Sorry to hear this, unexpected change of plans are no fun,
if you can gently put a hole in the area so the water can come out in one spot, with other items as protected as you can, tarp, trash bag under to catch the extra drips. May help reduce the extra damage, and help prevent it from spreading to other areas, giving the water a way out.
Can you guess how I know this?
Hang in there !! (((Huggs)))
