Toro 533 Adjustable Flood Bubbler 1.36-5.9 Gpm

Product Description

The TORO 533 is an adjustable flood bubbler designed for low-volume irrigation applications. It delivers a controlled flood pattern across a defined area, making it well-suited for watering shrubs, ground cover, and densely planted beds where overhead spray is not ideal. The flow rate is field-adjustable between 1.36 and 5.9 gallons per minute (GPM), allowing the installer to match output to the water demand of a specific zone without swapping components. Landscape irrigation professionals and irrigation system installers are the primary trades that specify and install this bubbler.

The 533 is used in residential and light commercial landscape irrigation systems where flood or basin watering is the preferred distribution method. It is typically installed at grade level or slightly above in shrub beds, tree rings, and planter areas. The adjustable flow range makes it practical across a variety of soil infiltration rates and plant water requirements. It fits into drip and low-volume irrigation zones where precise, localized water delivery reduces runoff and overspray.

Key Features

• Field-adjustable flow rate from 1.36 to 5.9 GPM for flexible zone design
• Flood pattern distribution suited for shrub beds, tree basins, and ground cover areas
• Low-volume output reduces runoff compared to standard spray heads
• Compact bubbler format for installation in tight planting areas

Compatibility

Designed as an OEM-style replacement or new-installation bubbler for residential and light commercial low-volume drip and flood irrigation systems.

Installation Notes

Installation is typically performed by a licensed irrigation contractor or landscape professional. Shut off the irrigation system water supply and relieve line pressure before making any connections. Follow local plumbing and irrigation codes for backflow prevention requirements when installing low-volume emitters. Adjust the flow rate after system pressurization using the manufacturer-provided adjustment mechanism to achieve the target GPM for the zone.
