City Of El Cajon Water Heater Codes

We work very closely with the City of El Cajon to make sure that all the work we do is up to the current building code. Most recently, we asked the city inspector this question:

Where is an acceptable location to terminate the Temperature/Pressure (T&P) line?

We received this answer:

To the exterior only! This means that all T&P lines must run to the outside of the home.

For more information about the building codes for the City of El Cajon, you can either call 211 or visit their website at: https://www.cityofelcajon.us/your-government/departments/community-development/code-compliance

I called the company because I thought I needed a new water heater. I had met with two companies before and gotten quotes before finding water heaters only. I met with Thomas a very personable young man who noticed the heater was showing an error message that indicated something just needed cleaning. I hadn't noticed it before, and no other company said anything about it. So, we agreed that he would just clean it instead of replacing it and he did, and I was very happy. Needless to say, I will be calling him back when it finally does fail. Great job! I definitely appreciated his competence and honesty. I recommend you ask for Thomas.

Our tech was Alexis; he called an hour prior to coming out to let us know when he'd arrive. He explained the work to us, went over the estimate and answered all our questions about the installation. He completed the job very timely and left the work area very clean. Overall we are very satisfied with Alexis and Water Heaters only for their quick response to our problem. Would use them again if needed or recommend to others.

Had a great experience with the technician. John Burns did an excellent job of explaining the work to be done and what the cost would include. He was very professional while installing the water heater. Once the water heater was installed, he did a nice job of explaining how to adjust the temperature and how to shut down the gas if needed and showed me where the important valves were. Would recommend Water Heaters Only to my friends.

We just had a new Water Heater installed yesterday by Thomas who was amazing. He explained everything in detail, very friendly easy to communicate with. I love my new Water Heater. I have recommended them to my brother and will recommend to anyone who is needing repair or a new Water Heater. Thank you for all your help.

I was given a 4 hour time window for the installer (Thomas B) and he called me shortly after 9 and notified me that he would have to pick up the water heater from the warehouse (30 gallon heaters were not normally kept in inventory). He called again when he he picked it up and gave me the time he expected to arrive. Once he arrived he inspected the old heater (24 years old) located in the crawl space under the house, gave me a quote and told me that more more earthquake reinforcement should be put in for safety reasons. I accepted the quote. He drained and removed the old heater, installed the new one, built additional reinforcement and tested the system for functionality and leaks.He was courteous, conscientious and friendly

Justin was our Technician. He arrived punctually and throughout the installation, he was outstanding: super courteous, very knowledgeable and communicative. Once done, he was meticulous in his clean-up and then gave us a full explanation of everything he had done. In our estimation, he deserves a 10-Star Rating!!!!

Baron Chen

01:32 14 Feb 24

Long story short, fantastic service provided by Water Heaters Only and technician Thomas B. If anyone is living in San Diego I would highly recommend Thomas B. as your next technician because of his high degree of knowledge, the meticulous work he provides, and the honest craftsmanship. My water heater flame went out and when I tried the pilot re-lit the flame would not stay on. After considering replacing the storage water heater, Thomas B. made a last-ditch effort to replace the thermocouple and to our luck, it worked! The flame stood strong and Thomas even waited over a couple hours to ensure the flame did not fade. Overall, I am very pleased with the quality work provided by the technician and the professionalism of Water Heaters Only. Will definitely call back if needing a replacement water heater.

Great experience with this company! I called on a late Friday afternoon and had someone at my house at 10am the next day. Justin was super polite and professional. He clearly explained everything to me, told me the cost of the job, and in 2 1/2 hours I had a new working water heater! The company worked with me regarding payment, and the whole process couldn't have been smoother. Thank you from my whole family!

This company and their Technician, Damien, were great to work with and I would not hesitate to call them again in the future. They provided top quality products and service, and I have confidence in the high-grade water heater they installed. Damien went above and beyond to add earthquake safety braces and to replace corroded water line connections.

I recently had the pleasure of using the services of Water Heaters Only, Inc. for the installation of a new water heater in my home, and I must say that I am extremely impressed with their outstanding service. From start to finish, the entire process was flawless and exceeded my expectations.The installation itself was done with precision and skill. Damien, who was the technician, was well-prepared and had all the necessary tools and equipment. Damien worked efficiently and meticulously, ensuring that everything was installed correctly and up to code. He paid attention to even the smallest details, such as properly sealing all connections and checking for any potential leaks.I’m also impressed with the quality of the water heater itself. Water Heaters Only, Inc. recommended/uses Bradford White water heater which is of high-quality and energy-efficient that suits my needs perfectly. I have noticed a significant improvement in the hot water supply and overall efficiency since the installation.Overall, I would highly recommend Water Heaters Only, Inc. for any water heater installation needs. Their professionalism, expertise, and excellent customer service truly set them apart. I am extremely satisfied with their work and will be using their services again in the future.Thank you, Damien, for the outstanding water heater installation!Sincerely,Milton MartinezLa Mesa, CA 91941

Would highly recommend Water Heaters Only and our technician Justin. Justin was professional, courteous, punctual, and respectful. He answered all our questions, never felt like we were getting the run around. His workmanship looks great and even cleaned up after himself sweeping out our garage. Would definitely use Water Heaters Only again in the future and will be recommending them and Justin to all our friends and family.

