JR Race Car 03054 Blow-Out Plug for RV Water Line Winterization

The JR Race Car 03054 blow-out plug is an essential winterization tool designed to help you safely pressurize and evacuate water from your RV or trailer plumbing system. This simple yet effective plug connects to your city water inlet, allowing you to introduce compressed air into your water lines to clear them of residual water before freezing temperatures arrive.

Key Features:

• Holds air pressure securely until manually removed from the water inlet
• Allows controlled pressure release by opening faucets throughout the system
• Prevents damage to your water fill check valve by using faucets for pressure relief
• Durable construction designed for repeated seasonal use
• Compatible with standard RV city water connections

To use, simply connect the blow-out plug to your city water inlet, attach an air compressor (regulated to 30-50 PSI maximum), and open faucets one at a time to evacuate water from your plumbing system. This helps prevent costly freeze damage during storage and ensures your water system is properly winterized.
