Toilet syphon ?

[secret squirrel]

I repaired a toilet, job turned into a nightmare, bolts holding the cistern were rusted through, no iso valve etc took an age to sort out.

The problem was the donut washer was leaking and I replaced the syphon because I had no choice, I had damaged it to get the bolts off etc.

Anyway, I replaced it with an Opella Wras approved etc. Whilst there I also replaced the inlet valve with a fluid master. The toilet is about 15 years old and has seen an awful lot of use.

The only thing not replaced was the handle.

The problem is although it flushes it is not perfect, this is the 2nd time this has happened with older toilets.

On both occasions the customer has been happy but I'm not, the handles seem to be a little loose and I can't tighten them.

There are no leaks and is installed correctly, Is the problem the syphon itself? do I need to use a more expensive part? does the age of the toilet have any bearing on the flush? Are the handles an issue?

It cold be that the siphon you put in is slightly higher to the invert which would make it a little harder to flush .. from memory should be about 28mm above the water level .. don't quote me!! anyway try a higher water level if you can.

Pretty sure mate its all part of the water regs its irrelevant what the cistern will hold litre wise, its what the syphon is able to deliver.

It is the quality of the syphon ...the opella ones that are £4 just do not cut the mustard.they also do one for about £6 (the black one )and they are much better. The handles on old cisterns are also a different size and are always a little loose.

I've found that the length of the C link on the new syphon can affect how well it flushes in an older cistern. I think it's due to the body section on the newer syphons being lower so the link isn't generally long enough. I carry a selection of different length C links and tend swap them to get a better flush

The "C" links can be made to the exact size by using a brass welding rod

The plastic displacer washers can be cut from an old plastic fertiliser bag, or any heavy duty plastic sheet
