We’ve talked before about slab leaks, one of the more difficult problems when it comes to residential plumbing, but we’ll go over them again to give you an idea what you (and our plumbers) are dealing with.
A slab leak is any pipe leak set down in granite or other hardscaping on a residential (or commercial) property. In most cases, when plumbers talk about slab leaks, they are specifically talking about leaks in the cold water and hot water pipes down in the foundation of a house, although pipes in slabs can be found elsewhere. Around 80% of slab leaks happen in hot water pipes, which expand with heat to abrade faster against the stones around them.
