It was time to service our house's master water filter. I called the serviceman and he came fully armed with all the necessary equipments. This was how our filter looked like. The filtered sediments are good enough to make pots and pots of black coffee.
The filter consisted of a long piece of fabric-like material. The serviceman spread it out. Using high pressure water gun, the guy took 15 minutes to clean it.
Then the filter was rolled into it's original position.
In half an hour, the whole process completed. RM60 paid. Now I enjoy clean water.
I wonder if it's common to have such water quality which requires filtration.
