Nzila yakubelesya vvalavu ninzila yakulanga-langa akubamba vvalavu. Nokuba boobo, twaambo tutobela tweelede kubikkilwa maanu aawo notubelesya vvalavu.
①Valavu yakupya kapati. Eelyo kupya nokwatanta kwiinda 200°C, mabbulutu alapya mpawo alalampa, eecho nchuubauba kuchita kuti chijazyo cha valve chizwe. Aachiindi eechi, mabbuluti ayelede "kuyuminizyigwa akupya", alimwi tacili kabotu pe kuchita kujatilila kwakupya muchiimo chakujalwa kwavalvu, kuchitila kutabilila chisiko chavalvu kuti chifwide akukatazya kujalula kumbele.
②Muchiindi eecho nikupya munsi a 0°C, kobikkila maanu kujalula pulagi yachibbula cha valve kuti ma valve alesye busi amaanzi kuti agwisye maanzi aajisi busani amaanzi aabungene, kuchitila kutabilila kupya akutyoka kwa valve. Kobikkila maanu kukubamba kupya kwamavalvu aatakonzyi kugwisya kuyoboloka kwamaanzi amavalvu aabeleka chiindi achiindi.
Nsinga yakupakila tayeelede kusinikizyigwa loko, mpawo kubeleka kwachisiko chavalvu kweelede kuzwidilila (nchintu chibi kuyeeya kuti nsinga zyakupaka kaziyumu, nkubotu, ziyoofwambaanya kubola kwachisiko chavalvu akuyungizya nguzu zyakubeleka). Muchiimo chakuti kakunyina nzila zyakukwabilila, kupaka takukonzyi kuchinchwa naakuti kuyungizigwa muchiimo chakusinikizyigwa.
④Muchiindi chakusilikwa, zintu zitali kabotu zijanika mukuswiilila, kununkizya, kubona, kuguma, azimwi zyeelede kulanga-langwa kabotu-kabotu akaambo katwaambo, mpawo eezyo zyeendelana anzila zyabo beni zyeelede kugwisigwa muchiindi cheelede;
Sikubelesya weelede kuba abbuku lyaalubazu lyakulemba naakuti bbuku lyakulemba, mpawo abikkile maanu kulemba kubeleka kwamavwili aasiyene, ikapati mavwili amwi aayandika, mavwili aapya kapati alimwi amavwili aajisi nguzu kapati alimwi amavwili aalibedelede, kubikkilizya azibelesyo zyabo zyakutumizya. Kweelede kuzyibwa kwaalilwa, kusilikwa, zibeela zyakucinca, azimwi, eezyi zintu zilayandika kuli sikubelesya lwakwe mwini, basikubamba alimwi abasikupanga. Chita bbuku lyaalubazu lijisi mikuli iimvwika, eeyo iigwasya kuyumya bweendelezi.
