The short answer
Heat Effects on Pipes
The extreme heat of a house fire can damage pipes in several ways. Plastic pipes, such as PVC or PEX, can soften, warp, or even melt when exposed to high temperatures. This can cause joints to separate or pipes to collapse, leading to leaks once water flows through them again.
Metal pipes, including copper and steel, are more heat-resistant but not immune. They can expand and contract, potentially causing cracks or weakened joints. The heat can also damage the solder or threads connecting sections, making them prone to failure later. Even if pipes look fine on the outside, internal damage may be present.
Water Damage from Firefighting
Firefighters use large amounts of water to extinguish a fire, and that water can enter your home's plumbing system or flood the structure. If pipes are damaged, water may escape through cracks or melted sections, causing further water damage to walls, floors, and ceilings. The water itself can also be corrosive or contain residues that affect pipe integrity.
After the fire is out, the water that remains in the pipes can freeze if the heat is off, especially in cold weather, leading to burst pipes. Even without freezing, standing water in damaged pipes can cause rust or corrosion over time. It is important to shut off the main water supply to your home as soon as it is safe to do so, to minimize additional water damage.

Immediate Steps for Homeowners
After a fire, your safety comes first. Wait for the fire department to declare the structure safe before entering. Once it is safe, locate your main water shutoff valve and turn it off to stop water from flowing into damaged pipes. This can prevent further water damage and give you time to assess the situation.
Document any visible damage to pipes and take photos for your insurance records. Contact your insurance company to report the fire and ask about coverage for pipe repair and water damage. Policies vary, and your insurer decides what is covered. Do not attempt to repair pipes yourself until a professional has inspected them, as hidden damage can cause sudden leaks.

Can pipes burst during a fire?
Yes, pipes can burst during a fire due to extreme heat causing them to expand and crack. Metal pipes may weaken, while plastic pipes can melt or warp. Additionally, water inside pipes can turn to steam, increasing pressure and leading to rupture. After a fire, inspect pipes for leaks.
How soon should I check my pipes after a fire?
You should check your pipes as soon as the fire department allows you to re-enter the home. Turn off the main water supply immediately to prevent leaks. Then, have a professional inspect the pipes for damage before turning the water back on. Delaying can lead to hidden leaks and water damage.
