Before buying, I read the reviews but didn’t look in which cities these people live, but in vain, in Hong Kong the pressure is such that the pipes are buzzing well, and in other large cities, probably too, but we have a maximum of 1-1.5 atmospheres, although at first glance it seemed that everything should work, in general, if you decide to buy, then be prepared to buy a special pump for it for 5000. well, or immediately buy for 11,000 with a pump.See full review
