The white material comes from the home & garden machine. Heating the water in the pump can cause the so-called pressure compensator to dissolve.
We usually observe that the cause of this behavior is triggered by a fault in the installation.
In this case, the home & garden machine switches on again and again without water being drawn off. This behavior leads to a strong heating of the water in the pump, which in turn can damage/dissolve the pressure compensator.
Make sure that the installation is tight on the pressure side, especially all tapping points. You should also check the non-return valve of the home & garden pump. To be able to check the pump, we recommend that you send it in for inspection.
