Durable in harsh weather

We have had these in the ground through two winters and a very hot summer. No cracking or fading observed. The green color blends well into the turf.

Standard fit for commercial jobs

I use these on almost all my commercial lawn projects. The 6-inch size is perfect for single valve setups. They stack well with extension rings if you need extra depth.

Great quality, slightly heavy

The HDPE material feels very durable and should last for years. The only downside is that the 10-inch version is a bit heavy to maneuver alone when installing deep, but otherwise excellent.

Easy DIY installation

As a homeowner, I was worried about installing underground valves, but this box made it simple. Clear instructions and standard connections made the weekend project a success.

Exactly what I needed

Replaced an old cracked concrete box with this plastic one. Much easier to access the valve for maintenance. The lid stays secure even after mowing over it.

Perfect for our orchard irrigation

We installed twelve of these 10-inch boxes for our new drip line system. They are sturdy, easy to assemble, and the lid fits snugly to keep dirt out. Highly recommended for agricultural use.

5 FAQ

Q: Does this box come with the extension rings included?

A: The base unit includes the box body and lid. Extension rings are sold separately to allow for custom depth adjustment during installation.

Q: Is this suitable for potable water lines?

A: Yes, the HDPE material used is safe for contact with potable water systems, though the box itself is primarily designed for protecting valve mechanisms.

Q: What is the maximum depth this valve box can be installed?

A: There is no strict maximum depth as long as you utilize the compatible stacking extension rings. Ensure proper compaction around the box for stability at greater depths.

Q: Can the 10-inch model support vehicle traffic if installed in a driveway?

A: Yes, provided you purchase the specific H-20 traffic-rated lid option available for the 10-inch model. The standard lid is for pedestrian or lawn traffic only.

Q: How do I cut the bottom knockout holes for pipe entry?

A: The pre-scored knockout holes can be removed using a standard utility knife or a fine-tooth saw. Please wear safety glasses when cutting.
