The pump is quickly and well packaged with me angekommen.Habe they also installed immediately, runs and promotes to my satisfaction even enough water, especially the pressure in my stash boiler is readily gehalten.Bin very pleased with the submersible pump! 4 stars only because I requested a German description of the pump at the company, but have not even found it necessary to leave it to me to get a Nacricht until today. The original version of the documentation is only in Russian, I can not read and translate can not.
