Repairing the Slab Leak

When my foundation repair consultant, Richard Nash, suggested I have a plumber out to check for a slab leak, he made one criteria clear.

“Have them wait at least two hours to see if the water level drops.”

Here is what he meant. A lot of the slab leaks in houses built in the 1970s as mine was occur in the out-going or sewer lines. And that is because the cast iron pipes used under the concrete slab foundations are starting to fail.
