The ONA System
In this video, we walk through the full ONA extraction process for Delta cartridges from start to finish:
- Shutting off water and removing the nut
- Installing the ONA Tube for Delta (999150-7)
- Using the ONA Puller and crank to remove the cartridge
- Assembling the claw (two-rib + one-rib pieces) to grip and remove a broken balancing spool
- Using threaded rod, tube, and crank to push against the valve body and pull the spool free.
