"After buying a water heater at Menards and getting it home, I called Plumb-it Inc about 1:30 p.m on a Monday. I think it was Scott who answered (no recorder!) and he said he could have 2 guys out to our house within 45 minutes to install it. The job went so smooth. They did arrive within 45 minutes. The 2 guys were very knowledgeable about installing a heater. They were efficient, quiet, polite and cleaned up afterwards. They also took the old heater and the box the new heater came in. What more could we ask for? They did everything we expected."

"I called Top Tec Oct 4 to check my existing water heater. Steve came out and looked it over and gave me the bad news. My 9 year old water heater was shot. The next day, Steve removed my old water heater and installed a new Rheem water heater. I could not be more pleased with how quickly the work was completed and with Steve’s expertise!"

"We hired Da Vinci to install new water service and sewer connection to municipal water. The initial challenge was obtaining permits from 3 jurisdictions. Mike from Da Vinci took care of all administrative and legal requirements. He refused to let the bureaucracy stall the project. Once permits were in hand, work commenced immediately. Da Vinci OWNS all tools and equipment required to install underground work. No delays for equipment rental! Work proceeded quickly and efficiently. Mike kept us updated on progress and when he expected to be complete. A pleasure to work with. Highly recommended."

Water Heaters FAQs, answered by experts

The right way to vent a gas water heater is to have a pipe directly upward or slopes upward out of the house. Because hot air naturally rises, this type of venting will efficiently ensure that all gas moves out of the house. Your system may rely on fans or blowers as well.

Excessive pressure (above 80 psi) puts too much stress on plumbing pipes, joints, and fixtures. This can lead to leaks and burst pipes. Plus, it shortens the lifespan of appliances, can waste water, and can raise your utility bills. High water pressure might feel like a gift, but it’s actually a silent threat to plumbing.

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.

The amount of time it takes to replace an electric water heater will depend on the skill level of the individual who is replacing it. For example, if you replace it yourself–and you don’t have much experience–you can expect the project to take a full day. 

However, if you have a certified plumber or water heater contractor install your new water heater, it can take as little as 2 to 3 hours.

Most hot water heater manufacturers recommend replacing the anode rod about once every three to five years. Anode rods sacrifice themselves by collecting iron, limestone, and other minerals that would otherwise corrode your hot water heater tank. This abuse wears them out long before your water heater does. Check the rod when you remove it and replace it if more than 50% of the metal has been consumed. Check the rod more frequently if you have hard water or use a water softener.
