Signs You Need Hot Water Heater Replacement
Over time, your hot water heater will experience wear and tear that will affect its performance, efficiency, and lifespan. Most heaters only last between 10-20 years before they need to be replaced. The most obvious sign that you have a problem is a lack of hot water. However, there are usually other warning signs that your water heater is getting old, is less efficient, or isn’t providing enough hot water for your household’s needs. Upgrading to a newer and more efficient heater can make you and your family more comfortable and even lower your water heating costs. Call us now if you notice any of these signs:
- Your hot water is rusty, dirty, cloudy, or full of sediment
- The hot water smells strange
- You don’t get enough hot water for your household’s needs
- The water fluctuates between hot and cold or lukewarm and cold
- It takes a long time for water to heat up
- Your water heater is leaking, or you see a puddle of water near the base
- The hot water faucets have low water pressure
- Your water heater is making strange new noises like rattling, banging, or dripping
- The pilot light won’t light, won’t stay lit, or is orange, yellow, or red
- Your water heater is over 10 years old
- You are paying for frequent repairs
- Your water heating bills are increasing
Choosing the Right Type of Hot Water Heater
We are not limited to replacing conventional storage tank water heaters. We also can upgrade your system to a tankless water heater or hybrid electric water heater. Our friendly, knowledgeable plumbing technicians are happy to answer your questions and help you determine which type of water heater is right for your home:
- Gas Water Heater Replacement – Natural gas water heaters use natural gas to heat water. If you don’t already have gas service to your home, you will need to schedule an inspection and hire a plumber to install gas lines, then sign up for gas service from your local utility company. If you already have a gas hot water heater, you may still need an inspection from your local gas company after replacing it.
- Electric Hot Water Heater Replacement – Electric water heaters use electricity to heat water. They are ideal for homes that don’t have gas hook-ups or in areas where electricity is less expensive than natural gas.
- Storage Tank Water Heater Replacement – A storage tank water heater is the most common type of home water heater. It has a large insulated tank, typically between 30-80 gallons, in which water is heated and stored until you turn on a hot water faucet. They are available in natural gas, propane, and electric models.
- Tankless Water Heater Replacement – A tankless water heater, also called an on-demand water heater, does not store hot water in a tank. Instead, it uses heating coils to heat the water as you need it. They are best for small households and homes that don’t use more than one hot water appliance at the same time. They are available in natural gas or electric models and are highly energy-efficient.

Why Hire an Expert for Water Heater Installation?
Proper installation depends on many factors, including energy or fuel source, local building code requirements, unit location in your home, and safety issues. It’s best to have a qualified plumbing contractor install your new water heater. An improper installation, or a unit that does not match the needs of your household, can cause property damage, safety issues, or higher than necessary gas or electric bills. Our plumbing contractors are factory-trained and certified to install all leading brands of water heaters and ensure safe and proper installation. Allegiance Water Services can also help you determine which type of home water heater is right for you. The lowest-priced unit may be the most expensive to operate and maintain over its lifetime, and it may not provide enough hot water for your household’s daily needs.
Frequently Asked Questions
How Long Does a Water Heater Last?
Most residential tank water heaters last around eight to 12 years, while well-maintained tankless models often reach 15 to 20 years or more. Their actual lifespan depends on factors like water quality, installation, usage, and maintenance. For instance, hard water, high demand, or skipped flushing and anode-rod replacement all speed up corrosion and sediment buildup. Commercial water heaters typically face heavier usage cycles and higher recovery demands, so they may wear out sooner unless they’re built with more robust components and receive strict, scheduled service. In both settings, routine professional maintenance and timely repairs are vital to stretching your water heater’s lifespan and avoiding sudden breakdowns.
Should I Repair or Replace My Water Heater?
You should usually repair your water heater if it’s relatively young, has a good service history, and the problem is minor, like a faulty thermostat, small valve leak, tripped breaker, or worn pilot assembly. When the tank is eight to 12 years old, shows rust on the exterior, leaks from the tank itself, or produces discolored or sandy water, replacement is usually wiser. Frequent repairs, loud rumbling from heavy sediment, or chronic lukewarm showers also signal that money spent on fixes may not pay off. A new, high‑efficiency unit can lower energy bills, improve comfort with more reliable hot water, and offer longer, more predictable performance. Allegiance Water Services’ team will gladly assess your water heater and advise you on the better choice between repairs and replacement.
How Long Does Water Heater Replacement Take?
A straightforward residential water heater replacement often takes about two to four hours from shutoff to hot water restoration, assuming a plumber has easy access and compatible connections to work with. The timeline stretches when the installer must upgrade gas lines, install new venting, add an expansion tank, or bring old plumbing and electrical work up to current code. Tight crawl spaces, stairs, or rooftop access also slow things down. Commercial water heater service is usually more complex because units are larger, may be installed in banks, and often tie into recirculation systems or building controls. Coordinating shutdowns, safety checks, and inspections typically adds time, but helps businesses avoid repeated interruptions.
What Are the Signs of a Failing Water Heater?
A failing water heater usually gives you several warnings. You might notice water that turns lukewarm quickly, inconsistent temperatures, or long waits for the shower to heat up. Rumbling, popping, or banging sounds often mean sediment has hardened inside the tank. Rusty or cloudy water, metallic-tasting hot water, or moisture pooling around the base indicate internal corrosion or small leaks that can suddenly worsen. A water heater unit that needs frequent repairs or is already a decade old is likely near the end of its life. Because these symptoms can overlap, you need a professional like Allegiance Water Services to safely diagnose the issue and recommend a reliable new model if replacement makes the most sense.

