Product Overview

This Truma Ultrastore Safety Drain Valve 2.8 Bar 12 mm is the official Truma over‑pressure and drain valve used on Ultrastore water heaters in caravans and motorhomes. It protects the boiler by opening at around 2.8 bar to relieve excess pressure and also serves as the manual drain point for winterising or servicing, usually via a yellow lever and an outlet pipe through the floor. With 12 mm connections for common caravan plumbing systems and rated for up to 4.5 bar system pressure, Truma part 70141-02 is the correct OEM replacement when the original safety/drain valve is leaking, blocked or no longer operating correctly.
