Water pressure

[BigRedBus]

Hello everyone,
I live in a purpose built flat on the second floor. Both Mains water pressure and stored water from the roof not that good and also depends how many neighbours are using water. Electric shower never worked properly tried off both mains and stored water pipes. Combi Boilar runs of the mains and the flow not very good.

If i was to combine both mains and stored water 22mm pipes together add non return check valves, would that increase water pressure? For boilar or electric shower

Not a practical option.

Get your pressure and flow checked out, also get the mains checked and see what rate you are getting. You may be able to fit a home booster, it could bring the mains up to a better spec.
