Baxi 105e pressure & re-pressurising

trig1982

Hi I am trying to pressurize my boiler system, I have connected my flexipipe to the cold outlet and heater return, the 2 chrome taps on the right, heating works fine now but when i turn the hot water tap on the pressure lowers again,

Also when I try to remove the flexipipe water just comes flying out of the system again and the pressure drops so have to tighten the flexipipe back up.

Can anyone suggest anything.

Thank You

Have you turned the two taps off for the filling loop after filling the heating. Its a closed system so when pressurized you just turn the taps off and you can disconnect the filling loop. If you leave the taps open the the water will be drawn through the hot water system. I assume you have a combi boiler.

yes I turned the taps off but there is only one set of taps and they are on the other side of the pipes so everything that is above in the boiler itself comes flooding out.
I have managed to let it drain and replace caps and pressure is just at 0.5 Bar. I will have to get an extra bit of piping with taps on so i can close it off this side. Thanks

It seems odd that there is not a tap on either end. Is it not possible to close the mains water fill side off and leave the flex in place. On my combi I cannot remove my filling loop.
