Not able to put pressure in vessel

[Anthony fabri]

Had a main water leak lately and fixed it it had been there for a few days and the boiler wasn't working after the repair I tried to pressurize the vessel in the hot press but couldn't pump air in I took out the valve stem and inserted a blunt stick in but it wouldn't go in seems like it's hitting something spongy or rubbery. Tried to put up the water pressure to 1 bar but it goes up and straight away down within seconds. Can anyone have a clue whats happening the boiler is a vaillant combi boiler ecotec 24 and it's fitted in the attic

Yes, you’re not doing it correctly. Which country are you based in, as certain regulations may apply, gas safe in the U.K.

I’ve had the bladder stuck to the outer case before now you have to pump it upto 6 bar for it to realise if it does
