toilet flushing problem .

[goofy gorilla]

Hi guys...i ve just replaced the complete syphon in my toilet, because the diaphragm in the old syphon was torn and the toilet wouldnt flush....anyway i replace it with this similar one from screwfix:

http://www.screwfix.com/prods/44047...on-203mm-8?cm_re=SEARCHPROMO-_-SYPHON-_-44047

simple straight forward replacement..however ive noticed that when flushing the toilet the water doesnt come down with pressure behind it, and consequently the contents of the pan do not flush out and sometimes it takes 4 or 5 flushes....i didnt adjust anything on the syphon, left it as it was..it fitted the syphon straight out the pack..does it need priming or something or even adjusting.?...any help please...ta

did you adjust the flush volume to 9 litres

with the plugs

that was quick reply...no mate, i didnt adjust anything, left it as it was......the water in the tank is as high as i can get it, i adjusted the ball valve to this.....toilet was working fine with the old syphon, just the diaphram was torn, wish id kept that old syphon and took off the diaphram from this new one.....lol

from the picture which plug do i take out or leave in to adjust to max of 9 litres ?..

Did you cut away some of the exposed screw threads after fixing the syphon in? If they are too long they can bottom out on the pan ceramic restricting the flow. (Close coupled loo). For full flush, leave the plugs in.

airc you leave both in

check the instructions

fish them outa the trash first

no its not a close coupled loo...there were no threads exposed...it was exactly like the old syphon...quite simple to fit actually....both plugs are in so it fills 9l...how do i get the air out. ?....lost the instructions..threw them away after i fitted it..
