Pros and cons

Pros

Automatic shut-off and restart are useful where the water level may fall and later be restored.
Three hose fitting sizes give options for connecting to different feature hoses.
The listing provides flow figures at several outlet heights, helping estimate performance for a planned fountain.

Cons

Flow falls substantially as the outlet is raised, so the maximum-flow figure does not describe performance at height.

What to know before buying

Listing details to confirm

The listing gives differing dimensions: product details state 13L x 9W x 7H centimetres, while the feature text states 14cm long, 8.5cm wide and 9cm high. It also describes maximum height as 1.7 metres in the title and details, but gives 150 cm in feature text. Flow is listed as 1100 litres per hour in details and the flow chart, while feature text says 1200 litres per hour. The chart states 292 litres per hour at 150 cm, so check the required outlet height and dimensions against the selected listing before purchase. The pump should be placed on a firm, level base in the pond or feature.

Customer feedback reports positive impressions of build quality, flow and value, while reliability experiences are mixed. Some customers describe the pump as reliable, while others report it stopped working after two months. For a water feature, the reported flow appreciation is relevant, but the flow chart shows output falls with lift, and the differing reliability experiences are worth weighing for continuous use.

Positive themes

Customers describe it as good value for money.

Mixed feedback

Reliability feedback is mixed, with some customers describing reliable operation and others reporting failure after two months.
