"In March 2020, Clean Team Plumbing repiped our home and installed a tankless water heater. Brad was professional and honest. Our service technicians Artis and Lazurus were great and their workmanship was beyond reproach. All my questions and concerns were answered timely and professionally. The drywall team was top notch. Thank you Clean Team Plumbing for the great job."

"Brian from EZ Flow responded my requests promptly, committed to the schedule and plan. The installation of the water heater was smooth and quick. Wish the gas line was installed closer to the wall as Brian originally planned so as to leave me more space."

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.

No, you’ll need to drain the tank before changing a water heater element, as the water heater element sticks through the side of the tank and uses a gasket to prevent water from pouring out. However, you don’t always need to drain it completely. If you’re only replacing the upper heating element, you can drain the tank until the water line is below the element. If you’re replacing the lower element, you’ll need to drain the whole thing.

The average water heater holds between 40 and 60 gallons, but the exact amount of water that comes out during draining will depend on your unit’s capacity. The amount of time it takes to drain a water heater averages from 10 to 30 minutes.

Typically, only a high-efficiency water heater with an inducer fan can be vented outside the house. Otherwise, your water heater needs to be installed on the inside and vented through the roof. However, certain areas may allow a standard-efficiency water heater to be vented outside. Check your local building codes to be sure.

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.
