TNITRIB Rain Sensor Hygroscopic Discs Replacement for Hunter & Rain Bird Sensors | 8-Disc Pack

Restore your rain sensor in minutes with TNITRIB

Over time, the wicking pan inside a rain sensor can wear, leading to inconsistent readings and uncertain sprinkler coverage. Instead of replacing the entire unit, you can refresh the sensing action by swapping in fresh hygroscopic discs. The TNITRIB replacement set includes eight small discs that soak up moisture and help the cap breathe again, helping your system respond as intended.

Designed for compatibility and ease, these discs are engineered to work with all Rain Bird Rain Sensors—RSD and WR2 Wireless—and are also suitable for Hunter models like Mini-Clik, Rain-Clik, and Solar Sync. The swap is quick, clean, and simple, so you can get back to yard care without a long repair cycle.

Real-world use cases and benefits

Think of a dry season where a sensor seems erratic, or a sensor that stops reading correctly after a weather shift. With this disc pack, you have a straightforward way to refresh the sensing surface. It’s ideal for homeowners who manage multiple zones, landscapers keeping installations in good shape, or anyone who prefers cost-effective maintenance over full replacement.

• Restore consistent sensor behavior without a service visit
• Extend the life of existing rain sensors
• Keep sprinklers on schedule with refreshed moisture sensing

Installation tips

Open the sensor cap, remove the worn discs, and replace with the eight new discs. This setup requires no tools, and you’ll likely hear a quiet click as the cap seats. For best results, reassemble and test the sensor before returning to normal irrigation.
