If you have experienced pin-hole leaks from your freshwater supply lines
If you see brown tinted water coming out of your sink and tub faucets
If the water is coming out of your sink and tub faucets at a lower pressure than usual
If you see rust spots or notice watermarks on your ceiling
These are all signs that your homes piping system has rusted all the way through or there is a faulty connection of pipe in your home.
The last thing that any homeowner wants is to install new tubs, counters, cabinets and sinks to have them damaged by rust in the water or torn up later after a major leak. The wisest choice to make before you remodel the kitchen or bathrooms in your home is to assess your homes piping system for a repipe of the existing systems.
