Requirements
I was looking for new water pump for my house. My criteria was quite simple, the water pressure is still high if I open 2 bathrooms and washing dishes at kitchen at same time.
At same time the water pump has good support and affordable.
So I would like to know how many power or horse power needed to support my requirements.
Water Pump Power Estimation
So I went to my usual hardware shop where they have set up a demo set on Tsunami water pumps.
Tsunami Pump – 200W
Imagine one water tap is one bathroom. For 200W the outcome as follows
1) 1 tap open – water pressure high
2) 2 taps open – water pressure medium
3) 3 taps open – water pressure low
Tsunami Pump – 1100W
Imagine one water tap is one bathroom. For 1100W the outcome as follows
1) 1 tap open – water pressure high
2) 2 taps open – water pressure high
3) 3 taps open – water pressure high
Decision
I decided to buy Tsunami water pump 400W because I notice for 200W after opening 2 water taps, the water pressure becomes slow.
Besides, Tsunami pump 400W is still affordable for me at around RM450.
