What Causes Leaks in Pipes?


What Causes Leaky Pipes? Demystifying Common Plumbing Issues

Plumbing problems are an all-too-common occurrence for many homeowners. It can be difficult to identify what’s causing your plumbing woes, from clogged drains to leaky pipes.

In this blog, our team at Nautilus Plumbing dives into the four most common causes of leaky pipes. We’re sharing simple tips for preventing them from happening in the first place.

Clogged Water Lines

A clogged water line is one of the most common causes of leaky pipes. If a sink or shower has not been used in a long time, an accumulation of dirt and debris can cause a blockage in the water line that can lead to leaking.

To avoid this issue, regularly check your pipes and make sure all fixtures are draining properly. Contact a professional plumber immediately to clean your lines if you notice any slow drainage or hear gurgling noises from your drains.


Another common culprit behind leaking pipes is corrosion. This happens when water comes into contact with rusty metal piping over time and causes the pipe to corrode and eventually break down, leading to leaks.


Corrosion can be prevented if a professional inspect your home every few years. Consider replacing old copper or galvanized steel piping with more modern materials such as PVC or stainless steel. Also, be sure to use corrosion-resistant fittings whenever possible.

Incorrect Pipe Laying

Leaky pipes can also be caused by incorrect pipe laying. If pipes are not laid correctly or connected too tightly, they may develop cracks and holes, leading to leaks over time.

Cracks can be avoided in pipes by ensuring all plumbing connections are tight but not overly so; if necessary, use plumber's tape around connections before tightening them further for extra security. A professional plumber will check that pipe runs are laid out correctly before installation.

High Water Pressure

Finally, high water pressure is another common cause of leaky pipes. High-pressure levels can wear down piping over time, causing it to crack and leak. For this reason, it’s important to check your water pressure regularly using a pressure gauge so that you can adjust accordingly if needed (most homes should maintain 40-60 psi). You should also install a pressure-reducing valve to help ensure that water pressure remains at an appropriate level throughout your entire system.
