WaterBoost ATX-80 House Mains Pressure Booster

The WaterBoost ATX-80 is the compact tier in the ATX integrated accumulator booster range, connecting directly to the incoming cold water mains. It combines an 80-litre sealed accumulator vessel with a variable speed pump in a single compact unit — automatically boosting both pressure and flow throughout the property the moment a tap or shower is opened. No break tank, no overflow arrangement, just two water connections required. The system delivers a sustained boosted flow of 16 l/min at 3.2 bar for up to 11 minutes — before settling to a continuous boosted flow of 12 l/min at 3 bar until the vessel recharges. The 80-litre vessel provides 48 litres of useable working capacity. Variable speed inverter technology means the pump only generates the pressure your mains can’t already deliver, keeping running costs to a genuine minimum. Operation is measured at a quiet 40 dB(A). WiFi via the DConnect app enables remote monitoring and control. A mains bypass fits in seconds using 2 clips if the unit ever requires attention. WRAS approved product. Fully sealed system — zero air contact with stored water, no hygiene management required. Completely maintenance free. Suited to 1-bathroom homes, smaller properties with poor mains pressure, combi-boiler installations and unvented cylinder systems. 5-year tank warranty, 3-year pump warranty.
