Experience With Installing Water Pressure Booster Pump

[losheng 0]

Hey, guys, I'm wondering if any of you had any experience with installing a water pressure booster pump at your place? I'm interested to know how much it cost, how much space it takes up, how much electricity bill, and of course, any recommendation for brand/configuration/contractor!

Any information much appreciated!

I want to know too... anyone? one pump for the entire house or do we need several?

I have done quite a bit of research, and this is what I've found:

1. PUB's regulation only allows for indirect connection. ie. you are not supposed to connect a pump to 'suck' water directly out of PUB's mains. This is to prevent affecting your neighbour's water pressure everytime the pump kicks in. A system that meets PUB's criteria will consist of a water tank, a pump, a pressure tank, and the supporting electronics and pressure sensor to turn on and off the pump. A very reasonably priced system for small house holds that I've come across is the WILO CO/T all-in-one system, taking up a foot print of about 1m x 1m x 1m, costing 3-4k, excluding installation cost. The pump for this system runs on a 3-phase electrical supply, so your place will need to have this. Here's a contact to find out more about this setup:

Just beware of the quotations from other contractors - some may proposed systems in excess of 10k, which might be totally an overkill for small households.

2. Due to cost, there are residents that connect pumps to the mains directly anyway. If the neighbours start to suffer from fluctuating water pressure, they may lodge complaints to PUB, and PUB will come looking for the pump in the neighbourhood. The smallest pump from Grundfos that is normally deployed in industrial applications sometimes gets used for this purpose: the MQ3-35. There are also people that brings in small pumps from M'sia, where is very common for households to install their own pumps to boost water pressure. Such deployment is against the regulation, and you'll stand the risks of being caught.

I hope this helps!

Hi losheng,

Do you know how much does the Grundfos MQ pump cost? And which store sells it?

Thanks!

You can get in touch with Grundfos Singapore to make enquires:

<http://www.grundfos.com/web/homesg.nsf>

The pump costs about $7-800, excluding installation.

Before you venture down that path, it will help if you first check with PUB to see if the water pressure problem at your area is typical. Singapore's water supply is distributed by gravity, so you may have problems if your house is located above 35m (depending on the relative height between your house and the reservoir that's serving your area). Otherwise, good plumbing and routing design within the house can make a huge difference to the supply flow. This is the probably the first problem source that you want to rule out. In my own case, replacing the incoming pipe from a 0.75' to a 1.5' one resolved the problem without the need to resort to any of the above expensive means.
