Due to the very different reviews, I was not sure if this filter system is any good. Luckily, there are Amazon with its famous peaks service! So buy conditioning ... and do not get close to the start! The problem is simply that the sand container is under increased pressure (actually just 0,7bar). The pump pushes the water up in and through the sand filter. The black Plastering the sand container to the pressure withstand, but does not particularly stable impression. And so it has gradually let him rip!
Solution: Amazon - exchanged> Plastering and broken ring (complete system) back -> brought 4 clamps at the hardware store and distributed around the Plastering -> now holds it tight!
The timer can forget it, because I do not want to let this system work unsupervised!
