Some cheap Jacuzzi (ג’קוזי) which are usually cheap imports from the East claim to have many Jets but many times there are just simple pin point Jets, which do not rotate, or cross fire and are un-adjustable and in my view not really worth having but can look very enticing to a prospective purchaser. These Jets can be very intense and as they are not adjustable they can actually be painful. You want the very latest in design whereby the Jets provide a vigorous massage to loosen those tight knotted muscles and at the same time increase the blood and oxygen circulation which helps to bring nutrients to sore muscles and joints.
It is very amusing when you get some so called Jacuzzi specialists talking about the number of jets in a spa pool without having even taken into account the strength of the pumps which are going to power those very Jets..
So these many jets simply do not have enough power to actually make these Jets perform properly, So for performance in a Jacuzzi (ג’קוזי) it is just not a simple question of the number of Jets but it does come down to things like engineering and design and the balance of the Jets with the correct motors and water pumps to produce the better all round product More often than not, these Jacuzzi with lower rated motors have to have a diverter valve fitted so that other parts of the spa can be turned off to get any decent power where one is actually sitting.
Usually the maker of Jacuzzi (ג’קוזי) here is clearly out to save some money on his production costs or perhaps it is a cheap eastern import. The manufacturer will use a standard or probably a mould from production hence the too many jets and to save money simply fits underpowered motors to drive the pumps. Some times these are sold as unbranded products as the maker does not want to put his name to them, as he well knows that they are a much cheaper line.
