Horizontal Accumulators – Solutions for Low Water Flow Applications
Water pressure and flow can fluctuate, especially during peak usage times such as mornings and evenings, leading to reduced mains pressure. Accumulators address this issue by storing water under static or resting pressure, ensuring a more consistent supply.
Even if mains pressure is sufficient, the design and condition of the plumbing—particularly the pipes connecting your home to the mains—can significantly reduce both pressure and flow by the time the water reaches your taps. Accumulators help mitigate these challenges, delivering reliable water performance.
Designed for optimal performance and durability, these maintenance-free, WRAS-approved vessels provide a reliable solution for water pressure and flow management.

Frequently Asked Questions
Quick answers to common questions about the WaterBoost 150 litre accumulator Horizontal. For technical specifications, see the product details above; for sizing or installation advice, contact our team. If you have any other questions, we're happy to help.
What is an accumulator tank?
An accumulator tank is a pressurised vessel that connects directly to the mains supply and stores water under pressure. When a tap or shower opens, water discharges immediately from the vessel at full mains pressure rather than drawing only from the street main. This delivers stronger, more consistent flow at peak times. Accumulators have no pump and no moving parts so they are maintenance free and silent.
When should I use an accumulator instead of a pump?
An accumulator is the right solution when static mains pressure is adequate – above 2 bar – but flow is poor or drops during peak demand. It boosts available flow without adding a pump, energy use or noise. If static pressure is below 2 bar, a booster pump is needed instead, or an accumulator combined with a charge pump such as the WaterBoost ACF1.
What size accumulator do I need?
Accumulators are typically sized on a 60 per cent usable rule – a 300 litre vessel delivers around 180 litres of boosted water per cycle. As a guide, a 2 to 3 bedroom home suits a 300 litre vessel such as the GWS GCB-300LV. Larger 4 to 5 bedroom homes or properties with multiple bathrooms typically need 450 to 600 litres. Vertical models save floor space, horizontal models suit lofts and roof spaces.
