Essential valve protecting water systems from over-pressure and backflow

A combination pressure relief and non-return valve designed to safeguard hot water systems by releasing excess pressure and preventing reverse flow. This dual-function component helps protect internal plumbing and heater tanks from damage, making it ideal for compact RV, caravan, and marine systems that require reliable pressure control and one-way flow protection.

Key Features

• Pressure relief protection: Automatically releases built-up pressure inside the hot water system to prevent stress or damage to pipes and tank components
• Non-return (one-way) flow: Prevents water from flowing in reverse toward the supply, reducing the risk of backflow and maintaining correct directional flow.
• Combined safety functions: Integrates two critical safety mechanisms in one compact valve, simplifying installation and reducing the number of separate fittings needed.
• Suitable for compact systems: Designed for smaller hot water tanks (typically under 50 L), commonly found in mobile and off-grid applications.
• Standard ½″ fittings: Fits common inlet and outlet pipe sizes for ease of replacement or upgrade.
• Durable brass construction: Provides long-lasting performance in various environments including RV, caravan, and marine setups.

This combination valve is ideal for maintaining consistent water flow and protecting against pressure-related failures in mobile and compact hot water systems.
