Why is galvanized pipe sometimes a problem?
It corrodes on the inside. As water passes through, corrosion deposits build up inside and partially block water flow. Older pipes may be so corroded that even a pencil would not fit through the center of the pipe. Running water through a corroded pipe is like sipping through a coffee stirrer instead of a soft drink straw. Less fluid flows through. In most cases you cannot clean the inside of the pipe without causing leaks. Can I test for corrosion? • Run three faucets in your house at the same time. If flow decreases significantly at the first tap when you turn the others on, your pipes are probably corroded. • If you have galvanized pipe and water is discolored when you first run the tap, you may have a corrosion problem. Let your tap run for 30 seconds or more – until the water feels noticeably colder. This flushes standing water out of the pipes and replaces it with fresh water. What can I do about a flow problem? • Run water from only one tap at a time. Avoid watering the lawn whe
