Can a plumber give me a simple answer to what I think is a simple question?
I'm working with a building in Thailand to improve the water supply. Currently we have a pump and pressure tank that can just get up to 2.5Kg/cm (2.5 bar). This pressure is just enough. Problem is when it reaches pressure it switches off and only comes back at 1.7 bar, not enough for most rooms. So we get a varying water supply from a trickle to a surge. If we leave the pump on continuously we use far too much electricity.
We have a lovely electric pump, 8 amp so plenty of power, and a header tank
4 metres above the pump.Can I just change the water pump part - is that the impeller?
If I change it for a pump that can get up to 3.5 bar is that the same as a pump that can give a 35m lift?
Thanks,
