release the pressure from a radiator bleed valve as you would when bleeding them.
i think you have a problem with your boiler.
shut your mains water stopcock, then release the pressure back down to 1.5 bar, then run your heating for a few mins then turn it off and check if pressure is still at 1.5 bar.
if it is then turn your mains stopcock back on and see if your pressure gos back up.

does the pressure gauge go back down when heating turned off ?
the leaking water is just the prv releasing water as this valve activates at 3 bar or above.
