Review: Ideal product for hot tub water removal - Fantastic product. It does a great job, and at a very fast rate of water removal from my hot tub.
Review: Great product, but needs 10 cm minumum water depth to start pumping - There are several almost identical pumps for sale on desertcart at various prices. I went for the one from AIMTools, because this firm offered free post and packing. The dearest one on desertcart is almost twice the price, and is probably no better. I had initial difficulty connecting a hose because I had not thought to order a suitable one with the pump. However, after sorting this out, the pump easily drained the inspection pit in my garage, which had accumulated half a metre depth of ground water, taking about 30 minutes to do so. The only negative point, which is probably shared with all the other similar pumps for sale on desertcart, is that the pump stops sucking when there is still 5 cm of water depth remaining, even if the float switch is held up with a piece of string. Also, it won't start sucking again unless there is at least 10 cm of water depth. This seems to be due to the design of the impeller and the cavity above it. The pit to be drained really needs to have a sump at a low point in the pit to accommodate the pump. I still gave the product 5 stars, because at the price, it is excellent value if you can accept the limitation.
