A certain way to check to see if you have a slab leak would be to check the dial on the water meter when no one is using water. Mark a line where the dial is now and then notice if it moves.If it does then you have a leak, if it does not then you do not.
If you have a leak there are tools to electronically detect where it is. Call your local Licensed Plumbing Contractor.

There is a 40 gallon fish tank in the same area, however, there is no evidence that the tank is leaking.. could I have a slab leak and if so how would I know.. What should I kook for?[/QUOTE]
