How to know tap seal was worn out?
Main tap will be found inside every house. This one is not belong to water supply company but own and to be maintain by the house owner. So, how to check the tap seal was worn out? It’s very simple, just try to close the tap (turn off water supply). By right there was no water going into water tank. But if the water still flow in, then just get prepare all the tools & seal.

For my case, it already worn out few weeks ago. So, I have to turn the tap off from outside of my house. Today, I’ve change the seal. Yeah…