21:50 24 Dec 23

We were astonished to receive same-day service and an excellent price. Our service tech Thomas was very knowledgeable and took great pride in his work, which is rare to find these days. We received a top-rated Bradford White water heater which is not available at the big box stores. Highly recommend this company.

After waiting a day for someone to come out, the technician obviously did not want to do the job. First they had an issue with the proximity of my washer and dryer. Then they proceeded to quote saying it was going to much higher cost due to the install and finally said they could not do it until I “repaired” my dry wall claiming they couldn’t strap it in properly due to a crack - except the strap is going into the stud on my wall, not the drywall. They changed me $65.00 for my trouble. While trying to find a drywall repair- I kept running into the issue of the water heater being in the way. Called to see if they would at least come back to remove the old water heater - they could for another $400 which would be in addition to the quote in place. Ended up finding a plumber who charged me almost $1000 less than their quote and did not require me to spend another $700+ in unnecessary repairs

Wow! I have a water heater that the pilot light won't light. I called 'Water Heaters Only' and the guy basically didn't want the business.I told him that it was a RHEEM water heater and he couldn't talk enough about how bad RHEEM products are. He said that they (RHEEM) is known for it's "defective" products. He stated that they could not get the required parts from RHEEM. I then contacted a different company.. I now have an appointment in 2 hours.I would NOT recommend 'Water Heaters Only'!

I can't say enough about Justin, our tech, and the value of the service. As a matter of uncanny timing our old water heater started leaking all over our garage a week after moving back into our home. We were displaced due to a major plumbing leak flooding two floors of our townhome. I called a few places but found Water Heaters via Google. The main reason I contacted them was because one review said they were 40% less than every other estimate. I had been quoted nearly 5k for a replacement and install by other companies and the wallet was feeling a little worse for wear. After speaking with a very helpful phone rep (sorry that I don't remember her name), I made a same day appointment. Justin our tech called me and asked if he could come earlier. Justin was professional and was happy to accommodate our kid and dog chaos. Justin gave us a complete rundown of the job and an educated guess on the timing of the service. We were able to get the kids out of the house and trust him to do his work. When we returned Justin had finished his work which included replacing the valves and copper tubing to the water heater. All in all we spent almost half the amount of the other estimates and got more done than we expected. I have already recommended the company to a coworker and my wife has done so to. Very thankful for this experience after having to deal our very stressful previous flood and all the insurance and plumbing hassles.

They did a good job replacing our old water heater back then and it lasted for 16 years. Last night after 16 years our water heater broke, they send technician Justin who did a very good job. He was professional, thorough, efficient, courteous and a quality of job well done. I will definitely recommend Water Heaters Only to my friends, relatives, seniors and significant others. Thank you for your satisfaction service!

Justin arrived on time. He reviewed my history of water temperature loss, inspected the water heater, verified the age of the existing tank and provided an estimate to replace that was 40% less than two previous estimates from local competitors.He removed the old system, upgraded all associated parts to meet code and installed a new water heater efficiently with a very professional mechanics. Clean up was spotless....and he is really friendly guy!

John also made sure to clean up after and left the space even cleaner than it was before He arrived.What really stood out to me, however, was the affordability of the service.

My 30 year old water heater that came with the house started a small leak from the bottom so I knew it was time to go. I emailed Water Heaters Only and got an appointment with Danny (182785) who was very professional and knowledgeable. He answered every question possible that I could have for a water heater replacement and went above and beyond for customer service. Hopefully we won't need to call Water Heaters Only anytime soon but if we do I know Danny will be there to resolve it.

Ester Banayo

03:08 28 Sep 22

Danny 177157 came on time and immediately checked the tank and he explained to me everything and all possible options and I picked to replace it after knowing that it was mire than 10 years old. He immediately worked on it, and he did it so well and he made sure that everything is properly and correctly attached. He's so patient and after several hours the water heater was properly attached and secured. He's so efficient, kind and courteous. He's so patient answering all my questions because I'm new to it and after he's done he taught me what to do just in case it leaked again and there's to one that can come right away. Thank you so much for your help and thank you Water Heaters Only for sending someone who's responsible and knows what he's doing. Job well done.

04:20 22 Sep 22

This is our second time using Water Heaters Only. They responded quickly and sent a technician out the next day. Clayton Young did an outstanding job and is an absolute pleasure to work with. He went above and beyond to replace our leaking water heater and bring everything up to code. He kept me posted on his arrival time, explain everything he was doing, and even let me record a video of how to relight the pilot. I would definitely ask for him again should we have water heater issues.

