Measuring Water Loss

How much water is my pool losing?

GOAL: Find out rate of water loss in inches/24hrs. (ROL “/24hr)

  • Use a piece tape to mark the water level on the faceplate of the skim box. The bottom edge of the tape should rest right on the water level.
  • Wait 24hrs, re-mark water level and use a measuring device, like a ruler, to calculate the rate of loss (inches/24hr).
  • Label your markings with date and time.
  • If this result is inconclusive, leave original markings and repeat this process as needed. Please leave all labeled markings on the pool for the diver to observe.
