"SG Quality Builders was the last of 5 different pros we took estimates from. SGQB seemed to be the most knowledgeable and had the expertise to do a complete job installing our new tankless water heater. Because of how our existing water heater was plumbed, installing our tankless was more difficult than most. Serge took the time to explain how the installation would be completed and answered all my questions. The installation was completed as planned including the permit and inspections also handled by SGQB. SGQB did many steps to minimize the disruption to our daily routine and did the little things like covering our carpet when they worked inside the house. The water heater works great. We would definitely invite this pro for future projects."

Water Heaters FAQs, answered by experts

A well-maintained hot water recirculating pump can last 5 to 15 years. Pumps that run continuously may have a shorter lifespan than demand-controlled models. Hard water can reduce longevity by causing mineral buildup in the pump and pipes. Regular maintenance, such as cleaning or replacing filters, can extend the pump’s lifespan.

It is very difficult and dangerous to install your own water heater, so we strongly recommend against tackling this as a DIY project. Not only will you need to wire your water heater, but you’ll also need to connect plumbing to the intake and outlet. Sweating copper pipes and connecting wiring properly are skills most DIYers don’t have, and even if you do feel confident you can do it, working with water and electricity always leaves the potential for electrocution. Hiring a local water heater installer is well worth the investment.

It takes between one and three hours to replace a hot water heater element, depending on whether you hire a pro or do the work yourself. For example, a professional plumber with all the necessary tools and experience can often finish the job in one to two hours, whereas DIY will take two to three hours because it'll involve more preparation and troubleshooting.

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.

Yes, hybrid water heaters can be noisy — noisier than traditional water heaters. The sound they produce is often compared to the hum of a dishwasher. Its noise comes from the heat pump’s fan and compressor as they work to pull in and compress the air. While it’s not totally disruptive, especially if the unit is installed in less frequented areas, like a basement or garage, it’s something to keep in mind if you’re sensitive to noise or if the unit will be placed near bedrooms or living spaces.
