Tundish Open - 28mm x 22mm Compression
This straightforward plastic tundish is an essential component for unvented hot water and heating systems. Designed to act as a visual monitoring point, it allows you to safely observe water discharge from pressure relief valves, ensuring your system operates correctly and complies with UK building regulations.
What It Does:
- Leak Detection: Provides a clear view of any water released by safety valves (e.g., temperature/pressure relief valves), alerting you to potential system issues.
- Prevents Cross-Contamination: Keeps discharged water separate from the main system, maintaining hygiene in potable water setups.
- Regulatory Compliance: Required in unvented systems to safely direct overflow water and meet UK safety standards.
- Durable Plastic Construction: Lightweight, corrosion-resistant, and built for long-term use.
- 28mm Inlet x 22mm Outlet: Compatible with standard pipework in domestic heating and hot water systems.
- Simple Installation: Fits vertically in discharge pipework, often near unvented cylinders or combination boilers.
- Homeowners and installers needing a cost-effective, regulatory-compliant tundish.
- Basic monitoring of pressure relief valves in small-scale domestic systems.
