Most pipes have a relatively long lifespan, but their useful years can be compromised by a lack of maintenance, hard water, temperature fluctuations, low-quality fittings and joints, and shoddy installation. If your home is more than 60 years old, keep a close eye on the exposed pipes in your kitchen, bathrooms, and basement. Be on the lookout for obvious leaks as well as discoloration, stains, flaking, and dimpling, which are all signs of corrosion.
A good time to replace aging, exposed pipes is when you’re remodeling your kitchen, bathrooms, or basement. If you’ll be knocking down walls or repositioning major fixtures, you should replace pipes concealed in walls and floors as well.
