Orange County supply potable water from underground reservoir called the Floridan Aquifer. It's primarily fed by rain water and filtered by sand and rock in a natural filtering process. According to the county it needs little or no treatment other the disinfection and aeration to remove hydrogen sulfide.The disinfection is achieved by adding chlorine to the water which is very harsh on your homes water distribution system severely cutting the service life of your system and fixtures.
In the early 80's Polybutylene pipe was used in many homes up until 1995 when it was removed from the market. It is no longer allowed by plumbing code and was found that chlorine in the water cause the pipe to crack and fail causing major water damage.
Most homes in the Orlando area have copper pipes that run under the concrete slab, it's a good idea to shutoff every fixture in the home and take a look at the meter and make sure there's no water flowing. Most meter in Orlando Florida have a leak indicator usually a small triangle that will spin when water if flowing. If you have a leak the movement on the indicator will depend on the size of the leak, so pay close attention to it because you might think it's not moving at all. You can put a piece of painter tape close to one of the points of the triangle and mark it with a pen this should help you decide if its moving.
At this point if you find the leak indicator spinning and your sure all the water in the home is off there's a good chance your home is one of many in Orlando, FL area that have a slab leak. A slab leak could be repair but not recommended due to the high chance of another leak popping up. The best solution would be a re-pipe.
Copper used under slab home construction is type M and comes in a roll in the field we call it soft copper, it doesn't hold up well in the Florida ground. We see a lot of failure on the hot side of the water distribution system.
CPVC can become brittle over time and if it's exposed to an extreme environment like what you would find in a florida attic in the summertime, the temperature can reach 180°F making it less flexible increasing the chances of a major leak and causing water damage.
