The pump worked very well throughout last summer. Unfortunately, despite the maintenance instructions, the O-rings at the hose connections have dried out and are unusable. I can't find the dimensions in the instructions for replacing them.
Unfortunately, the pump is not leak-proof when not running and, according to the seller, the pool has to be disconnected every time the pump is not running. That can't be right, so I wouldn't buy this product again. It's better to go for a better pump, e.g. from Intex, which can be connected to a timer.
