Winterization
Although you could install drain valves, they can be unreliable and hard to find once the system has been completed. An air compressor is more effective. Shut off the inside valve and blow out each zone using compressed air.

Head Start
Sprinkler head for a small area
There are a number of sprinkler head options, depending on the size of the area being watered and the types of plantings. While sprinkler heads differ from manufacturer to manufacturer, the basic mechanisms are the same. Make sure water patterns overlap to ensure complete coverage.
Large areas
Spring-loaded pop-up rotary heads cover a radius between 15' and 40', depending on the model. They come with several nozzles (from 0.5 to 12 gallons per minute), so their versatility is an advantage where low water pressure is an issue, and they have adjustable arcs from 30° to 360°.
Gear Drives: quieter than impact heads (no more “ticktickticktick”), with adjustable spray patterns
Impact Heads: recommended for rural areas; with no filter they work well with pond, river or stream water where “dirty water” might otherwise clog a nozzle
Medium areas
Suitable for Lawn areas and around larger garden beds.
Fixed Pattern: available in 2" or 4" versions with spring-loaded pop-ups. Patterns include side, centre or end strip, as well as a square pattern; range is typically about 24', depending on the nozzle used
Shrub Head: sprays in a circular pattern, adjustable from 90° to 360°; usually installed on risers to clear shrubs or taller plantings; also available in spring-loaded pop-ups
Small areas
Used to flood flower beds, groundcover or “spot water” particular trees and shrubs.
Mushroom Bubbler: adjustable from full flow to light trickle; sprays 360°, maximum 4' radius
Stream Bubbler: multi-stream patterns, with a range of jets from 90° to 360°. Maximum radius is typically 4'. A strip pattern is also available
