Overflowing urinal cistern

[Dan-HybridHeat]

Been asked to look at a urinal cistern that is constantly dripping - never dealt with them before. As far as I was aware they were on timed electronic devices that released every so often.

I've come across this which is constantly passing and causing the urinals to drip constantly, any ideas what it is/how it works? At some points the cistern still does a full flush as it should.

have a look at cistermiser

and tbh thats normally and very doubt full there a solenoid inline and while your there replace the auto flush theres two types (different heights)

 

[Dan-HybridHeat]

No cistermiser, literally a CW pipe coming through the loft and into that valve. Will change the siphon, any idea what that valve's called?

The valve on the end is a pet cock, either put a new one on or just put an isolation valve and drip the water into the cistern , time it for a flush every 15/20 mins

No I think the cistern is permanently filling

yea but it shouldnt drip while filling maybe be wrong but thats how i read it

Lol , the pic shows a steady slow flow of water , so it will make the syphon flush , ( its been a long day and I am on the Jack Daniels , dont make me work so hard lol )

Dan, is the flow from the pet cock as steady as it looks on the pic ?

Yes mate, I'm guessing that's flowing more than it should. But like shaun said there's a constant drip into the :nono: as well
