"My current 10-year 7-month-old water heater from Bradford White developed some issues with the control panel. The cost of repairing the control panel versus a new water heater was a no-brainer. We opted for a new water heater and the service we received from Sam R, a technician for the Water Heater Company was outstanding. He is so meticulous in getting everything done correctly. He kept the work area clean and kept me well-informed on what needed to be done as he worked. I would highly recommend this company. I included the images of the old unit in the process of being removed and the finished project."

"Ok so this man Giovanni is a rare find. Read his reviews they are real reviews. I had a problem no hot water and we had a new tankless hot water heater put in 9 months ago. So did some research and as soon as I read Giovanniâ s reviews I stopped searching. The review of the son being concerned that Giovanni was going to take advantage of his older mother is the main review that sold me. So this is what happen, I called and spoke to Giovanni around noon. He was going to squeeze me in around 2:30. He had other appointments. So around 1:30 a friend can to my house and I told her about the hot water so she said let me see. She started going into settings and with a few clicks it started working. I then sent Giovanni a text telling him what took place. He called me I told him what my friend did and walked him through the steps. He said all was good except to take off always running and put on intelligent, which I did. So now the next day I get home from work turned on hot water and just warm after 5/6 minutes of running. So thinking there was still the problem I text Giovanni and ask if he could come and look at it either today or tomorrow told him about the warm water. He then text me back saying that the intelligent needs to relearn when we use water. He also told me to turn on hot water in few different places in the home. And yes he was right the water got hot very hot. It just needs to relearn when we use hot water. I have paid this man nothing, he talk me out of having him come to my house because he doesnâ t feel there is a need for him. He told me it could take a week to learn, and if I did have problems to call him back. WHAT A GREAT GUY. I kinda hope it does break just to meet this incredible man. THANK YOU GIOVANNI. Need to update this review because I did have him come to my house for a feew liitle things. He quoted my $1,595.00 for 3 didderent fixed. The reason why I am writing this is because after he started the work he realize that one of the issue I had didn't need as much work as he first thought. He removed $400.00 from my bill. He could have said nothing because the issue was in the craw space and I would have nevered known. That is a really great guy and an incredible plumber without a doubt. Would refer him to anyone and everyone!"

"We’ve hired Fix it quick for a few things and never got charged for an estimate and they never tried to upsell me. We also hired them to replace our water heater, which they realized was likely due to a faulty water pressure regulator. They fixed it quickly and were very reasonable with the pricing. They were professional and I will continue to hire them for all my plumbing needs."

FAQs for water heater repair or service projects in Simi Valley, CA

Warning signs include fluctuating water temperatures, a pilot light that repeatedly goes out, unusual noises from the tank, or complete heating failure. You might also detect a rotten egg smell, indicating a potential gas leak, or notice water that never reaches the proper temperature. If your water heater is over eight years old and displaying these symptoms, the gas valve is a likely culprit. Professional inspection is recommended, especially if gas odors are present.

Water heater gas valves are not universally interchangeable. Each valve must match your specific water heater's make, model, and specifications. Important compatibility factors include gas type (natural gas vs. propane), BTU rating, connection types, and physical dimensions. Using an incorrect valve can result in poor performance, premature failure, or dangerous gas leaks. Always consult your water heater's documentation or a professional plumber to identify the appropriate replacement valve for your unit.
