Overview

The NOVINO RV Vacuum Breaker Check Valve offers a targeted upgrade for your black tank flush setup. It serves as a replacement for cracked or leaking valves, helping to reduce damp spots on the floor and maintain steady operation during tank flushes. Designed for simple integration, this valve is a practical addition for RV maintenance.

Installed between the freshwater inlet and the tank flusher, it acts as an anti-siphon barrier to prevent backflow. By preserving the integrity of the clean water line, it supports reliable flushing performance and a quieter, more controlled flush experience.

Key benefits

  • Backflow prevention helps protect the freshwater supply from siphon risk during tank flushes.
  • Simple replacement option for aging or leaking valves, restoring system reliability.
  • Designed for standard 1/2" NPT connections on both ends, facilitating compatibility with common RV plumbing.
  • Part of a black tank flushing system that works with typical RV setups to support routine maintenance.

Fit, specs & what to expect

  • Operating pressure range: 8–125 PSI, ensuring compatibility with most RV water systems.
  • Connection type: 1/2" NPT male threads on inlet and outlet for straightforward installation.
  • Placement: between the freshwater inlet and the tank flusher to maintain a clean, ready-to-use circuit.
  • Maintenance note: replace a leaking valve to restore flushing performance and reduce incidental spills.

While this valve is designed to support a robust RV water system, actual results can vary with system configuration and use. Consider it a dependable enhancement that may help improve consistency and protect your water source during black tank flushes.
