When it comes to drainage solutions, it's easy to get lost in the vast amount of information and opinions available online. Recently, one of our clients was unsure whether the PVC pipe we use is better than corrugated pipe—a question sparked by a YouTube video that suggested corrugated pipe might be the better option.
Let us take a moment to explain why PVC is in fact the superior choice for most drainage applications, especially when compared to corrugated pipe.
1. Durability and Longevity
Simply put, PVC, or polyvinyl chloride, is renowned for its durability. It’s a rigid material that can withstand significant pressure and environmental factors without compromising its structural integrity.
Over time, corrugated pipes, typically made from polyethylene, are prone to crushing or deforming, especially when buried deep under. But PVC pipes can withstand the pressure and last longer. As you probably know, a crushed pipe can cause blockages or reduce water flow, leading to potential flooding or damage to your property.
With PVC, homeowners can alleviate much worry about a pipe collapsing under pressure—whether from soil or water volume.
2. Smooth Interior for Efficient Flow
A critical aspect of any drainage system is the ability to move water efficiently. PVC pipes have a smooth interior surface, which reduces friction and allows water to flow quickly and smoothly. This minimizes the risk of blockages, particularly in areas where debris may enter the drainage system.
On the other hand, most corrugated pipes have ridges inside, which can trap debris, dirt, and sediment over time, increasing the likelihood of clogs and backups. A smooth option is preferable.
3. Ease of Maintenance
Stemming from the above, PVC requires less maintenance compared to corrugated pipe. Again, because PVC is smooth inside, it is less likely to accumulate dirt and debris that can lead to blockages.
And, if there is ever a need for maintenance or cleaning, PVC's straight, rigid sections make it much easier to access and clean than corrugated pipe (which tends to bend and warp, making maintenance more difficult and costly).
4. Root Intrusion Resistance
A common issue with drainage pipes is root intrusion. Over time, tree roots can find their way into pipes in search of water, causing significant blockages or even breaking the pipe.
Corrugated pipes, which often have small gaps at the joints that roots can exploit, usually fare worse against Mother Nature than PVC pipes, with their seamless joints and sturdy construction.
5. Installation Flexibility
While corrugated pipe is flexible and easier to bend around obstacles, this flexibility comes with downsides—namely, a lack of structural integrity in certain situations.
So while PVC may be more rigid, it can be cut and put into place precisely, ensuring a long-lasting, tailored solution for any drainage project.
Plus, PVC’s rigidity ensures that once it’s installed, it maintains its shape and flow capacity for years to come.
Final Thoughts: Trust Proven Solutions
Corrugated pipes may seem like an attractive option due to their lower upfront cost, but you should also consider the long-term expenses.
PVC, while initially more expensive, is likely to save you money in the long run. Its durability, low maintenance needs, and resistance to common drainage issues make it a better investment.
