Pump to boost low pressure in a condo?

[mran66]

Visited a friend who recently bought a condo which seems to have very low water pressure all the time. To improve the situation in bathroom, he had bought  a cheap booster pump from Lazada and simply put in water heater inlet line. It kind of makes it a bit better, but nothing comparable what e.g I have in my house with a Mitsu WP pump.

 

I was wondering whether the EP series Mitsu pump which has the flow switch in addition to pressure switch would work in his condo if installed right after the water meter, boosting the pressure in all rooms? What is the functional logic in EP series with the pressure and flow switches?

 

The small booster pump with (flow sensor/switch) logically works OK in his case - it simply starts if water starts flowing, keeps running all the time until flow stops for whatever reason. In his case the pump indeed should work like that i.e in case the condo water supply would be so bad that no flow at all without the pump running, the pump should not start at all. The pump should simply be a booster pump which only runs if there is something to boost i.e some flow (which start if a tap is opned and stops when tap closed). If zero water coming in from condo supply, pump should not start at all.

 

The WP pump I have would not work in his case, but would EP? If not, anything else suitable for his case?
