Galvanized water and/or drain lines have a typical life expectancy of 40 – 60 years. Galvanized piping was typically installed in Northwest Ohio homes up until 1960 or so. The interior surfaces of this pipe corrodes over time and the buildup reduces the water flow/drainage or the pipe will simply rust/corrode through and leak, especially at joints. Sometimes it is difficult to run multiple fixtures or the drainage will become noticeably slower. If there is any galvanized piping found during your home inspection, it would be prudent to budget for replacement. If there are signs of leaks, corrosion, or reduced pressure or drainage, it should be replaced with plastic or copper. Please note that if the main water line from the street is galvanized, this is the homeowner’s responsibility and will involve a significantly higher replacement cost. Please also note that softening the water typically extends the life of galvanized piping and hard water deteriorates it much quicker.
