6 warning signs your cast iron plumbing stacks need to be replaced:
-
Slow drainage. If your toilets or sinks have started to drain slowly, and normal unclogging procedures aren’t working, you could have sediment buildup that is clogging your pipes.
-
Discolored water. If your faucet or toilet water is brown, orange or otherwise discolored, your cast iron pipes could be significantly rusted. Cast iron is known to have rust issues, so this should be checked by a professional plumber immediately.
-
Wet spots. If your interior walls start to show wet spots, your plumbing stack could have sprung a leak. Since the pipe diameter of a plumbing stack is fairly wide, a major leak could be a huge problem. Don’t wait for minor leaks to turn into significant damage when the pipe bursts later.
-
Bad odor. Your plumbing stack is normally an airtight system, with noxious gas expelled through a vent system in your roof. If you consistently notice a foul smell in your home, a leak in your plumbing stack could be the culprit. This is a potentially dangerous problem and certainly lowers the quality of life for residents. It is something that needs to be dealt with promptly.
-
Mold. If your interior walls are showing signs of mold, a leak in your plumbing stack could be providing the moist environment. It really could be leaks in any of your piping, but the situation would be especially dire if it were the stack.
-
Barnacles. No, not the barnacles you’d find on a ship. It’s just another name for tiny rust spots appearing on the pipes of your stack. These spots weaken the structural integrity of the metal and lead to leaks, or potentially something worse. It can be difficult to notice this if your plumbing stack isn’t normally exposed, but if for any reason you see these spots appearing, you should call a plumber. This issue can then be resolved without a leak actually happening.
