Get one that services at least 6-7 outlets then. Ensure anti vibration mat are installed under the pump. This one looks better with one extra feature.

Also, ensure there's adequate filtration before the pump ideally after (point of entry) the water meter to filter out the pump killers: sand rust silt mud. If this is done then ensure tangki is washed thoroughly first to get rid of any resident pump killing matter before plumber installs the pump.

Sums it up pretty much in principle. The vibration will be transmitted outwards from where the pump is located. If not attenuated, it might be nuisance at best or the pump night be prone to "walking" or be transmitted along the piping. For that where piping is known to hit the other part of the roof support, place a small piece of anti vibration mat (cut to size) in between to shield it from this tendency.

Note: everyone upstairs might still hear the pump's soft humming when it's operating. That can't be avoided but if your plumber has done something marvellous that reduced the humming such that the only time you're aware that it's operating is when you're directly under it, do share. I want to know how also.
