What to Do When a Water Main Breaks in Your Home

Run to the phone and call an emergency plumber. Once the water is off, the panic is over and a licensed professional plumber will help you repair the main water coming into your house. A water main break looks and sounds like a catastrophe, water spreading across the floor in seconds, but the real emergency ends the moment the water stops. Get it shut off, call a pro, and the rest is a repair instead of a crisis. If a broken water main has you standing in water right now anywhere in the Orlando area, call Herrell Plumbing at (407) 273-6260 or reach out to our team and we will get someone headed your way.

What Should You Do the Moment a Water Main Breaks?

Shut the water off, right away. Find your main shutoff valve, which is usually where the water line enters the house, in the garage, a utility closet, or an outdoor box near the foundation. Give it a firm turn clockwise and the flow stops. That one move ends the flooding.

Here is the snag we run into constantly in older Orlando homes. Sometimes the house valve is seized, painted over, buried, or nobody ever knew where it was. When that happens, the water has to be shut off at the meter out by the street, and that usually takes a meter key, a cheap little tool worth keeping in a drawer in the garage. Once the water is off, you are out of the emergency and into a repair, so take a breath. Do not try to patch anything with the water still running, and stay clear of standing water near outlets or the electrical panel.

Can You Repair a Broken Water Main Yourself?

Shutting the water off, absolutely. Repairing the main line itself, no, that is a job for a licensed professional. The main is the single pipe feeding your whole house, and it runs under constant pressure, so a repair that is a little bit wrong either fails again or floods the place a second time a week later.

There is code to meet and the meter to work around, and across most of Orange and Seminole County the line from the meter to the house is the homeowner's responsibility, which means the repair has to pass local plumbing code. We have been fixing these since 1970, and how we fix it depends entirely on what the line is made of. Copper, PVC, and galvanized all fail in their own way and get handled differently. A clean break in a PVC line is often a quick repair. Old galvanized or corroded copper is a different animal, and that is the question almost every homeowner asks next.

How Much Does It Cost to Fix a Broken Water Main?

Repairs start at about $275 and go up from there, depending on the material, how deep the line sits, and how hard it is to reach. That is honest. It is a real starting range, not a teaser number. The bigger money question is repair versus replacement.

If your water line is anything other than PVC, we usually recommend replacing it instead of patching the one spot. Old galvanized and copper mains that fail once tend to fail again a few feet down the pipe, so a patch just buys you time until the next leak. That is where a full water line replacement comes in. It costs more up front, and it ends the cycle of emergency calls. The part people underestimate is the cost of waiting. A main that keeps leaking runs the water bill up fast, and water working its way under a slab or into a wall can do thousands in damage long before you ever see a stain. A few hundred dollars now almost always beats what the delay costs.

How Do You Avoid Hitting a Buried Pipe When You Dig?

Call Sunshine 811 before you put a shovel in the ground. It is free, and in Florida it is the law. You call 811 or request it online a couple of business days ahead, and the utilities come mark where the gas, electric, water, and communication lines run, so you are not digging blind.

This one matters more than people expect. We see homeowners start a paver walkway or a landscaping bed, hit a pipe they assumed was an old irrigation or sprinkler line left by the previous owner, and find out it was the main water line into the house. Take a sawzall to that and water is everywhere in seconds. Buried utilities are a much bigger risk than a leaky pipe, because cutting into a gas or electrical line can seriously hurt someone. So if you are not certain what a pipe is, do not cut it. Have a licensed plumber identify and cut the line, and get your main shutoff located before the project starts, not in the middle of the flood. You can schedule the 811 locate through Sunshine 811 yourself.

What Should You Do After You Accidentally Cut a Water Line?

Shut the water off, call a licensed plumber, and only then start the cleanup. In that order. Once the water is stopped, take a few minutes to document the damage with photos and video before you mop anything up, especially if the water reached flooring, drywall, or anything stored nearby.

How far you take it from there depends on how much damage there is. A small cut with little water may just need the line repaired and a few towels. Water that soaked a finished room is a call to your homeowners insurance, and the photos you took in those first ten minutes are what back up the claim. We handle the plumbing side, get your water back on, and give you a straight answer on repair versus replacement, not a sales pitch. If you have hit a line or found a broken water main at your home, call Herrell Plumbing at (407) 273-6260 or contact our office and we will get it shut down and fixed.
