Installing Garden Watering Systems

Installing Flexible Garden Watering Systems

  1. Flexible garden watering systems operate on low pressure, so it is necessary to fit a pressure regulator and water filter on the the pipework just after it leaves the main supply point to adjust for the correct pressure.
  2. Lay out the lateral hose pipes and attach them to the main supply hose, following your original plan. When they are securely attached, run water through the system to flush out any debris.
  3. Drill holes in the main hose where they are needed. Insert the outlets or the transfer points. Attach points wherever they are required, taking into account the different watering requirements of your plants.
  4. Complete the entire hosepipe run, flush out the system a second time, ensuring that all outlets are working. The system can be covered, but ensure the ends of the small diameter tubing remain above ground.

Installing Fixed Garden Watering Systems

  1. To install fixed garden watering systems, you will need to mark out and stake the area of the garden you want irrigated, then dig a trench 20cm (8in) deep. Line the bottom of the trench with sand or sieved soil, keeping it as level as possible. Remove stones and any pieces of root.
  2. Lay the main pipe at the bottom of the trench, then fit the anti-siphon or non-return valve at the point where you are taking the supply off the main. It is important to ensure that the join is watertight.
  3. Attach the spray heads to the main pipe wherever they will be needed. Attach elbows and Ts for the branch pipes. Allow the welded joints to dry out for at least six hours, but for safety preferably longer.
  4. Once all the joints have set hard, turn on the water supply to check the anti-siphon device, to flush out any debris that may have got into the pipes, and to check for any leaks that may exist in the system.
  5. Once you are satisfied that everything is working well, and there are no leaks, back-fill all the trenches with soil above ground level, taking care not to clog spray heads with loose earth or the system will not work.
  6. With a timber beam or some similar object, tamp and firm down the soil around the spray heads, leaving them about 2.5cm (1 in) above the surface. Take great care not to hit the heads as you do so.
