The newer Jacuzzi (בריכות ספא) are also fitted with jets or spouts at various levels along the inside of the tub. These jets release pressurized water which has been known to be quite soothing. These can be fitted inside your home or in the yard, depending on the availability of room. They are usually quite easy to install and maintain and are generally enjoyed by people of various age groups.
The hazards are real and, in many cases, can become very serious too. It is owing to the health reasons that it is imperative that the tub be cleaned and disinfected regularly. The warm water becomes a breeding ground for various bacteria since bacteria thrive in warm, damp areas. There are also a wide variety of fungi which can thrive around Jacuzzis. Recreational Water Illnesses or RWIs can spread quite fast around these tubs and because a large number of people may be using the tub at about the same time, most of them could be inflicted. The illnesses that one can catch can vary from skin diseases like rashes and boils to diarrhea l illnesses as well as respiratory problems as well. It is therefore important for Jacuzzi water treatment (ג׳קוזי לחצר) to occur on a regular basis so that the water and the tub is kept clean and disinfected.
Another important reason to clean the tubs is for the sake of maintenance. The tubs usually have a water filter that needs to be cleaned from time to time. If this is not done, the trappings which include dirt, dust, leaves, other plant material, hair, etc. could block the filter completely. Other than that, mineral residue from the water may start coating the insides of the jets causing the water to lose some of its pressure.
