Valve Box

When it comes to irrigation system installation and design, valve boxes play an important role, yet often aren’t given much thought. Valve Boxes provide protection from damage (children, animals, vandals, etc.), easy access for maintenance and repairs and hide unsightly irrigation components from sight. A well-designed valve box can make installations faster and easier while reducing the need for future maintenance.


We carry complete valve boxes along with valve box replacement covers and valve box extensions. Whatever you need, we have you covered!

The key benefits of Mais VB Series Valve Boxes are:

• Strength and stability
• Environmentally friendly
• Flexible installation

Disk Filters

Water filtration is important for all irrigation systems. Now before someone argues with me, yes, some sprinkler systems are used to spread solids, such as treated sewage, for disposal. But even those in my experience have incorporated some form of filtration upstream of the system to prevent solids which are too large from entering the system.

Disk filters are a cross between a screen filter and a media filter, with many of the advantages of both. Disk filters are good at removing both particulates, like sand, and organic matter. A disk filter consists of a stack of round disks. The face of each disk is covered with various sized small bumps. A close up view of the bumps reveals that each has a sharp point on the top of it, somewhat like a tiny pyramid. These bumps are very small, thus a typical disk looks a lot like the old vinyl 45 RPM records! Because of the bumps, the disks have tiny spaces between them when stacked together. The water is forced between the disks, and the particulates are filtered out because they won't fit through these gaps. The organics are snagged by the sharp points on the bumps. For automatic cleaning of the filter the disks are separated from each other which frees the debris to be flushed out through a flush outlet. For less expensive disk filters you must remove the disks and hose them off.
