Mu dongosolo lamadzimadzi, valavu imagwiritsidwa ntchito kuwongolera komwe madziwo akupita, kuthamanga kwake, ndi kuyenda kwake. Pakumanga, ubwino wa kuyika valavu umakhudza mwachindunji momwe ntchitoyo imagwirira ntchito mtsogolo, kotero iyenera kuyamikiridwa kwambiri ndi gawo lomanga ndi gawo lopanga.

Vavu iyenera kuyikidwa motsatira buku la malangizo ogwiritsira ntchito vavu ndi malamulo oyenera. Pakumanga, kuyang'anitsitsa ndi kumanga kuyenera kuchitika. Vavu isanayikidwe, kuyiyika kuyenera kuchitika mayeso a kuthamanga atayesedwa. Onetsetsani mosamala ngati zofunikira ndi chitsanzo cha vavu zikugwirizana ndi zojambulazo, onani ngati mbali zonse za vavu zili bwino, ngati valavu yotsegulira ndi yotseka ingazungulire momasuka, ngati pamwamba pa kutseka pawonongeka, ndi zina zotero. Pambuyo potsimikizira, kuyiyika kungathe kuchitika.

Vavu ikayikidwa, njira yogwirira ntchito ya valavu iyenera kukhala pafupifupi 1.2m kutali ndi nthaka yogwirira ntchito, yomwe iyenera kugwedezeka ndi chifuwa. Pakati pa valavu ndi gudumu lamanja zikadutsa 1.8m kutali ndi nthaka yogwirira ntchito, nsanja yogwirira ntchito iyenera kukhazikitsidwa kuti ikhale ndi valavu ndi valavu yotetezeka yokhala ndi ntchito zambiri. Pa mapaipi okhala ndi mavalavu ambiri, mavalavu ayenera kukhala okhazikika pa nsanja momwe angathere kuti ntchito ikhale yosavuta.

Pa valavu imodzi yoposa 1.8m komanso yosagwiritsidwa ntchito kawirikawiri, zida monga gudumu la unyolo, ndodo yowonjezera, nsanja yosunthika ndi makwerero osunthika zingagwiritsidwe ntchito. Vavu ikayikidwa pansi pa malo ogwirira ntchito, ndodo yowonjezera iyenera kuyikidwa, ndipo valavu ya pansi iyenera kuyikidwa ndi chitsime cha pansi. Pofuna chitetezo, chitsime cha pansi chiyenera kutsekedwa.

Pa tsinde la valavu pa payipi yopingasa, ndi bwino kukwera moyimirira mmwamba, m'malo moyika tsinde la valavu pansi. Tsinde la valavu limayikidwa pansi, zomwe sizikugwira ntchito bwino komanso kukonza, komanso zosavuta kuwononga valavu. Vavu yolandirira siyenera kuyikidwa mopanda ntchito kuti ipewe kugwira ntchito molakwika.

Ma valve omwe ali pa payipi yozungulira mbali ayenera kukhala ndi malo ogwirira ntchito, kukonza ndi kumasula. Mtunda womveka bwino pakati pa mawilo amanja suyenera kuchepera 100mm. Ngati mtunda wa payipi ndi wopapatiza, ma valve ayenera kuzunguliridwa.

Pa mavavu okhala ndi mphamvu yayikulu yotsegulira, mphamvu yochepa, kupunduka kwakukulu komanso kulemera kwakukulu, valavu yothandizira mavavu iyenera kuyikidwa isanayambe kuyikidwa kuti ichepetse kupsinjika koyambira.

Mukayika valavu, mapaipi ayenera kugwiritsidwa ntchito pa mapaipi omwe ali pafupi ndi valavu, pomwe mapaipi wamba ayenera kugwiritsidwa ntchito pa valavu yokha. Nthawi yomweyo, panthawi yoyika, valavu iyenera kukhala yotsekedwa pang'ono kuti valavu isazungulire kapena kusinthika.

Kukhazikitsa bwino kwa valavu kuyenera kupangitsa mawonekedwe amkati mwa valavu kuti agwirizane ndi njira yoyendera ya sing'anga, ndipo mawonekedwe okhazikitsa agwirizane ndi zofunikira zapadera ndi zofunikira pakugwira ntchito kwa valavu. Muzochitika zapadera, samalani kuyika mavalavu okhala ndi zofunikira pakuyenda kwapakati malinga ndi zofunikira za payipi yoyendetsera. Kapangidwe ka valavu kayenera kukhala kosavuta komanso koyenera, ndipo wogwiritsa ntchito ayenera kukhala wosavuta kupeza valavu. Pa valavu yokweza, malo ogwirira ntchito ayenera kusungidwa, ndipo ma valavu a mavalavu onse ayenera kuyikidwa mmwamba momwe angathere komanso molunjika ku payipi.
