Do You Need a Professional to Replace a Water Heater?

Do You Need a Professional to Replace a Water Heater?

Yes. DIY projects are popular now, but trying to replace your water heater yourself is actually dangerous. It may seem like a good way to save money, but it’s just not worth the risk. Please, hire a professional. It doesn’t even have to be us (although we’re qualified), but please, don’t try to do this yourself.

Explosion or Fire

Water heaters often use natural gas to heat water. Natural gas is combustible, so a mistake when replacing a water heater could result in a fire or explosion which could hurt or kill people.

Carbon Monoxide

Small mistakes when replacing a water heater can cause carbon monoxide (a colorless, odorless, poisonous gas) to build up in your home which can be fatal. You can’t see or smell carbon monoxide which makes it even more dangerous.

Call a professional to replace your water heater, and buy a battery-operated or battery back-up carbon monoxide detector. They’re not expensive and might save your life.

Read some tips on avoiding carbon monoxide poisoning, and watch out for symptoms such as “headache, dizziness, weakness, upset stomach, vomiting, chest pain, and confusion” as given by the CDC.


Fixing your water heater yourself will void your warranty. Additionally, if you installed the water heater yourself and later tried to sell your home, you would have to get the heater inspected or even reinstalled which would cost a lot of money.

Finally, according to one source, “Your plumber will know all of the local building and fire codes, and will be able to easily obtain all of the proper plumbing permits guaranteeing the job is done correctly, safely, and legally.”


As a non-professional, it will likely take you a lot longer to replace the heater. A professional with years of experience will be able to do it much more quickly.


Installing a water heater yourself just isn’t safe. One plumbing company wrote: “Because of the exceptionally hot water, carbon monoxide, natural gas, electrical wiring, and pressure-controlled tank, one tiny mistake could mean catastrophic damage and/or injury if the unit is not installed properly. Your plumber knows exactly what to do and how to properly handle each of these hazards to minimize any risk of damage or injury.”

While DIY projects are popular, this one isn’t worth the risk. Please call a professional.