Donald Pier

John B arrived about halfway within the time window given on the phone, explained everything to me, answered all my questions, and then got right to work removing my old leaking water heater and installing a new one. It only took a couple hours from start to finish, and he cleaned the area up better than he found it. I was pleased with the promptness, the work, and the price, and found John to be knowledgeable and efficient, as well as very friendly and personable. All in all, a good experience, and I would recommend him and this company. Thank you.

My husband is very handy around the house and on the rare occasion we hire someone to do some work or install something, he typically complains about the shoddy workmanship (he is a perfectionist). When we had our water heater installed, he commented that the installation was very professional. We have been married 24 years and I think that’s the first time I’ve heard him say that… so kudos and plaudits to Water Heaters Only— that’s quite a feather in your cap!

Tonya Brown

03:01 22 Jul 22

Justin arrived promptly during the given time frame. He didn't have what he needed based on our wrong description but was fast getting the right water heater and back to do the work. He is very knowledgable, professional, and his work is very clean. We couldn't have asked for a better person! So glad we were lucky enough to get him. Thanks for excellent workmanship! T&C

Al Peterson

John B. removed my leaking water heater and installed a new one for me. He arrived on time, provided a quote in the range I had been told on the phone, and did an excellent job with the install.

Justin was very courteous. Answered all my questions. He was very clear in pricing what I needed. Far more helpful, clear and fair than any of the other companies I contacted. Water Heaters Only was very responsive - the early bird got the worm.

Sean Lynch

20:06 06 May 22

Justin came to my house, knew exactly what he was doing, and performed a very professional installation. No fuss, no dealing with unreliable contractors, no back and forth. I called, paid the amount quoted, and got a perfectly installed new water heater. If you’ve ever tried to find a good contractor you know why this is completely mind blowing.

Jeff Albrecht

22:14 24 Mar 22

I was pleased that WHO was able to install a new water heater on the day I called. Unlike a couple of other companies I telephoned they were kind enough to inquire about my old heater and quote me a price for replacement. John B was the technician assigned to my job. He was friendly and professional, and I would heartily recommend him for anyone considering such work in the future.

Chelsea Addison

12:08 18 Mar 22

When they say open 24 hours they mean it! I needed a new water heater and work crazy hours so it’s difficult for me to call businesses during normal working hours so when I stumbled across Water Heaters Only and saw that they take calls 24/7 I thought that’s exactly who I need. I hesitated calling at 11:00 at night thinking it would be an answering service who wouldn’t really be able to answer my questions or schedule my appointment - I was definitely wrong! The rep that answered the phone was friendly, helpful, knowledgeable, and was able to schedule my install for the next morning! Total shocker! I then received a call at 7:45 AM to confirm the installation time and to let me know that the installer would be coming from North County so he wouldn’t be here until 10 AM which was fine with me because I was still sleeping, ha ha. Clayton arrived on time and completely prepared for my installation. He was friendly, easy to talk to, and got right to work. He was efficient and had everything removed, installed, and ready to use in less than 2 hours. Highly recommend and appreciate how smoothly the installation was done.

The representative, Justin appeared at the beginning of the 4 hour window and was courteous and help me to understand the new codes & regulations that would be needed to be completed before he installed in the water heater. He did a job that appeared well done and in a very timely manner. I highly recommend this company if you want fast, efficient service.

Justin replaced my failing water heater with a new one. He was informative, efficient with his time, his work was clean, no mess, installation and piping looks great. Heck he left my garage better than I had it. Justin answered every question I had. I couldn't be happier with Water Heats Only as well as with the professionalism that Justin showed. I will for sure be recommending Water Heaters Only to friends and family

Chris Lindahl

01:29 23 Dec 21

Justin was great. My water heater broke during the night and was leaking. He came out same day to install a new one. Updated the gas line, water supply, sediment trap, and expansion tank. Looks so much better than the old one. He worked quick and was professional and friendly. Would definitely recommend.

Helen Cohn

19:36 28 Nov 21

Highly recommend! Friday morning after Thanksgiving and water heater died. Called WHO and got scheduled for the next afternoon. John B called to let me know he was on his way, showed up right on time, looked at our old setup and immediately said “no problem”. Even though our old water heater still had water in it. Even though it’s kind of an awkward location. No problem. John was meticulous, obviously knew what he was doing, and explained everything I asked. Totally professional. All done for a fair price, and on a holiday weekend! WHO goes in my list of companies to call, companies to recommend to my friends.

John B. came over to my residence recently to install a new gas water heater as mine had started to fail. John B. provided me tons of information on what each component does, and I felt very confident in his ability to install the water heater. It was also great to find out that John B. is a Navy Veteran as we were talking during the installation process, as I am as well. Kudos to the company for hiring veterans! The price was well within the quote when I called and asked. Would definitely recommend!
