Very good work is done, it has absolute waterproofing. The only thing I don't know is if over time the material will corrode because I will have the joint inside the water of the well. If it is outside the water and just gets wet without being hit by the sun, I don't think it has an issue for decades. For more safety, I also put elastic insulating tape on the outside. Generally very satisfied and easy in the process with the resin, although I had flat cable on the pump side as shown, it is the blue one in the photo
