Information I found was that the municipal water supply was sanitized with Chlorine for many years but they changed to Chlorimine around 2000 or so. The pinholes were atrtributed to the Chlorimine effect on copper. Once it looked to be a problem many municipalities swirtched back to Chlorine and problems dropped off although in many homes the damage was already done.
Pinholes are not only in the floor but do happen in the walls. My neighbors have experience that first hand.
Best to replumb for insurance and safety proactively than reactively. The costs after the fact are much more than the cost to do it right.
Lots of information here but I do have a few things to add.
Pinhole leaks often occur copper plumbing within the walls as well as within concrete. The exact cause of the leaks is suspected but unknown. Since the leaks are common regardless of the location of the copper pipes many believe that the leaks are caused by excessive treatment of water at the water treatment facilities. The thought is that it is actually the water drawing minerals (or other impurities) out of the copper which result in the leaks.
That said, pinhole leaks in copper pipes are not exclusive to our area. It is well known that copper plumbing is susceptible to having pinhole leaks in many parts of the US and also worldwide.
Yes, "re-plumbed" does refer to having the copper plumbing that was leaking replaced. Some of the "re-plumb" jobs are complete and some are part. As you can imagine, there are some pipes that are easier to get to than others. Typically, when a property is re-plumbed CPVC pipe is used. It is commonly referred to as PVC pipe. This is a flexible "plastic" type pipe material that can be installed with minimal holes being cut.
There are also companies that offer a service to "coat" the inside of copper plumbing with a liquid material that seals the current holes and keeps the water from interacting with the interior surface of the copper plumbing.
Probably more information here than you need but I hope this helps!

Not all homes are affected by pinhole leaks.
Each area has their inherent issues. In Pinellas and Hillsborough sink holes are of concern. Some new home subdivisions were built on pasture lands and the trees are immature. Thus, you'll have to wait til they grow.
It is part of living in Florida.

It is very rare that a repipe still uses PVC. The most commonly used piping for new construction and repipe plumbing is called PEX, made from high density polyethylene. It is run through the ceilings and walls making it more easily accessible in the event of a leak and more easily identifiable as hot and cold water lines use different color pipes, red for hot and blue for cold.
PEX is also easily adaptable to what is called a â€œmanifoldâ€ system where each pipe enters a box, usually located in the garage, and is then distributed to different locations in the home. A huge benefit of this system is that each and every location has its own shut off valve at the manifold and a leak can quickly be isolated without having to crawl under a sink or squeeze behind a toilet.
If a leak is found in a foundation and requires a â€œrepipeâ€ or â€œre-plumbâ€ it is not the end of the world. While it is not a cheap repair, it is usually not terribly expensive (although inconvenient) and will result in a far better plumbing installation.
My understanding of "re-plumbed" (also known as re-piped) is when pipes that were once run through the foundation of a home have been rerouted overhead and down walls. Pipes run through the foundation of a home, especially if they are copper, are more susceptible to leaks. A re-piped home uses PVC.
I hope this is helpful!

Homes in parts of Sarasota with copper plumbing experience corrosion which causes pinhole leaks. Because so much of the original copper plumbing in an older home is in the foundation slab, this causes major repair issues.
