Orbit's WaterMaster is a complete line of easy-to-use underground irrigation products, including sprinkler timers, valves, accessories, tools, and a wide variety of sprinkler head options. WaterMaster products are innovative, easy-to-use, and engineered for durability and performance.

This jumbo, 20-inch irrigation valve box is designed to provide maximum protection and convenient access to all in-ground irrigation components. They are large enough to house up to six 1 inch valves or drip control zones. A unique truss design in the bottom of the lid promotes maximum strength across its substantial surface area. With its 12 inch height, the box reaches well into the frost-free zone of most climates. With the addition of one or more extension boxes, it can easily accommodate 18 inch mainline projects as well. Pre-built mouse holes allow for faster placement of up to 2 ½ inch pipe. A T-top locking lid makes it quicker to take the lid on and off, resulting in faster service times. The unit is 100% recyclable and may contain pre and post-consumer recycled materials.
