Review on Well pump DAB DIVERTRON 1000 M (650 W) by Boyan Zlatev ᠌

I installed it in a well 5 m deep with wiring to the bathhouse and the house about 30 meters to each and forgot about it. Everyone writes that it is sensitive to voltage drops, my voltage constantly jumps like that, but there are no problems. An excellent pump and protection against dry running, there is also a check valve. In winter, I use it periodically and don’t get it out of the well, there’s no drain valve and nothing freezes. This year, the temperature reached -30 at night and at least that.
