## Questions & Answers

**Q: What is the function of the  vent in rego lv3403tr regulator?**
A: The regulator vent allows the regulator to “breathe” during normal operation. It functions as a pressure relief opening in an over-pressure situation. For safety purposes, the regulator vent needs to remain free of dirt and debris. The vent should face down so that it does not catch water.
