Njengensimbi ebaluleke kakhulu futhi ebalulekile ekwakheni umnotho wezwe, amapayipi ensimbi angenamthungo asetshenziswa kabanzi emikhakheni efana nokwakha, ukucubungula imishini, kanye nobunjiniyela bamapayipi (ukuthutha uketshezi nezinto eziqinile ezifana namanzi, uwoyela, igesi, amalahle, kanye nomusi webhoyila). Ngenxa yezindawo ezahlukene zokusetshenziswa kanye nokusetshenziswa, kusadingeka ukukhetha izinto ezifanele kanye nezindinganiso lapho ukhetha ukugwema imfucuza kanye nezici ezingaphephile.
