The WaterBoost WB-Compact 3.0 is a compact variable speed inline mains pressure booster that connects directly to the incoming mains supply — no tank, no break tank, no overflow. It reacts automatically to low mains pressure, boosting supply to the entire property to up to 3.0 bar at up to 12 l/min. Ideal for combi-boiler homes, unvented cylinders, electric showers, and mixer showers.
The variable speed inverter motor adjusts output to match demand, delivering smooth and stable pressure at a measured 40 dB(A) — quieter than a normal conversation. Built-in WiFi connects to the DConnect app for remote monitoring and control, and supports voice commands via Google Home and Amazon Alexa. Available in straight ¾" BSP and right-angle ¾" BSP connections. A full-bore bypass can be fitted for uninterrupted supply during maintenance.
WRAS compliant. 3-year warranty. For higher maximum pressure, see the WB-Compact 4.5. For a storage-based solution, see the ATX-200.
