"Top notch service!!! Our water heater went out and we needed a new one ASAP! These type of problems always happen at the worst and most inconvenient of times. We called around and no one could make it out for at least a day? some were two days! We called Water Heater SOS and explained our need for a new water heater ASAP, they explained they had a lot of calls that day but assured us they would send someone out by end of the day.. within the hour they called us back and said they were sending one of their guys right now!!! They were extremely professional, polite and worked fast and efficiently to get us a new water heater up and running by the end of the day!!! We HIGHLY recommend Water Heater SOS"

"I met Josh and his company and was on my 1st home project installing a recessed refrigerator bib. Work was done very professional and quickly, made a big difference in working with small opening. Rehired Josh a couple weeks later to install 2 toilets,bathroom sink faucet, and do some repair on my kitchen faucet, again great work. Very good prices!"

"We had a need for quick service to replace a 26 year old water heater. Isaac stepped up and installed a new, high-rated water heater the same day at a competitive price (based on what I had paid recently to install the same water heater at a different location). His service and attention to detail was much appreciated."

"Rafael came and was able to get our water heater pilot working quickly in a very professional manner. He the took extra time to go over its operation. There was no push to replace the heater which is eight years old, if I have more serious plumbing issues in the future, I will definitely call Diamond first."

"We had a great experience with GG’s Plumbing at our cabin in Lake Arrowhead. We originally hired them to install a whole-house water shut-off system, and the job was done quickly and professionally. While they were there, the team noticed that our pipes weren’t properly insulated — something that can obviously become a real issue in the mountains during winter. What I appreciated most was their approach: they didn’t pressure us at all. They simply explained the risk, gave us the option to fix it now or later, and let us decide. That kind of honesty goes a long way. We chose to go ahead and have the insulation done, and I’m glad we did. Their team was easy to work with, the communication (mostly through text) was fast and clear, and everything was handled smoothly. Reliable, knowledgeable, and straightforward — I would absolutely recommend GG’s Plumbing."

Water Heaters FAQs, answered by experts

A larger heater requires a larger breaker—unless there’s one already installed. The longer answer to this question is more nuanced. Do you place demands on the heater at the same time as running other heavy-duty appliances like ovens and washing machines? Do you live in an older home that may not have considered the higher electrical demands we have now? Breakers need to be sized at 125% of the load. To find that load, you should call a local electrical pro.

The size needed for your expansion tank is determined by the size of your home's water heater. Expansion tanks are available in 2-gallon and 4.5-gallon sizes. A 2-gallon tank will be appropriate for water heaters up to 50 gallons. An adequately sized tank should have a volume that equals 2% to 5% of the water volume within the system. A plumber can evaluate your home's water pressure, water heater size, and other factors to provide suggestions for picking out the best expansion tank.

The average lifespan of a water heater is eight to 12 years. If your water heater is approaching its first decade of life and is giving you problems, talk to a plumber about your replacement options.

Keep in mind that certain parts of a water heater, such as the anode rod, may need replacement long before the heater itself. An anode rod often has a lifespan of three to five years.

A water heater is one of the heaviest hitters in your home, and it needs as much power as possible to help it run efficiently and effectively.

Your water heater should be on its own dedicated circuit breaker, with no other power sources running to it. This is required to meet the National Electric Code–and to ensure it runs as efficiently as possible.

Newer models are packed with newer technologies that decrease energy consumption and increase output, giving you more bang for your buck in more bills than one. 

If you’re trying to decide whether you want to repair or replace your new heater, consider factors like your utility bills, repair costs, and even your carbon footprint to help you decide whether it makes sense to buy a new one instead.
