John Guest - 12mm Single Check Valve

The John Guest 12mm Single Check Valve is a small but crucial component for your campervan's plumbing system.

Prevents Backflow

This valve allows water to flow in one direction only, preventing unwanted backflow or siphoning within your plumbing system. This is essential to avoid contamination and ensure proper water flow throughout your campervan.

Protects Against Siphoning

In situations where the water pump is off or the water pressure drops, a single check valve prevents contaminated water from being siphoned back into your freshwater supply. This helps maintain clean and safe drinking water.
