For the past 12 months, I have been using the injection method to dry out the walls in this basement. For support I have built a pump shaft, a pump sump. In it is a submersible pump with an integrated float switch. The pump reliably pumps out the water.
After a month, the pump no longer switches off automatically. It rattles strongly and makes loud noises.
Small stones have come loose from the substrate and have been sucked in by the pump. This has caused a lot of damage.
How I repair the pump again and additionally install a check valve, I show in this video.
