The short answer

Immediate Steps to Stop the Water

Your first move is to find the main water shutoff valve for the sprinkler system and turn it off. This stops the water from continuing to pour out. If you cannot locate the valve or it is stuck, call a plumber or the building's maintenance contact right away.

Once the water is off, turn off the electricity in the affected areas at the breaker panel, if it is safe to do so. Water and electricity are a dangerous mix. Avoid walking through standing water until the power is off. If you feel unsafe at any point, leave the building and call for help.

Removing Water and Drying Out

Start removing water as soon as it is safe. Use a wet vacuum or mops and towels to soak up as much as possible. The longer water sits, the deeper it soaks into flooring, drywall, and wood, causing swelling and warping. Open windows and doors to increase airflow and speed up drying.

Use fans and dehumidifiers to pull moisture from the air and surfaces. In a humid climate with warm summers, drying can take longer. If the water has reached multiple rooms or floors, local water damage pros have industrial equipment that can handle the job more thoroughly.

  • Turn off the water at the main valve first.
  • Switch off electricity in wet areas.
  • Remove standing water with a wet vacuum or towels.
  • Set up fans and dehumidifiers to dry the space.
  • Move furniture and belongings to a dry area if possible.
  • Document the damage with photos for your records.

Assessing Damage to Belongings

Check your personal items for water damage. Books, papers, and photographs may be salvageable if dried slowly. Electronics, such as computers or TVs, should be unplugged and left to dry completely before you attempt to use them. Do not turn them on while they are wet.

Artwork and antiques can be especially vulnerable to water. If you have valuable pieces, a professional who specializes in artwork or antiques restoration may be able to help. For electronics, consult an electronics restoration service. Act quickly, as mold can begin to grow within 24 to 48 hours in humid conditions.

  • Dry books and papers by separating pages and using fans.
  • Unplug all electronics and let them dry fully before use.
  • Remove wet carpet and padding to prevent mold.
  • Check walls and ceilings for water stains and soft spots.
  • Move valuable items to a dry, ventilated area.
  • Take photos of damaged items for your records.

Working with Your Insurance

Contact your insurance company as soon as you can to report the incident. They will guide you on what documentation they need, such as photos and a list of damaged items. Keep records of any receipts for supplies you buy, like fans or dehumidifiers, as they may be relevant to your claim.

Policies vary, and your insurer decides what is covered. Ask your insurance company about coverage for water damage and whether they have preferred vendors for restoration work. You can also hire the pros directly, but check your policy first to understand any requirements.

Preventing Future Incidents

After the immediate crisis is handled, think about prevention. If vandalism is a concern, consider installing a protective cage or cover over the sprinkler head. Make sure the shutoff valve is clearly labeled and accessible, and write down its location so you can find it quickly in an emergency.

Regularly inspect your sprinkler system for signs of tampering or damage. If you live in a multi-unit building, talk to your landlord or building manager about security measures. Keeping the area around sprinklers clear can also reduce the risk of accidental or intentional damage.

Frequently asked questions

How long does it take for mold to grow after water damage?

Mold can start growing within 24 to 48 hours in warm, humid conditions. That is why it is important to dry out the area quickly. Use fans and dehumidifiers, and remove wet materials like carpet or drywall if they cannot be dried completely.

Can I dry out my electronics myself after they get wet?

You can try, but it is risky. Unplug them immediately and let them dry for several days in a dry, well-ventilated area. Do not turn them on until they are completely dry. For valuable or complex electronics, consider a professional electronics restoration service.

What should I do with wet artwork or antiques?

Handle them gently and avoid rubbing or wiping the surface, as that can cause further damage. Place them in a dry, well-ventilated area and let them air dry slowly. For valuable pieces, contact an artwork or antiques restoration professional who has the right tools and experience.
