Sprinkler Parts Glossary
Sprinkler jargon, translated. Search plain-English definitions of the parts and terms you'll hear when talking about your irrigation system.
- Action Manifold Pipes & Fittings
- A modular valve-manifold system that uses reusable fittings and O-ring seals. Individual valves or manifold sections can often be serviced without cutting apart the entire assembly.
- Adapter Pipes & Fittings
- A fitting that changes pipe size, material, or connection type, such as slip-to-thread or PVC-to-poly.
- Adjustable Emitter Drip
- An emitter whose output can be manually increased or decreased. It offers flexibility but can be harder to keep uniform than fixed-flow emitters.
- Air Compressor Service & Repair
- A machine that supplies compressed air. Irrigation winterization requires appropriate airflow and controlled pressure to clear the system safely.
- Anti-Siphon Valve Valves & Zones
- A control valve with a built-in atmospheric vacuum breaker. It must be installed above the highest sprinkler it serves and is not the same as a whole-system RPZ or PVB.
- Arc Heads & Nozzles
- The portion of a circle watered by a sprinkler, usually measured in degrees. A 90-degree arc is a quarter circle, 180 degrees is a half circle, and 360 degrees is a full circle.
- As-Built Plan Service & Repair
- A drawing or record showing the actual installed locations of pipes, valves, heads, wiring, and other system components.
- Atmospheric Vacuum Breaker (AVB) Water Supply
- A simple backflow device that allows air into the piping to stop backsiphonage. It cannot remain under continuous pressure and must be installed downstream of the control valve and above all outlets it serves.
- Backflow Preventer Water Supply
- A device that prevents irrigation water from flowing backward into the home or public drinking-water supply. A backflow preventer is the general category; RPZs, PVBs, and double-check assemblies are specific types.
- Backpressure Water Supply
- Pressure on the irrigation side becomes greater than the pressure in the drinking-water supply, potentially pushing irrigation water backward without proper backflow protection.
- Backsiphonage Water Supply
- A pressure drop in the water supply creates suction that can pull irrigation water backward toward the drinking-water system.
- Ball Valve Water Supply
- A manual shutoff valve that uses a drilled ball inside the valve body. A quarter-turn of the handle opens or closes the valve, making it fast and easy to operate.
- Barbed Fitting Drip
- A fitting with ridges that grip the inside of flexible poly or drip tubing.
- Blank Drip Tubing Drip
- Tubing without built-in emitters. Individual emitters or smaller distribution tubes can be added wherever plants need water.
- Blowout Port Water Supply
- A fitting where an air compressor connects so water can be blown out of the sprinkler system during winterization.
- Booster Pump Pumps
- A pump added to an already pressurized supply when additional pressure is needed. A booster pump cannot create more water than the supply pipe can deliver.
- Boring Pipes & Fittings
- Creating a path beneath a sidewalk, driveway, or other hard surface so pipe or wire can pass underneath without removing the concrete.
- Bottom-Inlet Valve Valves & Zones
- A control valve configured so water enters through a port on the bottom rather than through a side inlet. These valves are often used in compact or modular manifolds.

- Centrifugal Pump Pumps
- A common irrigation pump that uses a spinning impeller to move water. Many centrifugal pumps must be primed before operation.
- Check Valve Water Supply
- A valve that allows water to travel in only one direction. Check valves are used inside backflow assemblies and elsewhere in irrigation systems to prevent reverse flow or low-head drainage.
- Check-Valve Head Heads & Nozzles
- A sprinkler head with an internal check valve that holds water in the lateral line and helps prevent drainage from low heads.
- Clogged Nozzle Service & Repair
- A nozzle blocked by dirt, sand, grass, or mineral deposits, resulting in reduced flow or an uneven spray pattern.

- Discharge Line Pumps
- The pipe carrying pressurized water away from a pump and into the irrigation system.

- Goof Plug Drip
- A small plug used to seal an unwanted or misplaced hole in drip tubing.
