WaterBoost AWB-300LV — 300 Litre Vertical Accumulator Vessel

The WaterBoost AWB-300LV is a 300-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-300LV operates on a 60% usable volume ratio — delivering approximately 180 litres of high-pressure water before returning to normal mains flow. At a typical shower flow of 12 l/min, 180L supports two simultaneous showers for approximately 7.5 minutes before returning to normal mains flow. Diaphragm design, WRAS-approved construction, maintenance free. The AWB-300LV is suited to 2–3 bedroom homes and larger properties with higher simultaneous demand.

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.
