I'd love to answer but I'm struggling to read half these replies! English is a disgrace on this post

Sran it's not a English man that is true , an most of the time he uses his iPhone , and then he never checks the spellings !
I do apologise for that post it's really bad , I know !
All I wanted to say is that accumulator suggestion was not a good idea as there is no way accumulator will increase the mains pressure !

 

[eaton]

It won't increase it no but it will provide adequate pressure to satisfy a unvented.

 

[tamz]

More flow but it can only provide the same pressure as it gets put into it.

agree with stan if theres not enough pressure in coming an acumalator wont help
