Kafin a gwada bawul ɗin toshewa, ana ba shi damar shafa wani Layer na mai mai laushi wanda ba shi da sinadarin acid a saman rufewa. Idan ba a sami wani ɗigon ruwa ko babban digo na ruwa a cikin ƙayyadadden lokacin ba, ya cancanta. Lokacin gwajin bawul ɗin toshewa na iya zama gajere, gabaɗaya ana ƙayyade shi azaman mintuna 1 zuwa 3 bisa ga diamita na asali.

Ya kamata a gwada bawul ɗin toshe iskar gas don tabbatar da cewa iskar tana da ƙarfi sau 1.25 fiye da matsin lamba na aiki.

6. Hanyar gwajin matsi na bawuloli na diaphragm Gwajin ƙarfi na bawuloli na diaphragm shine a shigar da matsakaici daga kowane gefe, a buɗe faifan bawuloli, sannan a rufe ɗayan ƙarshen. Bayan matsin lambar gwajin ya tashi zuwa ƙimar da aka ƙayyade, a duba ko babu ɓuɓɓuga a jikin bawuloli da murfin bawuloli. Sannan a rage matsin lamba zuwa matsin lambar gwajin rufewa, a rufe faifan bawuloli, a buɗe ɗayan ƙarshen don dubawa, sannan a wuce idan babu ɓuɓɓuga.

7. Hanyar gwajin matsi na bawuloli masu tsayawa da bawuloli masu matsi

Don gwajin ƙarfi na bawuloli masu tsayawa da bawuloli masu matsewa, yawanci ana sanya bawuloli masu haɗuwa a cikin rack na gwajin matsi, ana buɗe faifan bawuloli, ana allurar matsakaici zuwa ƙimar da aka ƙayyade, kuma ana duba jikin bawuloli da murfin bawuloli don gumi da ɓuɓɓuga. Haka kuma ana iya yin gwajin ƙarfi akan yanki ɗaya. Ana yin gwajin rufewa ne kawai akan bawuloli masu tsayawa. A lokacin gwajin, tushen bawuloli na bawuloli masu tsayawa yana cikin yanayi a tsaye, ana buɗe faifan bawuloli, kuma ana gabatar da matsakaici daga ƙasan faifan bawuloli zuwa ƙimar da aka ƙayyade, kuma ana duba marufi da gasket; bayan cin nasarar gwajin, ana rufe faifan bawuloli kuma ana buɗe ɗayan ƙarshen don duba ko zubewa. Idan za a yi gwajin ƙarfin bawuloli da hatimi, za a iya fara yin gwajin ƙarfi, sannan a rage matsin zuwa ƙimar da aka ƙayyade don gwajin hatimi, kuma ana iya duba marufi da gasket; sannan ana iya rufe faifan bawuloli kuma ana iya buɗe ƙarshen fita don duba ko saman hatimi yana zubewa.
