Leaking 3

Hello,
I bought this pump despite negative reviews.
But regret is probably the wrong word, the other products did not have better reviews.
Among the negative points:
Instructions under all, especially in terms of images. In the pictures can not be seen where get there which tubing or seals.

The connectors also do not fit exactly, and had to get some reasonably sealing only by means of clamps.
While I spent a week on holiday the clamping ring sparked außenrum light and me disappeared 20cm of water in the pool ....
Apart from the tension ring is not dichtzukriegen 100%, here tropfts still occasionally out.

Otherwise, the pump is nice, it does what it should. Nevertheless, I have now even the sporadic form, the problem is algae on the floor because Helps also run 6h / day nothing.
