Method of checking the pipes (Proposed by Pua)

1. Open all water lock to allow water fully fill the water tank & reach all accessing points.
2. Write down the final reading on meter (when the tank was fulled, it suppose to stop). Leave the main tap open.
3. After few hours or next day, drop by to take the reading again.

If the reading changed, then bad news.
* Check whether there is any water mark on wall (where the pipe concealed) or on the ceiling of family hall (where the water tank placed).
* Worst case there were no water mark and the meter reading still keep on "updating", then it means the underground pipping problem.

p.s. Some of our friends suggested to installed the water pump at the first place then only proceed with the same step as above. Because this allow us to check all pipping in our house for the ability of carrying pressure too.
According to expert, those pipping used in our house can only take maximum 3 bar pressure only, any more than that was highly not recommended.
