  • Laying the water pipe in the garden: tips for connecting the water supply to the garden irrigation system

    Open trench in a paved area with exposed cables, pipes, and a water pipe in the garden, surrounded by loose soil, bricks, and paving stones—signs of ongoing underground utility or lawn irrigation work. www.commaik.de

    Laying a water pipe in the garden is a crucial step for efficient garden irrigation and reliable lawn watering. In this project, the pipeline had to be routed under an existing cobblestone path. The paving stones were removed, a trench dug and the pipes laid together with empty conduits for control and power cables. In addition to the right choice of material, frost resistance also plays an important role. The entire process – from planning and leak testing to restoring the sidewalk – is described in detail in this article.

  • Installing lawn irrigation: Valve box, Hunter solenoid valves and Rain Bird water distribution in detail

    Lawn irrigation system components, including pipes, valves, and wiring, are laid out on the ground next to an open valve box in a grassy area. A green garden hose and plastic cover are also visible. www.commaik.de

    Efficient lawn irrigation starts with a well-planned valve box, which forms the heart of the entire garden irrigation system. In this article, I will show you how I set up my valve box, selected the right components and optimized the water distribution. This involves installing the manifold, connecting the Hunter solenoid valves and laying the pipes safely. I also explain why I rely on a modular design so that the system can be flexibly expanded at any time. All the details on material selection, pressure resistance and optimum connection technology can be found here.

    Robotic lawn mowers without boundary wires make lawn mowing smarter and more flexible. Instead of perimeter wire, they rely on GPS, RTK navigation and camera technology – this saves installation effort and offers more precise control. My detailed comparison shows which models are convincing in the test, where the strengths and weaknesses lie and which robotic mower is best suited to which garden conditions.
