    There’s a combination of flaws. The strainer basket doesn’t do a very good job keeping debris out of the impeller. There’s little separation between the steainer and the impeller. So long hairs that are partially caught in the strainer can still wrap around the impeller.

    The pump itself has a terrible impeller design. The impeller is nylon and is press fit onto a 1/8 brass rod that just has a flat ground on it, no knurling or splines. The nylon cracks easily and ends up free spinning.

    They use the same pump in loads of washer models. So yes, there’s a very large user base, but that’s a lot of people with part failures. The pump is garbage and lg should not be using it.














  • The speed of sound in seawater is around 1500m/s or 5400 km/hr. Something tells me they won’t actually be going supersonic.

    The article shouldn’t be referencing the speed of sound without specifying the medium for the sound waves and conditions such as temperature for water or temperature and pressure for air.

    Also, the supercavitation would be incredibly noisy underwater, and at those speeds the vessel itself would produce a very loud pressure wave that would be easy to detect. So its advantage wouldn’t be in avoiding detection, it would be in moving fast enough that detection doesn’t matter because no torpedo could intercept them.
