Some deliver as little as one half gallon of water per hour while others deliver up to 10 gallons per hour. Some emitters are adjustable to deliver different rates of water. Sprinkler emitters also are available in various flow rates as well as with different spray patterns and coverage areas. While these systems need more planning, they are neither expensive or difficult to install. In most cases, no special tools or skills are needed.
Plastic pipe is punched with an inexpensive tube punch that assures the proper hole size.
Emitters or spaghetti tubes snap into the hole. No gluing or soldering is required. Because the holes are small, they can easily be plugged if you put one in the wrong place. Some systems come with pre-assembled emitters at regular intervals. Drip systems require periodic maintenance.
