Drip Irrigation Supplies

Choose inline dripline spacing and tubing length

Separate the length of the watering route from the spacing and flow of the outlets on it.

Mark where water is needed

Sketch the run and mark the places that need delivery. Compare emitter spacing and rated flow with that layout, then distinguish an inline emitter coil from blank tubing used to reach the first outlet.

Read the model's limits

Check the documented pressure range and run limits for the selected product and layout. Verify what fitting and closure the maker specifies. Different coil lengths of the same product can still require the same connection.

Plan the end and branch fittings

Allow space for turns, connectors and the approved end closure. If you need a flush point or an isolating valve, identify it separately when making your parts list.

Guide questions

Is blank tubing the same as inline dripline?

Blank tubing has no factory-spaced emitters.

Does a longer coil change the outlet spacing?

Confirm the exact SKU. A length variant can retain the same spacing.

Which diameter does the end closure need?

Use the compatible diameter range specified for that closure and tubing.

Which tool suits the job?

  1. The T22-100S is blank quarter-inch tubing for carrying water between selected points. The ET256-50S has outlets every six inches for an evenly spaced run. Use the length of each part of the route to decide where each type belongs.

  2. The Rain Bird ET256-50S puts .8 GPH outlets six inches apart in quarter-inch emitter tubing. The Raindrip R292DP uses 1.0 GPH outlets at eighteen-inch intervals in nominal half-inch dripline. Compare the needed spacing and fittings before selecting either coil.
