hi,

i'm noob in staying high-rise condo, about 25 storeys, but planning to get one.

i've read condo residences complaining about low water pressure and no water issue.


my noob questions:

1) condos, in general, dont have direct main pipe, right?

2) i assume the main pipe goes up to roof's tanks, and then distributed downwards?

3) if i'm on top living floor, say floor #20, i'm having higher chances of getting more water (higher pressure), than those staying at lower level?

of course, the tanks are replenished by the main pipe anyway, sooner or later the tanks will be emptied but main pipe is slower/lesser pressure to go up to fill up tanks faster ... just guessing...


my concern is this. should i get a small water tank and store water inside my unit, just as backup? just in case, sudden no-water from tanks, etc etc


thanks for reading and commenting a new noob planning to stay in high-rise condo

Lower level normally have higher water pressure and vice versa.

Bro, currently I'm staying in 22nd floor. Hope can help you abit.

1) Not direct, just distribution.

2) I'm not so sure, but for my condo I think the tanks at downstairs, then pressure it up flowing down, something like that.

3) Usually our unit will get more water than downstairs.

If you can get a tank for your unit, it will be better, but have to make sure there is a space for you to do so.

Mine is highest floor, so we can put at ceiling area.

stay in condo shouldn't have water pressure problems la.
normally the lower the unit the higher the pressure but some condos have tanks in the middle and also at the very top.
Btw I'm at the second highest floor, no problem with pressure, it's sufficient.

For 22 Storey, a roof tank would be required for cold water distribution. Usually incoming water would flow into suction tank at lowest most floor, and from there pump upward to the roof tank.

An intermediate break tank would be introduced at certain level of floor if the building exceed certain height.

And for a good developer, booster pump with a standby would be used for 3-4 top most floor, the pressure servicing the 5th highest floor and below shall be good enough from direct roof tank..

If you're at highest unit, and pressure running low, check the roof pump...

Want to know more, PM me....haha

thanks all for the insights

just gotten more info from the condo chat group ... someone "tutup" the tangki air bawah LOL LOL

i think this condo's design is per greeny88, tank at ground floor.


it seems this "problem" always surfaces in any apartment/condo. some culprits will purposely close/turn off the tank or neighbor's tank inlet.

kinda rude and selfish tenants.

Im having similar water issue.
Top floor is 14th. Im on level 12.
Water pressure is low, maybe due to rusted pipe.
Someone checked the pressure outside my house, he said it is strong. So they suggest the problem is in my house pipe.

Either get plumber to check or install water pump... very expensive... =(

how old is the building?

about 20yrs old

If install a booster pump in the meter closet, just for 1 unit, will it affect water pressure for other units on the same floor?

Something like this

Different condo probably have different ways of installing the pumps, for a condo which I used to stay (10 floor total), the maintenance guy told me only the top few floors are being supplied through water pumps installed on the roof, the rest of the lower floors are just using normal water supply. Hence my unit on the top floor always have high water pressure, except sometimes when the pump rosak, then pressure become super low.
