Amathangi okucindezela amanzi adala umfutho wamanzi ngokusebenzisa umoya ocindezelwe ukuphusha amanzi phansi. Lapho i-i-valvekuyavuleka, umoya ocindezelwe ethangini uphushela amanzi ngaphandle. Amanzi aphushwa ngepayipi kuze kube yilapho ingcindezi yehla iye enanini eliphansi elisethiwe emshinini wokucindezela. Uma isilungiselelo esiphansi sesifinyelelwe, inkinobho yokucindezela ixhumana nepompo yamanzi, iyitshela ukuthi ivule ukuze iphushe amanzi engeziwe ethangini nasendlini. Ukuze uthole usayizi olungile wethangi lokucindezela elidingekayo, udinga ukucabangela ukugeleza kwepompo, isikhathi sokusebenza kwepompo kanye ne-psi yokusika/ukusika.

Kuyini umthamo wokwehla kwethangi le-pressure?
Umthamo wokwehla inani elincane leamanziukuthi ithangi lokucindezela lingagcina futhi lilethe phakathi kokuvalwa kwephampu kanye nokuqalisa kabusha kwepompo. Ungaphambanisi umthamo wokwehla nosayizi wevolumu yethangi. Uma ithangi lakho likhulu, ithonsi elikhulu (amanzi agciniwe empeleni) uzoba nalo. Ukudonsela phansi okukhudlwana kusho isikhathi sokusebenza eside namalophu ambalwa. Abakhiqizi ngokuvamile batusa isikhathi esincane sokusebenza somzuzu owodwa ukuze injini iphole. Amaphampu amakhulu namaphampu anamandla amahhashi aphezulu adinga izikhathi zokugijima ezinde.

Izici ekukhetheni usayizi wethangi elifanele
• Into yokuqala okudingeka uyazi izinga lokugeleza kwepompo. Impompa ngokushesha kangakanani? Lokhu kusekelwe kumalitha ngomzuzu (GPM).

• Khona-ke udinga ukwazi isikhathi esincane sokugijima sepompo. Uma izinga lokugeleza lingaphansi kuka-10 GPM, isikhathi sokusebenza kufanele sibe ngu-1 GPM. Noma isiphi isilinganiso sokugeleza esikhulu kuno-10 GPM kufanele sisetshenziswe ku-1.5 GPM. Ifomula yokunquma amandla akho okudonsa ukugeleza x isikhathi esidlulile = amandla okwehlisa.

• Isici sesithathu isilungiselelo sokushintsha ingcindezi. Izinketho ezijwayelekile ziyi-20/40, 30/50 kanye no-40/60. Inombolo yokuqala ingcindezi yangemuva kanti inombolo yesibili ingcindezi yepompo yokuvala shaqa. (Abakhiqizi abaningi bazoba neshadi elikutshela inani lokudonsela phansi ngokusekelwe kumshini wokucindezela.)

Ingabe Usayizi Wekhaya Ubalulekile?
Uma wenza usayizi wethangi, isithombe esiyisikwele sekhaya lakho asibalulekile kunokugeleza nesikhathi sokumpompa. Lokhu empeleni kuhlobene nokuthi mangaki amalitha ngomzuzu owasebenzisayo ekhaya lakho ngesikhathi esinikeziwe.

Ithangi likasayizi olungile
Ithangi lakho likasayizi olungile lisekelwe kuzinga lokugeleza eliphindwe ngesikhathi sokugijima (elilingana nomthamo wokwehla), bese kuba isilungiselelo sakho sokushintsha ingcindezi. Uma izinga lokugeleza liphakeme, ithangi elikhulu ongalisebenzisa.
