Accumulator Tank

📝 Accumulator Tank – Pressure Stabilising Water System Upgrade

The Accumulator Tank is a bladder-type pressure storage vessel designed to smooth out your water system, reduce pump cycling, and eliminate pulsation. By holding water under pressure, it improves flow consistency, reduces pump noise, minimises amperage draw, and extends pump life. Featuring two screw mounting points with rubber grommets, it delivers excellent vibration resistance for a quieter, more efficient setup.

⭐ Essential Benefits

• Smoother water flow – reduces pulsation for consistent pressure at the tap.
• Longer pump life – minimises rapid cycling and wear on the pump.
• Lower amperage draw – improves overall system efficiency.
• Noise reduction – dampens vibration and pump hammering sounds.
• Simple installation – compact design fits easily into carava n and camper plumbing layouts.

⚙️ How It Works

The accumulator uses an internal bladder that stores water under pressure. As you open a tap, water is released from the tank before the pump activates, reducing on/off cycling and stabilising flow. Before installation, the bladder’s pre-charge pressure is set slightly below your water pump’s output pressure to ensure proper performance.

🔌 Compatibility

• Suitable for 12v caravan, campervan, RV, and marine water systems
• Works with diaphragm-style water pumps
• 1/2" BSP female fittings for simple inline connection
• Ideal for both new installations and upgrades to existing plumbing

🧰 Installation Difficulty

🟢 Easy (2/5)
Mount using the two anti-vibration screw points, adjust pre-charge pressure, and connect using standard 1/2" BSP fittings.

🔍 Features

• Bladder-type storage – maintains stable pressure and smooth output.
• Anti-vibration mounts – rubber grommets reduce noise transmission.
• High working pressure – rated up to 125 psi (8.6 bar).
• Compact size – easy to position in tight service spaces.
