WaterBoost AWB-200LV — 200 Litre Vertical Accumulator Vessel

The WaterBoost AWB-200LV is a 200-litre WRAS-approved vertical accumulator vessel for mains-connected water systems. Accumulators store mains water under pressure — so when you open a tap or shower, you draw instantly from the vessel at full mains pressure rather than waiting for the mains to respond. The result is a noticeably stronger, more consistent flow from every outlet, even during peak demand.

The AWB-200LV operates on a 60% usable volume ratio — delivering approximately 120 litres of high-pressure water before returning to normal mains flow. At a typical shower flow of 12 l/min, 120L supports one shower for approximately 10 minutes, or two simultaneous showers for approximately 5 minutes before returning to normal mains flow. Diaphragm design, WRAS-approved construction, maintenance free. The AWB-200LV is suited to 1–2 bedroom homes.

Requires a minimum 2 bar static mains pressure to operate effectively. If your static pressure is below 2 bar, add the WaterBoost ACF1 accumulator booster pump to charge the vessel to the required working pressure.
