Izosetshenziswa i-fietless faucet ukusetshenziswa kweminyaka engaphezu kwemithathu kubangela izifo zokuphefumula?

Amagciwane anjalo angadala ama-legionnaires ahlukile’ isifo (uphawu olujwayelekile lwe-pneumonia) nezinye izifo zokuphefumula. Abaphenyi bahlaziya 3 Ompompi benziwe ngensimbi engenasici, I-Ceramic ne-Brass ekusindisweni kwayo kweLegionella ngaphakathi 3 amashumi eminyaka. Ngaphambilini, Ososayensi bacabanga ukuthi ama-wetal conduits angadala ama-molecule ukugqwala ukukhulisa ukuzalanisa kweLebionella. Lokhu kuhlola kukhombisa ukuthi ngonyaka olandelayo ukusebenzisa ompompi bensimbi engagqwali, Inani lezinhlobo ze-legionella ezivela emanzini likhuphuka ngokushesha ngenxa yokuguga kwensimbi yabo engenacala elimelana nokugqwala ebusweni besikulumbisi. Ngokuvamile, ingxenye eyodwa kwezimpondo zensimbi engagqwali izodonsa i-legionella (Isilinganiso esiningi esivela eNetherlands), Yize ikota elilodwa le-ceramic kanye ne-brass ampompi lizohlasela uLegionella, kanye nokusetshenziswa kwepulasitiki noma yensimbi ngokuyisisekelo akukuthobi imiphumela yokuhlola. Ukwengeza, Ukuhlaziywa kuphinde kwaveza ukuthi ithempeli elenziwe ngethusi liphephe kakhulu. Nokho, empeleni, Isidingo sethusi sehle kancane kancane muva nje. Kunezizathu ezimbili, Enye isikulungi esisezingeni eliphakeme eyenziwe nge-bronze nethusi kubalulekile, Futhi okulandelayo umenzi unesigaxa se-salicon esengeziwe ekuxubeni ukunciphisa intengo yokungena emakethe yamanje, okuvusa ubucwebe kwalolu mpompi futhi kunciphise impilo yayo. Isikulufu esibi sensimbi esingenasici senziwe ngokwezomnotho futhi siqukethe ukuncipha kwe-brittleness, okuzoba nokuningi ngokuhambisana nokufunwa kwamakhasimende. Kuyaphawuleka ukuthi i-legionella ingabingeli nje ama-legionnaires’ isifo, kodwa futhi kubangela izifo ezingamahlalakhona ezingatholakali kalula.
