New toilet will not clear the pan!!!

[bster]

installed a 6lt WC in place of a 9lt.

correct fall

Upstairs location

replaced offset pan connector for a standard straight pan connecter, this is used between a 90degree pan connector and the 110 branch.

run to 110 soil and vent branch = 50cm.

vent termination appears to be clear.

drop valve correctly set up.

water level in cistern correct

no blockages between cistern and pan.

water seems to fall more on one side of the pan than the other

no blockages apparent, checked inspection covers and thrown buckets of water down pan with no sign of backfilling whatsoever.

When first installed (with offset pan connector) they complained about backfilling of pan, plunged it and backfilling ceased (i put it down to the offset pan connecter but could it be something else?) hasnt done it since

I beleive it is worth cutting the the vent pipe to check for nests etc.. as in my mind it seems to be inadequate air entering the system.

any other ideas, great minds of the forum?

You mentioned water seems to fall more on one side of the pan than the other could be a badly cast pan or bleach block / blue loo etc washed down under the rim of the pan which happens with with these new flush valves................

yes bad bpan cast (Homebase jobby) - i want to make sure i have coverered all bases before they contact supplier (they supplied the suite , not me..thank the lord). It's brand spanking and no bog bleach cube has been added.

polythene, paper, cardboard, bolt, nut, washer or screw just about any thing can get under there depending on the casting you can get a mirror and check under the rim for anything obvious.........

I have checked, but will do the mirror test and report back!
