"Mohammed was smart and diligent. He contacted us quickly, and came to our house on a Sunday within an hour after our telephone chat. Our leaking water heater was replaced by the next morning, and he did this at a fair price. I m recommending him to all of my friends and neighbors."

"Ed was prompt and fair. He came and installed the water heater the same day I called him. He stayed out that night until almost 11 and replaced our water heater. When the city came came and noticed something else needed to be completed in order to pass, he came out at no cost and made sure the job was done. I would highly recommend Ed and use him in the future."

Water Heaters FAQs, answered by experts

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.

Yes, most municipalities have codes that require water heaters to have pans. A pan is necessary when a water heater or hot water storage tank is installed in an area where water leakage could cause damage, such as an attic, second floor, or finished basement. Tankless water heaters are not required to have a pan since there is no storage tank.

Depending on the brand of water heater, you may need to install an expansion tank in order to meet the conditions for warranty coverage. It’s important for consumers to read the fine print of the warranty to see if an expansion tank is necessary. Even if an expansion tank isn’t required for the warranty, it’s usually mandated by building codes—although not for tankless water heaters.

There are many issues that can cause cold showers, but the most likely is a problem with your water heater, especially if other fixtures also don’t get hot water. If it’s just your shower not getting hot water, you likely have a broken or damaged shower cartridge. You can replace this yourself or hire a plumber to do the work for you if you’re not comfortable working with plumbing.

A larger heater requires a larger breaker—unless there’s one already installed. The longer answer to this question is more nuanced. Do you place demands on the heater at the same time as running other heavy-duty appliances like ovens and washing machines? Do you live in an older home that may not have considered the higher electrical demands we have now? Breakers need to be sized at 125% of the load. To find that load, you should call a local electrical pro.
