Raindrip Inc R158CT Full Circle Stream Spray Bubbler

Product Description

The RAINDRIP INC R158CT is a full circle adjustable stream spray bubbler designed to convert existing half-inch underground sprinkler systems to low-flow watering in areas where a dedicated drip circuit cannot be installed. The R158CT delivers a maximum spray diameter of 3 feet and is rated for operation up to 30 psi. It threads directly onto a standard 10-32 NFT threaded inlet, making it a straightforward swap for licensed irrigation technicians and experienced installers working on residential or light commercial irrigation retrofits. The package includes 10 units, each sold as an individual piece of measure.

This bubbler is suited for landscape beds, planters, and tight planting areas where full sprinkler coverage is impractical and a drip irrigation circuit is not feasible. It fits into existing half-inch underground sprinkler system risers, allowing technicians to retrofit zones for low-flow watering without reworking the supply piping. The adjustable stream pattern allows output to be dialed in at the head, reducing runoff and improving water distribution in targeted zones.

Key Features

Compatibility

Installation Notes

Installation should be performed by a qualified irrigation technician or licensed contractor. Shut off the irrigation zone and relieve system pressure before removing the existing sprinkler head or riser. Thread the R158CT onto the 10-32 NFT riser fitting hand-tight, then verify for leaks at startup. Adjust the stream output at the head to achieve the desired spray pattern before finalizing the installation.
