Sought and Found: My new filter sock for the submersible pump

For a long time I have annoyed me about the otherwise excellent submersible pump sometimes small stones of grain 3-5 mm draws with the effect that this size clogged the intake ports. While the pump is required, quickly disassembled and cleaned, you have to but once remember, because the float switch allows the pump the whole time running over.
The commercially available filter socks are far too small.

The mesh bag offered here are nearly perfect for my purpose: Large, non-rotting and in perfect mesh size. The submersible pump fits into casual, connecting cables, drainage tube and float switch protrude above bluntly. The mesh bag I fixed with cable ties in the optimum height of the pump so that the bag and the pump casing fixed tightly encloses the supernatant is rolled up and also fixed.

A small number would have done it, but now applies: Small stones have no chance.
