Common Water Heater Repairs Our Pro Plumbers Deal With

Water heaters work hard behind the scenes, so it’s no surprise they run into trouble now and then. Our professional plumbers in Ontario, CA, tackle a variety of water heater problems every day. Here are some of the most common repairs we perform:

Leaky Tanks

A leaky tank is more than just a nuisance—it can cause serious water damage if ignored. Often, this is due to corrosion or cracks in the tank itself. In many cases, replacing the tank is the safest and most cost-effective solution.

No Hot Water

No hot water? That’s a big red flag. This issue could stem from a faulty thermostat, a broken heating element, or even a disconnected power source. Our techs will inspect your system thoroughly to find the exact culprit and get your water heating again fast.

Low Water Pressure

Low water pressure from your hot water taps can point to sediment buildup inside the tank or clogged pipes. We’ll flush the system and clean out any debris, restoring strong, steady water flow throughout your home.

Rust-Colored Water

Seeing rust-colored water when you turn on the hot tap? That’s usually a sign of corrosion either in your tank or pipes. We’ll determine whether the tank’s anode rod needs replacing or if you’re due for a water heater replacement.

Strange Noises

Banging, popping, or rumbling sounds from your water heater usually mean there’s a layer of hardened sediment at the bottom of the tank. Left unchecked, it can cause overheating or damage. We’ll flush and clean your unit to keep it running smoothly.

Pilot Light Won’t Stay Lit (Gas Models)

If your gas water heater’s pilot light keeps going out, it might be due to a faulty thermocouple, gas valve, or even a draft. Our experienced plumbers can troubleshoot the issue and safely restore your hot water heater’s function.

Whether it’s a quick fix or something more complex, our Ontario-based plumbing team is here to make water heater repairs stress-free. We’ve got the tools, skills, and know-how to tackle any issue—so you don’t have to go a day without hot water.

Our Water Heater Installation Services in Ontario, CA

If your current water heater is on its last leg or you’re simply ready for an upgrade, we’ve got you covered. Our water heater installation services in Ontario, CA are designed to make the whole process smooth and hassle-free. We help you choose the right unit for your needs—whether it’s a traditional tank, energy-saving electric model, or high-efficiency tankless water heater—and make sure it’s installed to the highest standard. You can count on our team for dependable, professional service from start to finish.

The Installation Process – What to Expect

When you book an installation with us, we start with an in-home consultation to evaluate your needs, space, and budget. Then we help you select the best model—gas or electric, tank or tankless—and schedule a convenient time for the work. Our licensed plumbers will remove your old unit, prep the area, and install the new water heater safely and up to code. We test everything thoroughly and clean up afterward, leaving your home better than we found it.

How Long Does It Take to Install a Water Heater?

In most cases, a standard water heater installation in Ontario, CA takes about 2–4 hours. Tankless units may take a bit longer due to the additional plumbing and electrical work involved. Rest assured, we work efficiently without cutting corners, so you’ll be enjoying hot showers again in no time.

Which Type of Water Heater Is the Best for Me?

That depends on your household size, usage patterns, and budget. If you’re after affordability and simplicity, a traditional tank-style heater could do the trick. Larger families who need more hot water on demand might love the convenience of a tankless water heater. Our team will walk you through the pros and cons of each option and help you choose a system that’s perfect for your home and lifestyle.

We Also Offer Water Heater Maintenance in Ontario, CA

Regular upkeep keeps your hot water heater running like a champ and helps avoid those dreaded cold showers (or worse—water leaks!).

For gas water heaters, we also check the burner and gas connections for safety. With electric water heaters, we’ll inspect wiring and heating elements. It’s all about catching minor issues before they become major headaches.

We recommend annual checkups to extend your unit’s lifespan and maintain energy efficiency. Whether you have an older tank or a newer tankless model, our team will help you keep it in top shape with honest advice and affordable service.

Thousands of Happy Customers

Was very happy with the quick response to my call for help. It was a very good experience even though it was a stressful situation. They worked with me and were empathetic to my problem and my limitations. They were very thorough in explaining the situation and what needed to be done, explaining and showing me the problem. Once it was decided what I had to do they were quick to get to work and completed the job in a very timely manner. All in all it was a stressful but good experience

– Susan C.

All Pro was awesome we called and they came the same day when our shower drain was leaking into our downstairs ceiling…..the service person was so nice and was very fast and very professional. The price was very reasonable and affordable. They did an outstanding job and we would recommend this company for all your servicing needs. This is the second time using this company, the first was for our water heater and they replaced it fast and very affordable the same day. They came at around 5 and was here until around 9 fixing not only our leaking shower drain but our water pressure value needed to be replaced. They did both and I do not think we would have gotten a better deal or a nicer person to come and do the repairs. All Pro is definitely the people we will be calling for all our plumbing, heating and air conditioning needs from now on.

