Coast RV Caravan Pressure Accumulator Tank | Water Pump Surge Vessel

$89.00

The Coast RV Caravan Pressure Accumulator Tank is an essential plumbing accessory that dramatically reduces water pump cycling, extends pump motor life, and eliminates the pulsing water flow often experienced with diaphragm pumps in caravans and motorhomes. By maintaining a pressurised air cushion, the accumulator absorbs pressure spikes and smooths out water delivery — so your tap runs evenly and quietly, even at low flow settings.

Easy to install inline on any 12mm or 19mm plumbing system, the accumulator tank connects between the pump outlet and the first T-junction or tap in your water circuit. It is particularly effective when paired with a high-flow pump such as the Coast RV 200-20728, and is beneficial in any caravan plumbing system that uses a pressure-switching diaphragm pump. Suitable for all standard caravan, motorhome, and boat water systems.
