Your plumbing system is one of the most important parts of your home. A leak or clog in a pipe can disrupt the entire flow of your day, and leave you with expensive damage that you'll have to have fixed. Thankfully, there are a few warning signs associated with pipes that need to be replaced, which can help you identify when you should contact a plumber before you have serious plumbing repairs to deal with.
Probably the best indication that your home's plumbing system has reached the end of its lifespan is if the water coming out of your faucets is discolored. Dark brown water points to rusting in your plumbing, which means that it is not safe to drink and that your plumbing has started to structurally degrade, which makes the chances of a leak much more likely. Other types of discoloration can also point to water supply contamination, which may not damage your plumbing but can make your water unsafe to drink: either way, water that is not clear should be inspected by a professional plumber.
Low Water Pressure
While low water pressure may seem like more of an annoyance while showering than anything else, it can actually point to serious plumbing issues. Your water pressure may be reduced either because your plumbing has leaks in it that is siphoning water out of your plumbing and into the interior of your home, or a clog in your plumbing that is blocking the flow of water. A clog, while not initially causing damage to your home, can quickly turn into a complete blockage, preventing water from flowing to your faucets, and building up pressure behind the clog, which can greatly increase the chance of a pipe bursting.
If you notice that the water coming out of your faucets and shower has a strange, earthy smell, it may be time to replace your home's plumbing. This bad smell is associated with bacteria growth in your pipes, which can happen normally over time due to age and use. Replacing your pipes can eliminate these bacteria and restore the cleanliness of your water supply.
Finally, the clearest sign that you need to have your plumbing replaced is if you notice mold growth anywhere in your home, especially when surrounded by water damage. This points to either a leak in you plumbing, or heavy condensation. Both of these are fairly serious plumbing issues that need to be addressed immediately, before they can cause further damage to the interior of your home.
