A DIY Guide to Fixing a Leaky Pipe Under Your Sink

If you’ve got a leaky pipe under your kitchen sink, you need to know that it can cause much larger problems than just an increased water bill. Over time, leaking water can damage your pipes and fixtures, cause wood rot inside your cabinets and even create dangerous, toxic mold. Unfortunately, many people experiencing the effects of a leaking pipe end up contacting a plumber first, not realizing that there are some simple DIY steps that they can take on their own to fix the problem. If you’ve found yourself in this situation, here are some tips from Benjamin Franklin Plumbing® of Dallas to help you stop the drip:

  1. Identify the Source: The plumbing underneath your sink is made up of a variety of pipes, including hot and cold water supplies, drain pipes and a P-trap. Additionally, some kitchen sinks may also include lines for a garbage disposal or a dishwasher. When investigating the source of the leak, keep in mind that water can run down a pipe and drip, meaning the location where you’ve spotted dripping water is not necessarily where the leak itself is.
  2. Tighten Connections: Using a wrench, ensure that all connections are tight, especially where you’ve found the leak. Over time, pipe connections can become loose and worn, and if tightening doesn’t solve the problem, you may need to replace a segment of the leaky pipe.
  3. Wrap Your Pipe’s Threads: You could also try turning of your home’s water supply, running the sink faucet until it stops, then turning the faucet off. Afterward, detach the leaking pipe and wrap the threads with plumber’s tape, then reattach and turn the water back on.
