The Whale 12mm Surge Damper WS7205 is designed to reduce water pump pulsations and noise in caravan, motorhome and marine water systems, helping deliver smoother water flow while protecting pressure switches in pressurised installations.
Designed to improve the performance of onboard freshwater systems, this genuine Whale accessory helps minimise the pressure fluctuations that can occur when an electric water pump operates. These fluctuations can cause uneven water delivery, noticeable pump cycling and unwanted noise throughout the vehicle’s plumbing.
The surge-damping design helps absorb pressure variations within the water system, providing a more consistent supply to taps and showers. This makes it particularly useful in caravans and motorhomes where smooth water delivery is important for everyday washing, cleaning and showering.
One of its main advantages is its ability to reduce water pump pulsation. In some pressurised systems, pumps can rapidly cycle on and off as pressure changes. The Whale Surge Damper helps smooth these variations, reducing the noticeable surging that can occur when water is drawn from the system.
The damper also helps minimise noise associated with pump operation. By reducing pressure fluctuations within the pipework, it can help make the water system quieter and more comfortable to use, particularly during early mornings or evenings at the campsite.
Another important benefit is pressure switch protection. In pressurised water systems, repeated fluctuations can place additional demands on the pump’s pressure switch. The WS7205 helps smooth these changes, supporting more consistent switch operation and reducing unnecessary cycling.
The damper is compatible with Whale Quick Connect 12mm plumbing systems and suitable flexible pipework, making it a practical addition to compatible caravan and motorhome water installations.
Its compact design measures approximately 215mm long and 51.5mm wide, allowing it to be installed in suitable plumbing compartments where space may be restricted.
For convenient fitting, the Whale WS7205 is supplied with mounting clips and is designed to be installed vertically. This provides a straightforward installation arrangement when incorporated into correctly configured pipework.
With a maximum operating pressure of 4 bar, the surge damper is suitable for compatible pressurised freshwater systems operating within its specified limits.
Whether you are upgrading an existing caravan water system, addressing pump pulsation or replacing a worn surge damper, the Whale WS7205 provides a practical solution for smoother water delivery.
