Best concealed cistern

Anonymous user 01/03/2024 - 3.01 PM

I have installed a rimless back to wall toilet with a concealed cistern, both from Easybathrooms. But the flush is very poor. Just not enough power in the flush to shift anything first time. Takes 3 or 4 flushes. I've changed the cistern for another one the same but still no difference. If I pour a litre jug of water down the loo at same time as flushing, it's fine. I've now swapped to a normal type toilet pan, which is better but the flush only just manages to shift paper etc. Can anyone recommend a concealed cistern with a good strong flush? To be honest the rimless toilet was far nicer and better quality than the one I've replaced it with. But I'm not sure if these 6 litre dual flush cisterns are compatible with rimless toilet pans. The water level in the cistern is higher than the line inside, I've got it right to top of overflow pipe. All water empties from cistern when flushed. I can't raise the cistern any higher as its in a unit. Maybe I can just replace the flush valve with a decent one, saving a few quid over a whole new cistern. I'd prefer a higher capacity than 6L but not sure if one would fit in the 500 unit. Easybathrooms are saying it's not a problem with there products, it's an installation issue! Craig: There is about 4 inches of pipe on the flush pipe before the bend. I've also got the pipe running downhill slightly into the pan to aid the flush. It's an Apache dual flush concealed cistern on the Easybathrooms website. It's 320 H x 335 W x 140 D. I've installed it as high as possible in the 500mm unit. I will double check the pipe going into pan itself.
