7 maut selepas cuci tangki najis

[hellspermaster]

Kalau ikut SOP, masa turun kena bawak alat pengukur udara tu dulu.
Tapi biasa la, kat malaysia pun jarang ada orang yang ikut.

Kat malaysia pon dah ada kes sama mcm ni. X ingt tahun bila. Last skali, bomba dtg turun amik mangsa.

Untuk apa yer cuci tangki najis..?:-?

If a septic tank is not cleaned regularly (within 1 year for smaller tanks), toxins and antibacterial substances build up killing the vital bacteria that break down the waste. Many household cleaners build up sludge and solid waste in the septic tank and drainfield lines.
