Water pressure/water softener/reverse osmosis filter

Anonymous user 23/02/2024 - 3.00 PM

Hi, I am looking to fit a water softener on the ground floor of a property so that all of the water supply in the property is softened. Then I want to fit a reverse-osmosis filter in the kitchen on the third floor. The filter requires 2.5 BARS of pressure. The pressure measurement from the 22mm pipe end on the 3rd floor is 1.9 BAR. Would stepping the down to a 15mm pipe increase the pressure sufficient enough for the filter to operate? Thanks.

Are you a tradesperson and able to answer this question?

Firstly, we can't increase the dynamic (working) pressure from the incoming main without introducing a pump or increasing the main pipe itself. The reality is that when you put your thumb over the end of a length of hose you are changing only the flow dynamics in the hose. You will need to consider the longer the run the more pressure loss you will have.
