Beyond solving rusty water and improving water quality, re-piping your home will also improve your homes distribution of water. Low water pressure is also an indicator that your old galvanized pipes must be replaced. This is because corrosion often builds up in an uneven manner. This results in a minimized inside diameter of the pipe which can impact water pressure for various plumbing fixtures in your home. Re-piping your plumbing system can be done using either copper pipes or PEX Tubing. Both types of pipe are acceptable by Illinois Plumbing Code. The type of material used is determined by the clients preference and budget. Where as, copper piping may cost 30%-50% more depending on current material prices and additional work which may be required for installing rigid copper pipe, which is less easy to work with, then flexible PEX Tubing.
