I just bought 5 litres of disinfectant and pour all 5 litres into my home's drainage pipes

I used this brand. I pour into shower traps, kitchen plus bathroom and sink traps.

Hopefully, if there's any Covid Virus inside those drainage pipes, they will be eliminated.

Good brand, I use it as mouth gargle too.

you are better off using water mixed with bleach solution. Cheaper too.

I would pour a gallon into Batu cave.

This is normally used for cleaning surfaces. You’re just cleaning the inner surfaces of the pipes.
