NDS 117BC 15″ x 22″ Jumbo Valve Box
The NDS 117BC provides substantial protection for irrigation components such as valves and control zone kits. It offers easy access for maintenance and features ICV lettering on the cover. This box helps maintain a clean, secure underground environment, with reinforced ribs to resist impact and heavy use. Best for large residential or small commercial systems with multiple valves and control modules. Caution: larger footprint means more trenching space is required.
NDS 107BC 6″ Valve Box with Cover
This compact option protects irrigation components in tight spaces. The 9-inch tall box has ICV lettering and a durable black/green cover, offering a clean underground environment and resistance to pedestrian traffic and lawn equipment. Best for small yards or retrofit projects where space is at a premium. Limitation: smaller size may not fit larger valve configurations without planning installation layout.
NDS 113BC 14″ x 19″ Standard Series
This standard-size box uses UV-treated polystyrene for durability and weather resistance. It provides ample open surface area, supporting medium-duty installations and higher flow demands. Suitable for shared drainage, stormwater management, and ADA-conscious setups. Best for projects requiring medium load tolerance and easy fabrication with standard basins. Caution: UV exposure can still degrade if not installed with shielded exposure.
4 Pcs 113c Series 12 x 17″ Covers
This kit includes four sturdy PP valve box covers with a 12 x 17-inch external footprint. The design prioritizes a snug, one-click installation and long-term protection. Best for multi-valve setups or when replacing aging covers in larger landscapes. Limitation: may require compatible base boxes for a secure fit in some installations.
12-Pack Durable PP Valve Boxes
This 12-pack provides a cost-effective solution for large projects or expansive sprinkler systems. The polypropylene construction handles sun, rain, and outdoor wear, while an anti-slip surface improves safety in wet conditions. Best for large landscapes or contractors who need multiple enclosures. Caution: bulk packaging means managing inventory and storage carefully.
Buying Guide
What size do I need?
Choose based on valve and controller footprint. Larger installations benefit from bigger boxes with more open surface area for airflow and drainage. Smaller yards can use compact boxes to save space and trenching effort.
What material should I pick?
Polystyrene and polypropylene offer weather resistance and UV stability. UV inhibitors prevent fading and cracking, extending service life in sun-heavy areas. Durability depends on object size, load exposure, and traffic near the site.
How important is the cover design?
Overlapping green covers with ICV lettering aid quick identification and maintenance access. A secure, tight-fitting cover reduces debris intrusion and vandalism while allowing easy removal for service.
What about installation considerations?
Ensure your trench depth, open surface area, and load tolerance match the box rating (Class B or similar). ADA compliance and compatibility with basins, risers, or adapters simplify drainage and stormwater management.
How many boxes should I buy?
For large properties, a mixed approach works well: a few standard-size boxes for core zones and several compact boxes for tight spaces or secondary zones. Multi-pack options lower per-unit costs for large projects.
