A Definitive Guide to Water Loss

A Definitive Guide to Water Loss

The category of water loss pertains to the degree of contamination existing in the water. This is identified from the water source. It’s likewise essential to know how it affects different materials. To put it simply, categories point to how filthy the water is.

On the other hand, water loss classes describe the rate of evaporation based upon the types of wet materials affected. It also depends on the amount of water, from little moisture to great water content soaked by the affected materials.

The Three Categories of Water Loss

Category 1: Clean Water

These fluids are from hygienic sources; they do not pose any significant threats to humans or animals when ingested or inhaled and are considered “clean water.” Nevertheless, they can quickly deteriorate to category 2 liquids.

Examples of Category 1 Water Loss:

  • Damaged water supply lines
  • A water tank or tub overflows without any contaminants
  • Rainwater or melting snow

Category 2: Gray Water

This water contains contaminants that can cause disease or health problems when ingested or exposed to. Referred to as “gray water,” it has a substantial amount of chemical or biological pollutants. It might have an organic or inorganic matter that can trigger health issues.

Examples of Category 2 Water Loss:

  • Overflows from washing machines or dishwashing machines
  • Overflows from toilet bowls (urine only)
  • Broken fish tank
  • Punctured water beds

Category 3: Black Water

The worst classification of water damages and is grossly unsanitary. It might create severe health problems or casualties if ingested. This type of water damage is best left to the care of professional disaster cleanup companies.

Examples of Category 3 Water Loss:

  • Commode backflow stemming from the toilet trap
  • Sewer backflow
  • Flooding from seawater
  • Floods from catastrophic origins include tropical storms, hurricanes, and other related weather disturbances

The Four Classes of Water Loss

Class 1: Slow Rate of Evaporation

A class 1 water loss might affect only a part of a room or an area, or it may consist of more extensive areas that have soaked up very little moisture. Materials impacted have low-permeance or low-porosity such as particleboard, structural wood, vinyl ceramic tile, plywood, or concrete.

Class 2: Fast Rate of Evaporation

A class 2 water loss affects the entire room and materials such as a rug or cushion. Water seepage has gone less than 24 inches up the walls. Moisture stays in structural materials like particleboard, plywood, structural wood, and concrete.

Class 3: Fastest Rate of Evaporation

Water may have originated from overhead. The ceilings, walls, rugs, cushions, insulation, bricks, concrete, and subfloor are saturated with the greatest amount of water.

Class 4: Specialty Drying Situations

Specialty drying includes materials with low permeance or low porosity, such as hardwood, plaster, lightweight concrete, stone, and crawl spaces. There are deep pockets of water saturation that require very low humidity; this class typically needs longer drying times and might require the solution of credible remediation companies like PuroClean of St. Augustine.


If you have experienced water damage or any water-related calamity, it is vital to identify what water categories and classes you will deal with. This information will help the restoration company determine the mitigation strategy and what type of restoration will follow after the cleaning and drying out phases.

Different water categories and classes have particular needs; they are dealt with differently, requiring various devices and approaches to lessen the effect of the water damages. It will be more cost-efficient if the mitigation and restoration job is performed promptly.
