One leak. Twenty floors of damage.
The higher the leak, the more rooms compound the loss before anyone responds. The simulator uses operating-portfolio data from the State of Water Risk ’26 report to show how long a leak runs before anyone finds it, how much water it releases and how many floors sit below it. Then it shows what changes when Eddy is on the chain.
Cascade damage simulator
Pick a floor, leak source and time of day to see how long the water runs, how much of it there is and how many floors sit below it.
Leak source and est. damage if undetected
Unmonitored, water from floor 8 keeps working down through the 7 floors below until someone finds it.
How these figures are made
Time to find a leak without monitoring: overnight, until the 8 AM walk-through, the low end of the report's 6 to 8 hours for a 2 AM leak. Daytime and evening times are estimates of when someone notices.
Water released: 5 to 8 gallons a minute, what a 3/16 to 1/4 inch hole in a supply line passes at 60 psi. A burst washer hose runs faster, about 650 gallons an hour (State Farm), and a condensate drip slower.
Damage by source: State of Water Risk '26, Eddy's base estimate of what an undetected leak from each source would cost on average in a multi-family building, before the report adds the extra cost of leaks after hours or on upper floors. Monitoring: the Aon Real Estate Practice whitepaper on the Eddy system found it would have positively affected 58% of the water loss claims it studied and cut total water damage losses by 23%.
Next steps
Turn the cascade math into a plan.
The calculator runs the full risk profile against the report's operating-portfolio data, the WDPP builder generates a project-ready document and the State of Water Risk '26 report carries the numbers into the renewal conversation.
