Curved pipe joints link straight sections together to direct water throughout your home, and they are especially vulnerable to pressure from the high-pressure water or extreme temperatures in your plumbing system over time. These connection points are the weakest points of your plumbing system. As the welds age, they become weaker and are often the cause of leaks within your walls. Also, consistent changes in water pressure also cause the joints to flex. It’s best if you can identify any problems with worn pipe joints early on because it’ll be much easier for plumbers to fix them before there’s significant damage!
