Exploring Inground Box/Wall Timer Irrigation Systems: Pros and Cons

Welcome to this month's blog, where we delve into the advantages and drawbacks of inground box/wall timer irrigation systems. This sophisticated irrigation setup comprises several components: an in-ground box housing valves controlled by solenoids, a backflow preventer, a filter, and a wall-mounted timer dictating the opening and closing of valves. Typically, the water source is an underground line branching off the main water line, with a pressure reducer often installed within the irrigation box to ensure optimal system pressure. Known for their professional-grade quality, reliability, and seamless integration into landscapes, these systems can accommodate anywhere from a single zone to over a dozen.

While we often recommend this system for most clients, it's essential to consider its drawbacks:

  1. Upfront Cost: The initial investment for this system can be steep. However, the reliability and performance often justify the expense.

  2. Professional Maintenance: Due to its complexity, it's highly advisable to have a professional handle the activation and deactivation of the system, especially during winterization. Improper shutdown can result in costly repairs.

  3. Solenoid Maintenance: Over time, solenoids may wear out and require replacement, incurring additional costs.

  4. Backflow Preventer Maintenance: Backflow preventers can develop drips due to sediment accumulation, necessitating disassembly and cleaning. It's worth noting that certain jurisdictions, like Santa Fe, mandate backflow preventers to prevent cross-contamination.

While these downsides are worth considering, the overall performance and seamless integration of inground box/wall timer irrigation systems often outweigh the drawbacks, making them a preferred choice for many landscaping needs.
