Accumulator Tanks for Campervan Water Systems

An accumulator tank (also called a pressure vessel or expansion tank) sits between your water pump and your taps. It stores water under pressure and releases it when you open a tap, reducing pump cycling.

Why You Need One

Without an accumulator: every time you open a tap, the pump switches on immediately. Every time you close it, the pump switches off. The pump cycles on and off hundreds of times per day. With an accumulator: the pump fills the accumulator tank, then switches off. When you open a tap, pressure from the accumulator pushes water out. The pump only switches on when the accumulator pressure drops below a threshold.

Benefits

• Pump runs less = longer pump life (pumps fail from cycling, not running)
• Smooth water flow (no pulsing from the pump)
• Quiet operation (pump runs less frequently)
• Water available for 5-10 seconds even if pump fails

Installation

1. Install the accumulator after the pump, before the first tap
2. Use a T-piece to connect the accumulator to the cold water line
3. Pre-charge the accumulator to 1-2 PSI below the pump's cut-in pressure (typically 20-25 PSI)
4. Secure the accumulator to the van floor (it can vibrate)

Products

Conclusion

An accumulator tank costs £15-25 and takes 10 minutes to install. It dramatically improves water flow and extends pump life. Install one.
