Raindrip Adjustable Eight-Outlet Bubbler

Convert a Sprinkler Riser Into an Eight-Zone Drip Watering Point

Watering multiple containers off a single sprinkler riser usually means either running a full drip manifold or hand-watering one pot at a time, and neither option scales well past a handful of plants. The Raindrip Adjustable Eight-Outlet Bubbler threads directly onto a 1/2 inch MPT sprinkler riser through its 1/2 inch FPT inlet and splits that single water source into eight independently adjustable outlets, each with a swivel arm for positioning 1/4 inch supply tubing.

Each of the eight outlets adjusts individually from 0 to 30 GPH, so growers can dial in more flow to larger containers and less to smaller ones off the same riser. The body is molded from ABS plastic treated with UV inhibitors for outdoor durability.

Key Features & Benefits

• 1/2 inch FPT inlet — threads directly onto a standard 1/2 inch MPT sprinkler riser
• Eight independently adjustable outlets — each adjusts from 0 to 30 GPH to match flow to individual containers
• Swivel arm per outlet — positions 1/4 inch supply tubing toward each plant
• UV-treated ABS plastic body — resists degradation from sustained outdoor sun exposure
• Riser-mounted design — converts one sprinkler zone into eight individual drip watering points without re-plumbing the zone

Who Should Use This Bubbler

Growers who want to convert an existing sprinkler riser into a low-flow drip system watering up to eight individual containers, without adding a separate drip zone or manifold, will benefit from this bubbler.

Frequently Asked Questions

How many plants can this bubbler water?

It has eight individually adjustable outlets, so it can water up to eight containers from a single sprinkler riser. Each outlet's flow is set independently of the others.

How do I install this bubbler?

Thread the bubbler's 1/2 inch FPT inlet onto an existing 1/2 inch MPT sprinkler riser. Then run 1/4 inch supply tubing from each of the eight outlets to an individual container, using the swivel arm on each outlet to aim the tubing.

What is the flow rate per outlet?

Each of the eight outlets adjusts independently from 0 to 30 GPH. This lets growers set a higher flow for larger containers and a lower flow for smaller ones on the same bubbler.

Is this bubbler pressure compensating?

No, this is a non-pressure-compensating emitter, so actual flow will vary somewhat with tubing length and elevation changes between outlets. A pressure regulator upstream of the riser is recommended to keep flow consistent.

What is the bubbler made of?

It's molded from ABS plastic treated with UV inhibitors. That construction is intended to hold up to sustained outdoor sun exposure without becoming brittle.
