Has anyone heard of a "symphonic" valve in connection with toilet cisterns?

Question

Have a toilet that the water climbs too high in the pan when flushed. Have been told by plumber that I need a symphonic valve replaced in the cistern. He also says the toilet has a double U-bend. Could all this be true? And how do these symphonic valves work?

Answer 1

barry be is spot on

I dont think the plumber is a dumbo more of a con artist

Answer 2

It is far more likely that you have a partial blockage in your toilet.  Try a plunger first.  I cannot see how changing the valve would make any difference.

Answer 3

The word is SYPHONIC. It is a valve that syphons the water from the toilet bowl.

Answer 4

As Barry B says, your "plumber" is either as thick as two short planks or he's trying it on. The syphonic system is just the double-bend trap, you have a partial blockage.  A plunger might shift it, or if you don't have one a mop with the head wrapped in a bin liner to keep it clean will do just as well.

Answer 5

It's a syphonic valve ..................  

Answer 6

Your 'plumber' is a dumbo. It is nothing to do with the cistern. I lived in a house with a siphonic wc for many years. It is a double trap. The majority of the water when flushed goes into the second trap creating a siphon which sucks out the contents of the bowl. The bowl then refills to the correct level at the end of the procedure. There is no 'valve' the action is automatic and needs no maintenance other than to ensure that there are no blockages. A good chemical toilet unblocker left over night will probably do the trick. A plunger may be needed for a stubborn blockage.
