture buildup. Contact our licensed plumbers if you suspect water is pooling around your unit. Even if your water heater isn’t electric, it still relies on electricity to operate. Water exposure to electrical components can be dangerous, so it’s important to address potential issues quickly.
Ticking Noises
A ticking noise can make it feel like you’re on the clock, counting down to a water heater failure. However, the cause is often not that severe. Ticking sounds are typically linked to changes in water pressure or thermal expansion.
While this noise is usually harmless, if the ticking gets louder or turns into banging, it could be due to a loose connection, sediment buildup, or a faulty heating component, which would require professional support. Luckily, our team of expert plumbers offer dependable hot water heater repair services in Phoenix, Arizona and will work with you to fix loose connections in your system.
Screeching and Whistling Sounds
There are valves within your water heater that release water and steam to relieve excess pressure. This process of releasing hot water and steam can create a whistling or screeching sound as it forces its way through the valves, which often indicates a significant pressure issue.
There could be a number of reasons for this—including faulty valves and excessive pressure buildup. The temperature and pressure valve (T&P valve) is a critical safety component—so if you hear screeching noises from your water heater, it must be dealt with promptly.
Popping Noises
The buildup of mineral deposits (calcium and magnesium) in your water heater can create a popping noise when water trapped within the sediment turns into steam. This sediment comes from hard water leaving behind mineral deposits, which accumulate around the heating element or at the bottom of the tank. Over time, this buildup can reduce efficiency and lead to louder noises.
Regular flushing of the water heater can help prevent sediment-related issues. You may also want to replace the anode rod—a part that helps reduce sediment and bacteria buildup. Since Arizona is known for having hard water, installing a water softener system can also help minimize rust and sediment issues.
Traditional Water Heater Components
- Pressure Relief Valve – The pressure relief valve is an important safety factor in tank water heaters that allows pressure in the tank to be released safely if it becomes too high. If the valve is not working or malfunctions on either gas or electric water heaters, it could cause an explosion.
- Anode Rod – The anode rod is designed to attract minerals in gas or electric water heaters that could cause corrosion in the tank. We recommend replacing it every five years.
- Tank Flush – With hard water, sediment can build up in tanks over time and cause a popping noise in the water heater. Flushing the reservoir each year will flush out the minerals to prevent corrosion.
- Pilot Light (Gas Only) – We will visually check your pilot light and clean when necessary.
Tankless Water Heater Components
- Heater Flush – Even though there is no reservoir on a tankless heater, maintenance is still required to keep minerals from building up on the pipes and heating element.
- Air Intake Filter – Air should be able to flow freely through the unit. If debris is clogging your air intake filter, it could prevent your unit from working efficiently.
Water Heater Maintenance Tips
- Keep Up With Maintenance: While it may feel like a chore, routine water heater maintenance improves the overall lifespan of your water heater and keeps it working efficiently. Skipping maintenance appointments can lead to hidden issues popping up later and leading to costly repairs.
- Flush Your Water Heater: Tanked water heaters are susceptible to mineral buildups in the tank, and these cause cracks and rust to form. To help prevent this mineral buildup, flush your water heater regularly.
- Check the Temperature Pressure Relief Valve: The pressure relief valve makes sure excess pressure does not build up in your water heater, leading to an explosion and serious damage. Checking this valve regularly can protect your family and prevent excessive wear and tear on your water heater.
- Lower Your Water Heater Temperature: Setting your water heater to a lower temperature means it doesn’t have to work as hard to heat the water, which can make your unit more energy-efficient and improve efficiency.
- Replace the Air Intake Filter: The air intake on your water heater allows for proper airflow and prevents your unit from overheating. Replacing the filter regularly can keep your unit clean and make sure it is working properly.
- Replace the Anode Rod: The anode rod in your water heater prevents the tank from corroding due to mineral buildups. You should replace it regularly to help prevent tank corrosion and keep your water heater running well for many years to come.
