A true pressure reducer — not a flow controller. Drops incoming water pressure down to 15 PSI (1 bar), the safe operating range for all Tropf Blumat sensors and BluSoak systems. Screws onto any standard 3/4" hose bib and outputs directly to 8mm Blumat supply tubing. Key Features + True pressure reducer — actually lowers system pressure, not just flow rate Fixed output of 15 PSI (1 bar) — the ideal operating pressure for Blumat systems Maximum input pressure of 87 PSI 3/4" female hose thread input — connects to any standard hose bib or faucet 8mm barb output — connects directly to Blumat supply tubing, no tools needed Made from ABS plastic, Austrian-engineered, designed for long-term reliability Why a True Reducer Matters + Many products sold as pressure reducers are actually flow controllers — they restrict flow but don't lower actual system pressure. Reduced flow does not equal reduced pressure. This is a genuine pressure reducer that brings any incoming supply down to a safe 15 PSI output regardless of flow. Running Blumat sensors above 15 PSI risks pushing tubing connections apart and flooding. This is the component that prevents that.
