Many homes were built with galvanized plumbing which rusts and detoriates over time. You may notice that your appliances are filling up slower than they used to, the pressure in your shower just isn’t what it used to be, and you occasionally notice a brown tinge to your water when you turn on your faucet.
What’s happening is your galvanized pipes are slowly but steadily filling up with rust and gunk that will eventually result in a foul smelling, low pressure, unfit to drink water supply for your home. It’s even possible that you’ll develop leaks in the pipes that will cause rot, mold, and potential major damage to your home
Many times a re pipe is not required even with galvanized piping If the installer used a dielectric fitting or nipple to prevent ferrous and non ferrous metals coming in direct contact with each other.
For example many unscrupulous tradesmen think nothing of using a brass valve connected to a galvanized pipe which causes an electrolytic reaction.
Rather then spending a little more money and use a dielectric union to protect the piping
Also when a system is failing it is a good idea to find out why it has failed such as acidity of the water or minerals etc. so your not making the same mistake again
