Kutseka kawiri & kutuluka magazi (DBB)

Mpira ukatsegulidwa bwino kapena kutsekedwa, chinthu chotumizira chomwe chili pakati pa thupi chimatha kutulutsidwa ndi zida zotulutsira madzi ndi zotulutsira madzi. Kuphatikiza apo, kupanikizika kochulukira komwe kuli pakati pa valavu kumatha kutulutsidwa mpaka kumapeto kwa kupanikizika kochepa pogwiritsa ntchito mpando wodzipumira.

Kutseka mwadzidzidzi

Mabowo ojambulira a compound amapangidwa ndipo ma valve ojambulira a compound amaikidwa pamalo omwe tsinde/chipewa ndi thupi lochirikiza valavu yam'mbali. Pamene kutseka tsinde kapena mpando kwawonongeka kuti kutuluke madzi, chitha kugwiritsidwa ntchito kutseka kachiwiri. Valavu yofufuzira yobisika imayikidwa m'mbali mwa valavu iliyonse yojambulira ya compound kuti chitha kutuluka chifukwa cha ntchito ya chinthu chotumizira. Pamwamba pa valavu yojambulira ya compound ndi cholumikizira cholumikizira mwachangu ndi mfuti yojambulira ya compound.

NSEN ikutsatira mosamalitsa ntchito zokonza zaulere, kusintha kwaulere ndi kubwezeretsa kwaulere mkati mwa miyezi 18 valavu itatha ntchito zakale kapena miyezi 12 itatha kuyikidwa ndikugwiritsidwa ntchito pa payipi pambuyo pa ntchito zakale (ndipo imayamba poyamba). 

Ngati valavu yalephera chifukwa cha vuto la khalidwe panthawi yogwiritsa ntchito mapaipi mkati mwa nthawi ya chitsimikizo cha khalidwe, NSEN ipereka chitsimikizo cha khalidwe chaulere. Ntchitoyi siidzatha mpaka kulephera kukhazikika ndipo valavuyo ikugwira ntchito bwino komanso kasitomala atasaina kalata yotsimikizira.

Pambuyo pa nthawi yomwe yatchulidwa, NSEN imatsimikizira kuti idzapatsa ogwiritsa ntchito ntchito zaukadaulo zabwino pa nthawi yake nthawi iliyonse yomwe chinthucho chikufunika kukonzedwa ndi kusamalidwa.
