Slab leak on 12 Oct 2017  -  Water penetrated Level 5 floor and dripped from roof slab on Level 3

The above water on the floor of Level 5 may have been from someone washing their vehicle

Below are pics of the ceiling in Level 3 (immediately below the above water on Level 5) which evidence water dripping from Level 5 immediately above

The below pic is the ceiling of Level 3 that was taken a few hours later still evidencing the remnants of the water from Level 5
