Thanks for your help, there's no leak, it is just the backsplash, have

Time may be a great healer, but it's a lousy beautician.

Hiding the space may work for a while, but aren't you the least bit
curious as to why the backsplash is pulling away for the wall?

Don't you want to fix (or at least stop) the root cause of the problem
instead of just hiding the gap?
