This video will be useful if you (like me) have a submersible borehole pump that does not start the first time or does not start at all. My pump is a Vikhr SN-90A (SN-90V), but in fact, everything that happens in this video will be true for most screw (auger) pumps. If your pump starts but does not pump water well, then this video is not for you. You just need to replace the screw and rubber casing. Before disassembling the pump, make sure that your mains voltage is normal. Pumps often do not start due to low voltage. And check that the pump is not simply clogged. If everything is normal, then you can safely repeat after me :) 00:00 Who is this video for 00:51 DISASSEMBLY OF THE PUMP 05:01 Inspection of the capacitor 07:40 Characteristics of the capacitor and a little theory 08:25 Checking the capacitor 11:10 INSTALLING A NEW CAPACITOR 19:00 REASSEMBLY OF THE PUMP 23:14 Why I recorded this video 24:01 If the pump does not pump well 24:45 Starting the pump 25:18 Lowering the pump into the well Playlist about this house - • AERATED CONCRETE (extended version) My social networks: YouTube - / @good_home Vkontakte - https://vk.com/good_h0me RuTube - https://rutube.ru/channel/15452475/ GoodGame - https://goodgame.ru/channel/GoodHome Odnoklassniki - https://ok.ru/group/70000003387428 Pikabu - https://pikabu.ru/@v.pdk Yandex.Zen - https://zen.yandex.ru/good_h0me Telegram - https://t.me/good_h0me #GoodHome #WhirlwindSN90 #PumpRepair
