I have a Porter Cable 150 psi. How do I go about blowing the lines? I usually have my landscaper do it. He connects the compressor to the outside water faucet once I turn off the water line from inside. I would need the connector used to attach to the outside water facuet so I could connect the compressor to it correct? How do I open each zone? Is the black screw on each valve turned to open each zone line? Thanks
The Irritrol PC controller is just about the best one. It interfaces with your computer, wirelessly, and has a remote you can carry around to change programming or test individual circuits.
