Some thoughts about starting an simple irrigation project
So I want to irrigate a narrow perennial bed. From what I can research, I need:
- A splitter to split the water so I can continue to use the hose.
- Some sort of timer device to time the control of water.
- A pressure controller
- A backflow preventer.
- A filter
- A drip line or soaker.
Most of the components are constant (filter, etc). Some of the other components requires some choices. For example, if I set up a drip line, I can probably direct the water to the plant directly. However, a soaker hose seems easier to setup initially and some of the plants are sort of clump spreaders.
The second issue is the timer device. The cheapest are wind up mechanical devices, but I don't trust them. What if the mechanic blows up and leave the water running? The battery ones are similar to windup but they use batteries. Finally, there are electronic ones you can program. Are they more reliable. What if they malfunction, does the water shutoff? Finally, I wonder if they have ones that can detect rain, so if it has rain, it won't dump out any water.
