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.

John was very knowledgeable and pleasant to work with. Unfortunately, he didnt have the parts i needed so he will be returning in a couple of days to do the actual work. I will update after the work is completed.
Fast and reasonable.
These guys replaced my Water Heater today. Prompt, fair price, easy to work with. 5 Stars is not sufficient to rate their quality
Extremely impressed and satisfied with professionalism and service. A real person always available by phone unlike several competitors I tried to reach. Eloy the tech was the best in all respects.
Friendly, knowledgeable and efficient.
They have done several projects for us and they were done efficiently and well. I highly recommend them for any water service
Fast, reliable. Polite repair people. Fair price.
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
We had a leak in our drip system. Johnny was awesome. He took the time and explained what the problem was and how to get it fixed. He didn't have the part...
Allegiance and Eloy are my "go to" plumbers. Prompt, efficient, cost effective and courteous.
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...
Allegiance has been great. Eloy was perfect. I recommend this company highly and will certainly continue to use them in the future.
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.
Fixed my backyard sprinklers without having to put a whole new system in.
Johnny Gonzales was very professional, courteous, and thorough.
We have used Allegiance Water Services for several years now, and we have not been disappointed. Very professional, quality work, friendly, reliable.
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!
He installed a water softener system and did a great job. He also updated our r/o system. Very professional
Allegiance Water Services are prompt, thorough, and professional. I found them when they did work on my next door neighbor’s irrigation system. When my irrigation started leaking and watering weeds, I called Allegiance Water Systems for a quote and then to schedule repairs. They send text messages and emails with links to track your technician or to call them direct. Invoicing is quick and easy to access via their billing system. You have everything in writing with links to confirm, deny, or modify your service needs.
Lawson was punctual, polite, clean and knowledgeable. He serviced the RO system. Recommended an alarm to detect a leak. Will think about it.
These Guys are awesome! They were on time and on the mark. Service was professional and they did a clean repair. I would definitely recommend them.
Excellent job! Will use them again.
Paul and Allegiance are the best!
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.
Technician patiently walked me through my current setup, identified multiple leaks, and looked to save money by combining and eliminating unneccesay zones.
Lawson with Allegiance Water has done work for us the last few times and he’s very polite and professional and has done great work for us!
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.
Will make sure the job gets done!
Paul is all of the above plus irrigation systems technologically advanced.
I had Eloy come by to repair a water softener system that had failed, as well as replace the filter in the RO system. He was courteous, knowledgeable, responsive, timely, and really knew his stuff.
I love this business. They go the extra mile to make sure their clientele are taken care of. My hot water heater went out on New Years eve and required a part to fix it. The part was unavailable and Rheem the manufacturer was closed until Monday. John Gonzales from Allegient brought out a new unit and installed it, so that I would have hot water for the weekend. This is a great company, and I am glad that I selected them. UPDATE Allegiance is my go to water company. My house is 50 years old now, so I'm glad I have them to call if I have a problem. Rommel Valenzuela came today to service my filtration system. He was nice, professional and did a great job.
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.
Arrived on time , perfectly described a job he'd be doing and provided excellent service , would recommend him to all of my neighbors, did a great job fixing my water heater leak
Excellent service and water quality!!
Josh and the office and service tech Rommel were excellent in every way! Professional, knowledgable service of issues with my water softener.
Would highly recommend. Lawson was very professional.
