Fit and feel

Good match:

This emitter pack fits gardeners building or refreshing drip routes around vegetables, herbs, flowers, shrubs, patio containers, and greenhouse benches.

Measured water points for drip routes

The Rain Bird SW20-30PS is a 30-pack of 2 gallon per hour drip irrigation emitters. Each emitter creates a measured water point along a compatible drip route for selected plants, planting pockets, containers, shrubs, or bed sections.

That measured flow makes the route simple to observe. A gardener can run water, watch the soil darken around each emitter, and adjust placement when a plant shifts or grows.

The 2 GPH flow suits clear plant zones

The 2 gallon per hour output is useful around plant zones that need a defined drip point. The pressure-compensating design is made to support steady emitter output when the rest of the setup is prepared with clean tubing, suitable pressure, and a reachable filter.

Place each emitter where water can enter soil near the root zone. Keep the outlet visible enough for seasonal checks.

A 30-pack supports route refreshes

The 30-pack format fits setup work and refill needs. It can support several patio pots, a row of vegetables, a shrub line, or a greenhouse bench.

Keep plugs, stakes, a punch tool, and an emitter tool nearby. Those pieces help with changes when a water point moves or a line needs cleanup.