– Pamela M.

They came to our rescue on January 8, 2018. we had a clogged toilet that overflowed all the way to the downstairs bathroom it was a horrific scene that day. That is when we decided to call All Pro Plumbing. Talked to a nice lady on the phone gave her our info and told us would call back to ensure us someone would come out to help. Within minutes gave us a response time and told us someone will be there within the hour. Sure enough that is when they showed up and quickly diagnosed the problem, went to work, and unclogged whatever was in there that needed to be unclogged. They were efficient, respectful, and professional. They also checkout out other things to make sure that toilet was working fine before they left. Great customer service!

– Vincent M.

Gary was absolutely amazing today. He was friendly, knowledgeable! It seemed a little pricey but our problem needed to be addressed immediately. Great customer service. I would definitely recommend!

– Danielle O.

I would recommend ALL PRO Plumbing to anyone that is looking for good professional service. They installed a sink and garbage disposal for me and did a great job. Their response time is quick. Always either the same day, or the next day

What Are the Most Common Water Heater Issues?

When you are experiencing problems with your water heater, you will want to make sure the issue is quickly resolved to limit the disruption to your day and reduce any potential damage from the problem.

Some of the most common issues we see as a water heater repair company include:

  • Thermostat Issues: The thermostat controls the water heater. If this component malfunctions, you may lose control of the heating or cooling capacity of the unit.
  • Electrical Issues: Modern water heaters rely on electrical sensors and components to function properly. If these parts break or stop working, you may be left with no hot water at all.
  • Physical Damage: Cracks, dents, and leaks in the water tank require immediate assistance from a professional.

You can count on our professional team to provide water heater services in Ontario that will solve your problems and help prevent future water heater damage.

How Long Does a Hot Water Heater Last?

At All Pro Cooling, Heating, Plumbing & Electrical, we understand the significance of a dependable hot water heater in your daily routine. Understanding the lifespan of your hot water heater aids in planning for its eventual replacement and preventing unexpected disruptions.

While the exact duration can vary due to factors such as usage, maintenance, and water quality, here’s a general overview of how long different types of hot water heaters typically endure:

Traditional Tank Water Heaters

Conventional tank water heaters, which store and heat water in a tank, usually last around 10 to 15 years. Routine maintenance, such as flushing the tank to eliminate sediment, can prolong their lifespan.

Tankless Water Heaters

Tankless water heaters, also known as on-demand water heaters, boast a lengthier lifespan compared to traditional tanks. They can endure approximately 20 years or more. Their efficient design heats water only when required, minimizing wear and tear.

Factors That Determine the Lifespan of Your Water Heater

Several factors can impact your hot water heater’s longevity:

  • Maintenance: Regular upkeep, including tank flushing, leak checks, and anode rod replacement, can extend your water heater’s lifespan.
  • Water Quality: Hard water containing high mineral levels might lead to sediment buildup and corrosion, potentially shortening its life.
  • Usage: Increased demand and frequent use can strain the water heater, affecting its durability.
  • Installation Quality: Proper installation by experienced professionals ensures efficient and safe operation, contributing to an extended lifespan.

If your hot water heater is approaching its life expectancy or displaying signs of trouble, it’s prudent to consider a replacement. Our team at All Pro Cooling, Heating, Plumbing & Electrical can evaluate your water heater’s condition, provide expert guidance, and suggest suitable replacement options.

The Benefits of a Tankless Water Heater Installation

If you are considering installing a new water heater, think about consulting our Ontario tankless water heater professionals.

Some of the most significant benefits of tankless water heater installation service include:

  • Savings – Since the tankless water heater uses less energy to operate than a traditional tank water heater, that means it will cost you less off your monthly utility bill. If that sounds like something that’s attractive to you, contact our Ontario tankless water heater specialists today.

  • Reduced carbon footprint – Since tankless water heaters only heat up the water you need, there isn’t any wasted heating going on which will significantly reduce your carbon footprint.

  • Unlimited hot water – Tankless water heaters are also known as on-demand water heaters because they will heat up your water as you go, always making sure you have hot water.

  • Spend less on water heater repair – Fewer parts in the unit result in fewer things that can go wrong. Still should anything happen our Ontario tankless water heater repair specialists will always be happy to look at your unit.

  • Spend less on water heater replacement – These units also require tankless water heater replacement less frequently than traditional units because they last almost twice as long as traditional tank units.