Overall Rating
Had a hot water heater replaced today; Lawson did a fantastic job. The workmanship is very professional. Lawson was on time and did exactly what he said he was going to do.
Would highly recommend. Lawson was very professional.
They answered the phone (after several other business didnt) and came right out to do the estimate and complete the work. Quality is good. Will call next time I need sprinkler/landscaping work.
After 5 years we had water softener , we found out we use soft water for our pool and watering the plants in our back yard , so I called this company they responded fast and the next day they sent their technician Ruben . After we agreed on his estimate , he came the next day. He did awesome job on separating our soft water. Ruben was knowledgeable, fast and reliable. I am so happy with his work and recommend him and this company to everyone.
Fast, reliable. Polite repair people. Fair price.
I had an exceptional experience with Allegiance today. My old gas water heater needs to be replaced. I called Allegiance yesterday and discussed with David who is very knowledgeable, transparent and told me pros and cons among the different water heaters. I decided to go with 50 gallon Bradford White water heater. Ruben came in next day and clearly explained to me what is the process. He is excellent, very skillful and told me how to maintain it. He cleaned everything afterwards. I am very happy with their services and will call Allegiance for my plumbing issues for sure. Ruben from Allegiance Water Services did an excellent job again today. I had water hammer issue for a couple of months and my pipes coming out the main pipe weren't connected right by a previous plumber. The irrigation system controller needs to be replaced as well And it is now upgraded to an enabling phone control unit. Ruben did an excellent job on replacing the unit and repiping everything. It only took him an hour and they work great! Ruben is very experienced, knowledgeable and efficient. It wouldn't go wrong for Ruben to do your plumbing jobs.
We have used Allegiance Water Services for several years now, and we have not been disappointed. Very professional, quality work, friendly, reliable.
Allegiance and Eloy are my "go to" plumbers. Prompt, efficient, cost effective and courteous.
Excellent communication. Reliable.
He was wonderfully informative and polite. Educating me on my irrigation system, as I'm from Michigan and very unfamiliar with them.
Paul came today to check my Rain Bird system controller. I have worked with him during my new irrigation installation project at the beginning of this year. I was extremely pleased with the outcome then and again today. I specifically requested him for today’s job. As always, he offered excellent, professional service, knowledgeable, courteous and friendly. I would refer him and Allegiance Water Service to my friends with high remarks.
I was in a panic when my sprinklers started making loud noises at 5:30am. I called Allegiance water and was able to get a service rep out the next day. They...
Great company. We would highly recommend them. Courteous, professional, fast response time. Very reasonable rates. This is the third time we have used their services and have been very happy every time.
Paul is all of the above plus irrigation systems technologically advanced.
He installed a water softener system and did a great job. He also updated our r/o system. Very professional
John was on time and professional. He fixed the leak in my backyard system and tested it to make sure no further leaks. He also checked the front yard and found an additional leak that I hadn’t noticed and also fixed it in the same trip. Super happy with the great service and will definitely call these guys again for future plumbing repairs outdoors and indoor.
Excellent service. Rommel was very professional. I will call on them again. Marc C.
Very smooth transaction! One phone call got the osmosis and softner system scheduled and an experienced technician came and installed both within 2 hours! Great experience. Thank you!
Looking into my options as soon as I hear back about my options
Lawson was punctual, polite, clean and knowledgeable. He serviced the RO system. Recommended an alarm to detect a leak. Will think about it.
Very prompt service and were there at scheduled times. Both tecs that have been here, Dan and John, were outstanding. Very professional staff including Josh. Pricing is reasonable. I would highly recommend this company.
John was extremely professional and courteous explaining in detail the problems with my irrigation system. He made the repairs and added recommendations as well. He was the best! I highly recommend! Pull
Allegiance is fantastic. Lawson in particular is a total professional. Super knowledgeable, trustworthy, and efficient. Diagnosed our crazy irrigation issues and came up with a cost effective solution.
Annual service on RO water system. Rommel was friendly, fast and professional.
Great company! My water heater and water softener both decided it would be best to stop working on the same day. Allegiance came out and gave me a quote for both and their price was great. I feel like they were really interested in helping me.
Fast and reasonable.
Excellent service
Will make sure the job gets done!
Allegiance Water Services sent a repair man to fix a broken sprinkler head.. He was courteous, pleasant and well informed. He fixed the head and checked to be sure the whole system was working again correctly. I appreciated his service. Thank you
Had an issue with my sprinkler system, something failed and I had a big wet spot on the side of my house. Called in and was helped with instructions on how to turn off the sprinkler side so no water would go to it until a repair could be scheduled. Paul comes out and shows me the problem, we set a time and he fixes all of that, THEN while testing, just waltzes into the spraying sprinklers and dials in where the water SHOULD have been spraying, like " oh, that's the wrong direction to spray for this area..." Then he programs the whole thing to fix my already mediocre lawn and bushes, told me what to do to improve my lawn through yard care and got into his car with soaking pants and thanked ME! 10/10.
Lawson Key was very professional, respectful and kind. He did a great and solid job of installing a new faucet for our water filtration system!
