Often times consumers may decide to try to hide from their plumbing problems and decide to "repair" the leaking pipes. In most situations where there are slab leaks, soft copper leaking or thin wall pipes with pin hole leaks, it is time for repiping
If does not make sense to use leak detection unless you only want to do a spot repair. Be careful because some plumbers may try to sell you on the leak detection service and the repair, spot repairs of can be costly because of repeated flooding and water damage. Most home owner's insurance companies will help pay for at least the first or initial water damage incident. But your insurance may be canceled.
Most homeowners insurance policies have deductibles of $500 or more. Having water damage and going through the disruption and discomfort that comes with water damage, flooding, possible mold, destruction of personal property and in many cases having to move out during the drying and restoration process is not worth repeating.
Prevention before disaster is best, if you have a slab leak just re-pipe.
