Hi,
we have a Grundfos STC-1.5c twin impeller pump installed. Sometimes it will work and then not at all. It won't turn on and there is no water flow at all. If it does work, it works fine, doesn't cut out or waterflow isn't reduced, no issues at all. But if another person would want to take a shower e.g. it won't even turn on at all. Sometimes not for a few days.
Has anyone experienced this and what could be the issue? The pump itself seems to be working fine, just does so whenever it feels like it
