If you own a home or are buying a home that is more than 50 years old then you might want to read this article. Galvanize water piping corrodes from the inside out. Homes that are 50 years or older and have not had the water piping removed and converted to copper piping will possibly start showing signs of corrosion. I was hired for a home inspection in Downers Grove, Illinois that happened to be 65 years old and had galvanize piping for the water supply lines and the volume of water through these pipes was reduced greatly due to the rust that had taken over the interior portion of the piping.
The pressure of the water supply to the home was 50 psi which is good. Most people think that their plumbing pipes preasure what causes the issues. The real issues is the volume or area of the piping has been reduced because of the rust inside the pipe. What then happens is the flow is reduced because now you are trying to get the same amount of water through a much smaller pipe. The Downers Grove home inspection had issues with all of the water piping but the hot water lines were dramatically worse than the cold water supply. This is due to the fact that the water has been heated and changes the composition of the water so slightly and allows air to rust the interior of the galvanize pipe.
There are contractors that will try to blow out you water supply pipes but this is a patch at best and removal of galvanize piping and installation of copper piping is the only proper repair for this issue.

Generally replacement of galvanize piping to copper water piping can cost any where from $2500.00 – $10000.00 depending on how many bathrooms, laundries, kitchens, wet bars and hose bibs you have.
Before you hire a plumbing contractor to come out and look at your piping try this quick remedy. Go to a sink that has poor pressure remove the aerator. The aerator is the part of the faucet where the water comes out. You can unscrew this part and see if there are particles of rust. If you see this and your pressure of water is low than you will probably need piping replacement. This is how I determined that the home inspection in Downers Grove would need water piping replacement.
As you can see there can be a multitude of reasons that you are having issues with your water piping in your home. If you find your self needing further assistance with this issue please contact me at ~ http://www.pinnaclepropertyinspection.com/about-jim-kolke.html.
