After the clogged drain, the water leak is the most common and persistent trouble affecting home plumbing. Leaks in pipes and valves creates water damage, lowers water pressure throughout a plumbing system, wastes water, and can even create unhealthy conditions. For example, you don’t want leaks in sewer lines allowing bacteria and other contaminants into your house, and even fresh water leaks can create the growth of harmful molds.
This list of leaky plumbing problems is one of the reasons you should never wait to call a professional plumber to fix a leak. Any plumber will tell you that there’s no such thing as a “minor” leak. A leak can be small, but the accumulation of water still causes plenty of damage. Small leaks often get the opportunity to create problems because people brush them off and delay calling for a pro to fix them.
