The short answer

Initial Response Steps

When water hits a server, the first move is to cut power to the affected racks. This prevents electrical shorts and further damage. The pros then isolate the area to stop water from spreading to other equipment. They might also place plastic sheeting or absorbent mats around the affected zone to contain any remaining moisture.

After power-down, the pros document the scene with photos and notes. They identify the water source, whether it is a leak, flood, or sprinkler discharge. This record helps your insurance company understand what happened and what was affected. It also guides the drying and cleaning process, since the type of water matters.

Drying and Cleaning Methods

Drying servers requires controlled methods. The pros use dehumidifiers, air movers, and sometimes vacuum chambers to remove moisture from internal components. They avoid heat that could warp parts or damage circuitry. Instead, they rely on low-temperature drying and good airflow to draw out moisture slowly.

Cleaning involves removing corrosion and residue from circuit boards. Specialized solvents and brushes help lift contaminants. The pros may disassemble servers to clean each part individually, depending on the water type and exposure time. For example, saltwater leaves behind conductive salts that must be rinsed away carefully.

  • Power down immediately to prevent shorts
  • Document water source and affected equipment
  • Use dehumidifiers and air movers for drying
  • Clean circuit boards with specialized solvents
  • Replace corroded connectors and drives
  • Test components before reinstallation

Assessing Salvageability

Not every server survives water damage. The pros evaluate each unit based on water type, exposure duration, and component condition. Clean water causes less damage than dirty or salty water, which can corrode quickly. They also check for signs of electrical arcing, which can make a unit unsafe to reuse.

Data recovery is often possible even if hardware fails. The pros may remove hard drives and send them to a data recovery service. That way, your information has a better chance of being retrieved, even if the server itself is beyond repair. Recovery success depends on how long the drives were wet and whether they were powered on.

Preventing Future Incidents

After the immediate cleanup, the pros recommend changes to reduce future risk. This includes installing water leak detectors, rerouting pipes away from server areas, and ensuring proper drainage. Regular inspections of cooling systems also help catch problems early. You can also place servers on raised platforms to keep them off the floor.

If you live in Columbus, keep your shutoff valve location written down so you can act fast in an emergency. A quick shutoff can limit water spread and reduce the damage to your equipment. You might also consider adding a secondary shutoff valve on the water line feeding your cooling system.

When to Contact the Pros

If servers get wet, act quickly. The longer moisture sits, the more corrosion and damage occur. Contact local water damage pros who have experience with electronic equipment and can begin the drying process. They can also help you prioritize which units to address first, based on the value of the data and hardware.

The pros can handle the cleanup and drying, but they do not repair circuit boards. For hardware repair, you may need a separate electronics specialist. Always check your insurance policy to understand what is covered and what documentation you need. Keep a log of all actions taken after the incident, as this can support your claim.

  • Act fast to limit corrosion
  • Call local water damage pros for cleanup
  • Consult an electronics specialist for repairs
  • Check your insurance policy for coverage details

Frequently asked questions

Can a water-damaged server be repaired?

Sometimes, if the water is clean and the server is dried quickly. The pros assess each component for corrosion and damage. Hard drives may be recoverable even if other parts fail. A specialist can often salvage data, but full hardware repair depends on the extent of damage.

What should I do immediately after a server gets wet?

Power down the server right away to prevent electrical shorts. Unplug it if safe. Document the water source and take photos. Then call the pros to start drying and cleaning. Do not attempt to turn it on until a professional inspects it.

Does insurance cover water damage to servers?

Policies vary, and your insurer decides what is covered. Many business policies include water damage from leaks or floods, but exclusions exist. Review your policy and file a claim promptly. Keep records of the incident and any repairs for your claim.
