Watering the garden and lawn is one of the essential care practices required in all gardens. Remembering to water or learning how to water enough can be difficult when you are busy or forgetful. Installing an automatic irrigation system takes the watering responsibilities out of your hands. Automatic watering systems turn on according to a set time schedule, or when a rain sensor detects that the plants may require water.
Attach a check valve onto the outdoor faucet by screwing it onto the hose attachment threads.
Screw a hose bib onto the check valve.
Attach a hose bib manifold to increase the lines available from the house. Screw pressure reducers onto the end of each faucet.
Add an automatic valve to each of the faucets. Place the manifold so that the arrows on the body are pointing in the direction of the water flow.
Plug the irrigation system controller into each of the valves. Cords reach from the controller and plug into the valves. Mount the control system on a wall nearby or attach to the hose bib area using hooks.
Attach 1/2-inch polyethylene tubing to the end of each automatic valve.
Run the tubing to the garden, anchoring down the tubing with anchoring stakes. Place the 1/2-inch tubing along the garden for the best coverage.
Punch holes into the polyethylene tubing with a hose punching tool and insert a connector in each hole. Attach 1/4-inch tubing to the connectors.
Run lines of 1/4-inch tubing around plants in the garden. Cut the tubing near plants you wish to water and place an emitter at the end of the tubing to turn it into a sprinkler.
