Patented scoops and water vanes recirculate both vessels continuously, so the water in your home stays as fresh as the day it arrived. No break tank, no overflow, just two water connections required.\u003c\/p\u003e\n\u003cp style=\"margin: 0 0 14px 0;\"\u003ePeak burst flow reaches up to \u003cstrong\u003e140 l\/min\u003c\/strong\u003e, with \u003cstrong\u003e60 l\/min sustained for up to 11 minutes\u003c\/strong\u003e — before settling to a continuous boosted flow until the vessels recharge. The twin-vessel arrangement provides \u003cstrong\u003e540 litres of useable working capacity\u003c\/strong\u003e — double the single ATX-450 Pure. Variable speed inverter technology means the pump only generates the pressure your mains can’t already deliver, at a quiet \u003cstrong\u003e40 dB(A)\u003c\/strong\u003e. WiFi via the \u003cstrong\u003eH2D App\u003c\/strong\u003e enables remote monitoring and control.
