But he only has a 150W pump. I suspect the "other" switches you talk about are for ,say, a 300W pump.
My 200W pump works fine for a three storey house with a shower on the top floor. It is in its own space and may cycle on and off but they are made to do that. Water doesn't pulsate and I can't hear it so.
In Indonesia I had a small pump that I did adjust/measure using a pressure gauge but only because I borrowed one from the Instrument shop.
