"I would highly recommend Central Plumbing, Travis Brown. He kept me informed about his time of arrival,. He and his apprentice performed their work in a professional manner and even helped me load my old water heater into my truck bed so that I could return it to Home Depot for warranty exchange. I would definitely hire him in the future."

"Javet is a really nice guy and his pluming service is a great value. He is responsive, punctual and professional. We called him for a water heater installation after receiving a ridiculous quote someone else. He provided professional advice for the size and type of water heater to us. On the scheduled the work day, he arrived on time, installed the water heater, replaced a sink, a faucet and a garbage disposal. The quality of his work is great! We would recommend him to anyone!"

"Tyler installed a complete septic system for our new home construction project. This included a 2000 gallon concrete tank with a distribution box and 165â of leach field. The installation was completed ahead of schedule and the site was finish graded very nicely upon completion. The system design engineer and the city building inspector both signed off with positive comments on the quality of work. We used Tyler to trench and install our water connection as well. We intend to use his services in the future also. We highly recommend him."

Water Heaters FAQs, answered by experts

Unless you have previous plumbing experience or extensive experience with water heaters, you should avoid replacing your electric water heater yourself. This process involves disconnecting wiring and parts from the old water heater and reinstalling them onto the new one, among other difficult tasks. This job is best left to the pros to make sure that everything is connected correctly to avoid serious leaks or malfunctions.

Water expands when heated and also when freezing. When water is heated, it expands by around 4%. For a full water heater, this is one of the main reasons malfunctions occur—the hot water has nowhere else to go but out. Due to the constant expansion and reduction in volume, it’s recommended (required in most places) that an expansion tank be installed.

If your gas water heater is over 20 years old, it should be replaced. Gas water heaters can last up to 12 years and while they can exceed this expectancy if well-maintained, a heater that's 20 years old would require replacement. The heater is unlikely to run as efficiently as a new model and could be more expensive to do so.

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.

Due to the high temperature, using stainless steel vent pipes for your tankless water heater’s exhaust vent is best. Also, it is safe to use a flexible vent duct as the exhaust fan. If installing the exhaust fan yourself, make sure you are using heat-resistant silicon to connect the exhaust vent and the duct on your water heater.
