Greenstar 25/30is top up pressure with key ?

[barneybodge]

Hi all,

We have a worcester greenstar 25/30is and I need to top up the pressure with the key but have forgotton how. The supplied manual is next to useless.

I remember the plumber showing me where to insert the plastic key, turn this and turn that, watch pressure gauge, set and done.

Anyone care to remind me ?

Many thanks for that

Its back up to about 1.2 bar where the plumber had originally set the dial.

However I am a bit worried that it had slipped down to 0 bar (absolute zero) and took a lot of water to re-pressurise. Could this be a mains leak or maybe ch system leak ?

Thanks again

Does sound like a leak

Have a good look around .

The leak will be from the CH system, check all pipework and radiators.

However if this has not been topped up since it was installed and that was over a few months ago then it might just have been some air released from the AAV or have you blead a rad??

Thanks for the replies.

This is the first time ive topped up since it was installed last year. It dropped a bit a few days after installation and ive only noticed it was at zero today.

There are no visible leaks and I think I may have bled a few rads a few months ago.

I wont worry about it unless it drops really low again.

Thanks again, great forum
