"We had several different technicians working on installing a new water heater in a crawl space. There were several different unexpected occurrences that arose, but the guys were great. They were respectful, curious, helpful, understanding, knowledgeable and extremely patient explaining our oppositions. They were responsive and prompt to some unexpected situations. Highly recommend them, I'm giving the technicians ten stars for their professional and respectful work ethics."

"I had a request of changing a rigid water line to the toilet to a flexible water line and Domingo came on time (almost early, even!), assessed what needed to be done, came back with his tools, and was done in not even 15 minutes! No leaks, kind, and professional, would 100% have in my home again for another repair."

"This was probably my best experience on Angie's List. I woke up and noticed there was no hot water in the house. Went to the basement and noticed the hot water heater was leaking. I called up Advanced Professional Plumbing, told them what was going on and gave them the specs of the hot water heater. 20 minutes later a technician showed up (a very nice guy named Joey). He inspected everything and showed us the cause of the issue. He gave us a few options on what to do and we decided to replace the 75 gallon hot water heater. Within an hour, Joey came back with Sam and they replaced the old water heater with a new one. They were both professional and got the old hot water heater without making a mess and replaced with a new one. After the job was done, Joey tested all the bathrooms out to make sure the pressure was good and we paid and they were on their way. They were fast, efficient, explained everything and it was a great price. You really can't beat that. Your hot water heater breaks down on a Saturday you are not expecting hot water for the rest of the weekend but Advanced Professional Plumbing delivered. I appreciated the office following with me to make sure everything went. Just an overall class business."

"Travis and Elvis were very professional on the phone. Travis provided detailed information and answered all of my questions to better help me understand between options when I was choosing a new water heater for my home. Travis provided me with a free estimate and stayed within the price range we agreed to when completing the job. The water heater was installed in a timely manner. I also received a follow up phone call to check how the water heater was working and if I had any questions which I appreciated. I would definitely recommend hiring this company and plan to use them again in the future."

Water Heaters questions, answered by experts

If you want instant hot water and to reduce water waste while improving convenience, a hot water recirculating system is worth it, especially if you find your hot water heater is not hot enough. These systems can save thousands of gallons of water each year so you don't have to wait for hot water at faucets and showers. The upfront investment can be high, especially for systems requiring additional plumbing, but the long-term savings on water bills and added comfort make them a worthwhile upgrade.

Yes, this would be an appropriate choice. In order to comply with the National Electric Code’s rules, you'll need to install a circuit breaker that's 125% larger than the intended load. In this case, you'll multiply 30 amps by 1.25 to find the necessary breaker size. Plugging that equation in for your 30-amp water heater will leave you with a 37.6-amp breaker. If your current water heater keeps tripping the breaker, it might be time to talk to a plumber or electrician about upgrading your water heater's setup.

A tankless water heater with a flow rate of 10 GPM should replace a conventional 50-gallon water heater. To avoid a surprise cold shower or two and to keep your energy costs in check, it's important to replace a conventional tanked water heater with the equivalent tankless water heater. Your household size and the number of hot-water-using devices you use at once can help you determine the best-size tankless water heater.

Yes, you can replace a current tank water heater with a tankless model or vice versa. If you’re maintaining the same fuel source—gas or electricity—the switchover should be smooth. A conventional tank requires open floor space, while a tankless model can be wall-mounted. If you’re switching to a tank water heater, you might need to clear space for it. Gas-powered tankless water heaters need a large volume of gas when they start running to heat the water instantly. You might need to increase the size of the gas line when going from a tank to a tankless model.

Installing a water heater without a permit can result in high fines—as much as hundreds of dollars per day, in some areas. It can also void your homeowners' insurance and cause problems when selling your home because it violates local building codes and safety regulations.
