I raised this topic before. We have a toilet that has a very poor flush. It flushes ok insofar as emptying the cistern goes it just doesn't have enoug h oomph to clear the contents of the pan.
I have replaced the innards of the cistern twice and fiddled with the inlet tube, (its not close coupled, the cistern sits about 300mm higher than the toilet itself). Without actually moving the toilet itself I broke the outl et connection at the rear but could see no sign of a blockage.
We are in a soft water area so limes scale can be ruled out anyway I've loo ked and can see nothing.
SWMBO says she's had enough and is going to call in the professionals but I 'd like to know what their answer would be. (I just know their immediate so lution is to replace the innards but that won't work.)
Replace the whole shebang ? What could possibly be wrong with the existing one which worked well enough for years. ?
It defeats me.
