HDB Low Water Pressure: Phone Hotline

For those living near the top floor of HDB blocks, you may experience low water pressure since the water tanks are typically built at the rooftop of HDB flats.

The pressure exerted by a column of liquid of height h and density ρ is given by the hydrostatic pressure equation $\displaystyle\boxed{p=\rho gh},$ where g is the gravitational acceleration.

By this equation, you can understand why those at the top floors experience low water pressure, due to the low height h (from the water tank). There is probably a need for a pump to increase the pressure. For low floors, it is typically ok, the natural pressure should be enough to make the water flow fast.

My Experience with Low Water Supply

I experienced unbelievably quick action by PUB on Chinese New Year, around 9pm. I called the PUB hotline due to very low water pressure (insufficient for even bathing). Mentally, I was prepared that probably they could only fix it the next working day (which is 2 days later).

To my amazement, a repairman arrived 15-20 minutes later, and proceeded to fix the water tank. The water pressure was back to normal in just half an hour from the time I dialed the hotline. I was quite impressed by the high efficiency.

I am not sure what caused the problem in the first place though. This problem of low water pressure has been reported by Channel News Asia.

HDB Low Water Pressure What To Do

Firstly, you should check with neighbors on the same floor whether they experience the problem of low water pressure. This is to confirm whether the problem is with the water tank pump/pipes, or an isolated problem only pertaining to your unit.

If your neighbors also experience low water pressure, then most likely it is a problem pertaining to the water tank pump/pipes. You should dial the PUB hotline (1800-2255-782) and inform them of the low water pressure. They will liaise with the Town Council and send a technician to investigate. (The service is free of charge.)

If the situation still does not improve, you may wish to purchase this “Wind Storm” High Pressure Shower Head. Basically, it turns a low pressure stream of water into a high pressure spray of water, to the extent that you can feel a “wind” blowing. It also saves water so it will pay for itself in the long run (by reducing your water bills).

One of the most popular and best brands of water bottles is Nalgene, which is made in the USA. It is BPA free, which is very important to avoid drinking toxic plastic particles that may leach into your water. (I think by now Singaporeans know it is not good to reuse Coca Cola bottles as your water bottle; 10 years ago it was very common to do that.) It is quite hard to find Nalgene bottles in supermarkets. NTUC Fairprice, Giant does not seem to carry them in their stock. Interested buyers may purchase Nalgene bottles from Qoo10 (see image link below). Do choose this store as it has many positive reviews, it has an actual store in Pasir Ris, but buying online would be much more convenient.

Free Water Saving Kit (Singapore)

I believe this is not new, but it is the first time I heard of it. Anyway, it is free, so do feel free to request for a sample at the PUB Official Website.

PUB has revamped the packaging of its popular water saving kits featuring its mascot Water Wally. A set of thimbles with three and four holes allows residents to have greater flexibility in regulating their tap’s and showerhead’s flow rates. Water Wally stickers with specific messages are also included in the kit to act as reminders of good water saving habits in homes. ​
