How to Cut Sprinkler Riser

Sprinkler risers are an essential part of any irrigation system. They are vertical pipes that connect the underground mainline to the sprinkler heads, allowing water to flow from the mainline to the sprinklers. Over time, these risers may need to be cut or replaced due to wear and tear, changes in landscape design, or other reasons.

How to Cut Sprinkler Riser

Cutting a sprinkler riser may seem like a daunting task, but with the right tools and techniques, it can be done quickly and easily. In this guide on how to cut sprinkler riser, we will walk you through the steps of cutting a sprinkler riser, from gathering the necessary materials to making a clean cut.

Gather Materials

Before you begin, make sure you have all the necessary tools and materials. These include:
