Drip Irrigation Parts & Accessories
Pressure regulators, flush valves, and bug caps protect a drip system from the three things most likely to damage it: too much pressure, sediment buildup, and insects nesting inside open emitters. A pressure regulator keeps flow within the range drip components are built for, preventing blowouts at joints and fittings. Automatic flush valves clear sediment from the end of a line before it reaches emitters, and bug caps seal emitters against insects looking for a water source. Shop the parts that keep an existing drip system running clean.

Drip components are built to run at low pressure — usually far lower than what comes out of a standard hose bib or irrigation valve. A pressure regulator installed at the head of the system steps incoming pressure down to a safe, consistent range before it reaches tubing and emitters, which is what prevents a system from blowing apart at a fitting or joint the first time the zone runs at full valve pressure.
Sediment is the other main threat to a drip system, and it's a slower, quieter problem than a pressure blowout. Grit and mineral buildup travel through the line and settle at low points or inside emitters, gradually reducing flow until a plant that used to get consistent water starts showing signs of underwatering. An automatic flush valve, installed at the end of a line, opens briefly at the start of each cycle to flush sediment out before pressure builds, which keeps buildup from accumulating in the first place.
Bug caps solve a smaller but common problem: insects, especially ants, are drawn to the moisture inside an open emitter and can nest inside it, blocking flow entirely. A bug cap seals the emitter opening between watering cycles while still allowing water through when the system runs, which is a low-cost way to prevent an otherwise healthy emitter from failing due to something crawling into it.
None of these parts water a plant directly — they protect the parts that do. A regulator, flush valve, or set of bug caps is usually installed once during setup and then largely forgotten, which is exactly the point: they're working in the background to keep Drippers/Emitters and Tubing functioning as designed. If you're building a system from scratch rather than protecting an existing one, Control & Conversion Kits bundle a regulator with the fittings needed for a spray-to-drip conversion. The Learn HUB has maintenance guides for keeping a drip system running clean season after season.
