It’s technically possible in some areas to install your own fire suppression system, but it’s usually not a good idea. Your system must conform to the fire code in your area and will need to pass a rigorous inspection before being activated and deemed safe. Installing a fire suppression system is a complicated job, and making mistakes as a DIYer is likely. Those mistakes can cause you to fail your inspection, which means you’ll have to spend more time fixing the issues or money to have a certified plumber do the work for you. It’s best to hire a professional.

A home fire sprinkler system reduces heat, flames, and smoke within seconds. Fire sprinkler systems hide in walls with sprinkler heads running along the piping throughout your home.

When the air surrounding a sprinkler reaches a specific temperature, the heads closest to the fire activate and release anywhere from 10 to 25 gallons of water per minute.

Your pilot light needs to be on whenever you’re using your furnace to heat your home. However, you might decide to turn it off during the summer months, when you don’t need heating. Doing this can save you a little bit of money on utility costs—just make sure you’re fine with relighting your pilot light (or hiring a professional to do it) when fall comes around and you’re ready to get cozy.

A grease fire starts if hot cooking oil comes into contact with a heat source, such as an electric heating element or the flame on a gas range. Once the grease is ignited, it can be very difficult to put out.
