Good and inexpensive filter system with slight weaknesses

The filter system is quick to install and works reliably. The noise level of the pump is low. In a small enclosure made of wood it is barely audible. The switch to the integrated timer allows switching on and off of the pump without before switching on 7-way valve always having to pull the plug. Unfortunately, I had to switch off the installation repair once, for some reason - probably due to the transport - the switch was deformed and disabled. Through a spirited push back the damage could be repaired.
The accompanying description has formulated a little bulky.
When installing, it is difficult to get all the screw tight - especially licking the two sight glasses and need to be very tightly closed. Filter cover container and filter are connected by means of a clamping ring. To get here close the system is nearly impossible. In operation it drips even after repeated re-tensioning of the ring.
I have the filter for a bath tub of almost 2m² in use - this is the circulation rate over ausreichend.Das filter result is very satisfactory.
