I have just installed this water pump (260W) to the cold water pipe between my kitchen sink and outside tap in order to boost the water pressure to the outside tap as my water irrigation system is only getting a trickle of water out of it toward the end of the pipe: https://www.amazon.co.uk/gp/product/B00L90478Q/ref=od_aui_detailpages00?ie=UTF8&psc=1
The pump automatically turns on when it detects flow through it. i.e. when I turn my outside tap on you can hear the pump activate. However, the water pressure doesn't change at all when the pump has been activated. Of course it could be faulty, but as it's brand new and sounds like it's working I'm not so sure. I might just be missing something. Is my water pressure already high enough for the pump and therefore it is making no difference? Or is there something else I'm missing? I'm not sure. Any pointers appreciated.

I bought a water pressure gauge and tested it today:
Without the pump my outdoor tap has pressure of 50psi / 3.4 bar With the pump it has a pressure of 80psi / 4.5 bar. Therefore it is obviously working, so why does my hose pipe / irrigation system not perform any better? I would have though a pressure increase of 1.1 bar would have seen some performance increase. Am I missing something?
