Under-slab leaks
Leaks beneath a slab can introduce water into soil near the foundation and may be difficult to see directly.
Testing can clarify conditions
When symptoms or repair plans suggest a plumbing concern, leak testing may help determine whether plumbing work should be coordinated with structural work.
After foundation work
Some projects involve plumbing checks after structural adjustment because movement can affect buried or connected piping.
Do not assume causation
A leak and a foundation problem can occur together without one necessarily being the sole cause of the other.
