Отзыв о Sewer installation VORTEX KN-300 (300 W) от Vassil Yanakiev ᠌

The plumber said that we would constantly call him for blockages if we did not install a sewer pump, since our equipment is below the entrance to the sewer. Obediently followed all his recommendations, bought a Whirlwind KN-300, though I did not expect that it would cost 7,000s. Installed by the same technician. Showed where to clean regularly to prevent breakdowns and prolong the life of the unit. For many years now there are no problems with the toilet.
