Have you been considering installing a sprinkler system for your lawn? If so, you’re likely looking for cost-effective and easy-to-install options.

One of the most popular options out there is the poly pipe, which is made from high-density polyethylene and can be used for cold water supply lines.

But before you purchase any poly pipe for your sprinkler system, it’s important to check with your local building codes to make sure it’s permitted in your area.

Benefits of Poly Pipe

Poly pipe is a popular choice for DIYers looking to install their own sprinkler systems because of its affordability and ease of installation.

It’s also less susceptible to cracking or breaking due to extreme temperatures than other types of piping materials, making it a great option if you live in an area where temperatures drop drastically during the winter months.

Additionally, the poly pipe is resistant to corrosion and rusting, so it won’t degrade over time as other pipes might.

Drawbacks of Poly Pipe

While poly pipe has many benefits, there are also some potential drawbacks that should be taken into consideration before using this type of piping material for your sprinkler system.

For one thing, a poly pipe isn’t as flexible as other piping materials and can be difficult to fit into tight spaces or corners. Additionally, poly pipe tends to have a shorter lifespan than other types of pipes – about 10 years compared to up to 20 years for PVC or PEX piping materials.

That being said, if cared for properly (such as by avoiding chemical cleaners) these life spans can increase significantly!

Choosing the Right Type of Poly Pipe

Once you’ve determined that poly pipe is permitted in your area and decided that this type of piping material is right for your sprinkler system, it’s important that you select the right type of poly pipe for the job.

Make sure you consult with an irrigation specialist or contractor who can help determine which type will work best based on factors such as water pressure needs, temperature fluctuations in your area, and any additional considerations particular to your specific plumbing needs.

With the right information and guidance from experts in the field, installing a sprinkler system with a poly pipe can be an easy way to get the job done without breaking the bank!


Polypipe can certainly work well for many DIYer’s looking to set up an irrigation system but just like any other project involving plumbing – it’s important to do plenty of research first before purchasing any materials or tools needed for installation.

From double-checking building codes in your area to researching alternative options depending on size/location requirements – taking these steps ensures that your sprinkler system will last longer and perform better over time!
