"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."

"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."

"Very, very happy with the services Toptec provided. I used them for installing a new hot water heater, installing a new furnace, and some minor electrical work. First of all, very professional. Brian came out, talked to me about what I needed and wanted, and gave me some suggestions. He provided a quote that gave me a few options, with absolutely no pressure to upgrade or add on services. The quote was more than competitive with other contractors I talked to. After I agreed to the contract, Toptec had Brian and John out to perform the work the following day. Both were very professional, clean, and the work looks superior. Immediately following my good experience, I had a minor electrical problem. Called Toptec and they had Gary out to my house in 45 minutes. Again, top of the line professional who figured out a weird wiring situation. When I go to upgrade my electrical I will definitely use Toptec and request Gary. Highly recommend this company."

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.

A thermocouple is a pretty simple device. It simply tells the control valve if heat is present. Most water heaters can use a universal thermocouple, provided it's the correct length. Getting one that's long enough for your appliance is crucial for success. However, some water heater models require model-specific thermocouples, which is why it's essential to take your existing one to the store to find the right match.

When replacing an old unit, you might want to switch from a gas water heater to an electric water heater or vice versa. To do this, you will likely need to add infrastructure to the area. For example, you likely don’t have a gas line that served your old electric water heater. You’d have to call a plumber to put in a new gas line. If you’re replacing a gas unit with an electric one, the plumber will need to safely cap the old gas line. You will then need an electrician to add wiring for the new electric unit.

Your water heater's age can affect your homeowners' insurance policy. Many policies will ask how old the heater is when you first apply for a policy—and they may make you replace a model that's over 10 years old. 

Even if your policy permits you to have an older heater, it may significantly reduce the amount of protection available. If an older water heater suddenly leaks and causes damage to parts of your home, your policy may not cover it.

Unusual noises, lack of hot water supply, efficiency loss, and visible leaks are signs of necessary replacement beyond mere repair.
