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.

change the syphon its probably pin holed

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

if it keeps dripping there is

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-HybridHeat]

Yeh the urinals are constantly dripping

think he means its dripping into the :nono: pot

 

[townfanjon]

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

If its dripping steadily from the petcock into the cistern, and flushing periodically, its working exactly as designed.

If its dripping steadily from the urinal spreaders, then its the auto-syphon thats gone.

If its dripping from anywhere else - somethings leaking!

or someones missed

Start again ...... If the pet cock is letting a small steady flow of water into the cistern and the auto syphon is at its flush level , it will leak the same amount back into the urinal . Or have I had toooooo much jack daniels lol.

Put a new pet cock on or iso valve in the morning it wont do any harm to pull out the syphon out and clean it and give it a go.

Hopefully nobody has chucked anything in the cistern .

Did find a suspicious looking bag on top of it, definitely won't be putting my hands in without looking...

Yep be carefull thats why a lot of them are screwed down with types of torx or star type set screws.

Pet cock is adjustable ..although under regs you are supposed to fit water saving device I.e cistermiser to save water...although a complete overhaul would not go a miss ....auto syphon sized according to size of cistern and amount of urinal's known as range of ...1 ..2..3.etc...regards Turnpin:smile5:

if itis filling as fast as its emptying it will constantly flush if it flushes and stops but still drips water must be passing into the syphon tube
