New toilet won't flush paper

You might have bought an Asian market toilet that isn't designed to flush paper. Did you buy it cheap?

I bought it from the link above (Soak.com) - seemed to be uk company?

Which pan is it? Be interesting to see if any of the reviews mention the same problem.

This is the pan

Can't see any mention of this problem on either the pan or cistern reviews

Does it definitely not flush the paper on the second go when it's wet? He is correct in the sense new cisterns are pitiful when compared to older style toliets. I never though it would actually flush anything when I changed over to a new type but it does go if you press both buttons and hold it down so the water is released fully .

Terrible design though.

The cistern appears to be for an optimum 6 litre flush pan.
The horizontal line marked below the writing on the rear of cistern is the 6 litre water line to which the cistern should be filled.


The float(the white box on the filler valve on the right hand side)looks to be as high as it will go.This is cutting off the water before it reaches the 6 litre line.
Look at the photo which someone put up showing the cistern internals.


The float valve has an internal tube(see the notches on this part of the tube showing at the bottom)which twists out of the outer tube thereby extending it.This allows for raising the height of the filler valve and thereby greater travel of the float.
This should be extended to the required level prior to fitting the filler valve,it then locks in place quite like a bayonet light bulb fitting--see the vertical lines of notches at the bottom.Often securing with a plastic ring or a push through clip like a bedside light switch.

Now either the filler valve is extended to it's maximum or it was not checked and adjusted when fitted.
If not extended to the right height then it is really very difficult to get your hand into the cistern and to twist the outer tube out of the locking notches then extend and twist locked again.Cannot get a grip because the tube is too close to the cistern,cannot manage to rotate your wrist and it is a real pain to locate the notches.The satisfactory way is to disconnect water supply,disconnect flush pipe,remove cistern,remove and adjust filler valve to correct height then refit.


From your photo the top of the filler valve looks to be quite a way from the cistern lid so could perhaps extend.However it is much easier to look the gullible customer straight in the eye and blame the save the planet lot for the poor flush.

What paper are you using?

Some have a lot of air pockets.

We have the eco one piece from Wickes that has low flush volumes(2.9L & 4.5L) and that has no problems.

Just an idea, but a problem I have encountered involves the rubber bung at the back of the pan that the flush pipe from the cistern goes into. It provides a water tight seal. The rubber bung has an inner diameter of around 1 1/2" the flush pipe is 2".

The rubber bung should removed from the pan, pushed fully onto the flush pipe and then the flush pipe/bung inserted into the back of the pan.

The rubber bung stretches to fit snugly around the flush pipe, however if the flush pipe is only partially pushed through the bung, the end of the bung that isn't stretched around the flush pipe, stops a full flush from taking place.

Good luck, I hope this helps.

High level cistern were also a big help in getting rid of the huge floaters on the first flush. Modern close coupled toilets just don't have the flushing power.

We have the same issue, we even had our brand new dual flush (3 and 6 litres) cistern replaced with a 9l one which has not solved the issue. I wonder if it can be affected by the type of pipe used between the two, on our old fashioned toilet we had rigid pipes but now have thinner flexible ones which I did question when the toilet was first replaced but the plumber just said that is the type of pipe used nowadays-does anyone know if this could be the cause of such failure?
