I have been operating my garden irrigation for several years now and it has done an excellent job in the great summer of 2018.
Sprinkler – Hunter or Gardena
Deciding for my opinion were our holidays in Florida. All the houses have garden irrigation systems that irrigate the large gardens every night. Very precisely, the pop-up sprinklers have done their job and irrigated the intended area. Predominantly Hunter products were installed there. In various discussions with homeowners, the longevity and low maintenance of the sprinklers has become clear. Even after years of daily use, the sprinklers perform their work precisely and also the spring pressure in the riser of the transmission controller does not diminish. I can also confirm this with my use for several years (no daily use, but very frequent in summer) in the garden.
Based on the experiences from Florida, I decided for the sprinklers from Hunter. I have seen the Gardena sprinkler in the handyman market and read a variety of forum posts about them. Finally, I preferred the Hunter sprinkler product quality.
In addition, I was convinced by the great radius of the Hunter sprinklers and the various spray nozzles for the close range (MP Rotator, Pro-Spray nozzles with fixed sector, adjustable nozzles, special nozzles).
Water Pipeline – Hunter or Gardena
After the decision of the sprinklers had fallen, I now needed to decide which water pipeline I want to use. There is a big difference to the situation in Florida. In Germany, winter temperatures reach minus degrees and the water freezes in the water pipeline. Thus, drainage is an important issue to protect the pipeline from damage. If you deal with the Hunter water pipeline, you quickly get to the area “blow-out method” when draining. Since I do not have an air compressor, this method was not suitable for me.
The second possibility of drainage via manual valves, which are installed at the lowest point, was the solution for me. Gardena offers an automatic valve for drainage. In the event of a pressure drop in the pipeline below 0.2 bar, the valve opens automatically. In other words, in preparation for the winter, I can disconnect the water supply in the garage from the pipeline and the existing pressure drops. Thus, the water can flow through the Gardena drainage valve into the soil. This has not resulted in any damage to my water pipeline in the last four winters.
Magnetic valve – Hunter or Gardena
Magnetic valves are required to control the individual pipeline path. Both manufacturers offer systems with 24V AC voltage. Also, the valves of both manufacturers can be disassembled and repaired if necessary. Spare parts can be ordered individually on the internet. In addition, both manufacturers offer a manual opening of the valves to manually activate irrigation. If you do not use the solenoid valves in a building, like a garage or basement, you need appropriate valve boxes to put the valves into the ground.
For my irrigation solution, I have chosen the Hunter PGV-101G, because these valves are cheaper priced.
Planning Tool – Hunter or Gardena
Another reason for using the Gardena Pipeline has been Gardena’s planning tool. The company Hunter provides only a planning manual. With the Gardena planning tool you get a good planning blueprint as well as a list of the required material. I have ordered the corresponding material for the pipeline from Amazon. But int the end the implementation was different than planned. I needed additional connectors (especially L-pieces) that I could buy at short notice in my well-stocked hardware store. But even with those unplanned circumstances, I still managed to install the whole system in one day of work.
