NOT submersible - it is IP44 which is spashproof. Apart from that, which they promised to remove, it is fine. I am using it to pump water around 400 feet of 13mm irrigation hose in a solar heating system. There are many loops and ups and downs and it's capable of pushing water around at a reasonable rate. It does need to be primed but I just use a hose from the mains and then dip the inlet under the water in the outdoor pool I am heating once it starts to flow.
