DIY Underground Irrigation: Essential Orbit Tools for a Professional Installation

Underground irrigation systems offer a convenient, water-efficient way to keep your lawn and garden healthy without dragging hoses around. While professional installation can be costly, many homeowners successfully take on the project themselves with the right tools and components. Orbit Irrigation provides a comprehensive range of products designed to simplify every step of the process, from trenching to final setup.

This buying guide focuses on the essential tools you need for a DIY underground irrigation installation. Whether you are laying new PVC pipes, installing automatic valves, or wiring your system to a smart controller, having the right equipment makes the job easier and more reliable. Let’s walk through the key items that should be in your installation toolkit.

The Right Cutting Tool for PVC Pipes

Clean, square cuts are critical when working with PVC pipes for underground irrigation. A jagged or angled cut can lead to poor glue joints, leaks, or weak connections. Orbit’s 1/2" to 2" PVC Cutting Tool 26190 is designed to handle pipes up to 2 inches in diameter with a ratcheting mechanism that provides clean cuts with minimal effort. The ergonomic handles reduce hand fatigue during multiple cuts, and the durable steel blade stays sharp through many installations.

Whether you are cutting main supply lines or branch laterals, this tool ensures precise cuts every time. It works on both Schedule 40 and Schedule 80 PVC, making it versatile for residential and light commercial projects. Investing in a dedicated PVC cutter rather than relying on a hacksaw saves time and improves the quality of your pipe joints.

Selecting Automatic Valves for Zone Control

Every underground sprinkler system relies on automatic valves to control water flow to different zones. A quality valve must withstand constant water pressure, open and close reliably, and be easy to install underground. The 3/4 inch L-Series Automatic Inline Sprinkler Valves | 57280 are a popular choice for DIYers due to their robust construction and simple maintenance. Features like a manual bleed screw, flow control adjustment, and a durable thermoplastic body make them suitable for direct burial or valve box installation.

When choosing valves, consider the number of zones your system requires and the flow rate of your main line. The L-Series valves are available in 3/4-inch and 1-inch sizes, and they pair well with Orbit’s manifold kits for a tidy installation. Proper valve selection ensures even watering and reduces the risk of water hammer or pressure loss.

Wiring Your System with Sprinkler Wire

Connecting your automatic valves to the timer requires reliable, weather-resistant sprinkler wire. Standard thermostat wire often degrades quickly underground, so using a purpose-built wire like the 5-Strand x 50' UF/UL Sprinkler Wire 57094 is essential. This wire is designed for direct burial, featuring UV-resistant insulation and solid copper conductors that resist corrosion. The 5-strand configuration allows you to control up to four zones (plus a common wire), with extra strands for future expansion.

Proper wiring also includes using waterproof connectors at each valve splice and labeling wires clearly at the controller end. Orbit’s sprinkler wire comes in various lengths and strand counts, so you can choose the right one for your system size. Using the correct wire prevents intermittent valve operation and extends the life of your irrigation control system.

• Always use direct-burial rated wire for underground runs to avoid signal loss and corrosion.
• Leave a service loop of wire at each valve box to allow for future repairs or replacements.

Additional Tools to Complete Your Toolkit

Beyond cutting, valves, and wire, a few extra items will streamline your installation. A trenching shovel or a powered trencher makes digging channels for pipes much faster. A pipe reamer or deburring tool cleans the inside of cut PVC to prevent glue blockages. For testing the system after assembly, a simple pressure gauge helps confirm you have no major leaks before covering the trenches.

Orbit also offers accessories like hose menders and repair parts that come in handy if you accidentally nick a pipe or need to make adjustments. While not strictly required for a first-time install, having a few spare fittings and a tube of PVC primer and cement on hand can save a trip to the store.

Building your own underground irrigation system is a rewarding project that saves money and gives you control over your watering schedule. Start with reliable tools that make the job easier and more precise. The 1/2" to 2" PVC Cutting Tool 26190 is a simple but essential first step—grab one today and take the first step toward a greener, smarter lawn.
