Urinal Auto siphon problem

[Dundeeplumber]

Good idea but you may only get the problem on the second flush once water is left in the 'U' of pipework.

I got a hand from come people who held buckets up to where the outlet would be & all seemed fine but I think you're correct as when I first fitted the urinals,they flushed perfectly first time.Its a fair pressure that comes out from the flexis when flushed.

Looks from your picture that the pipework where the hoses are connected are too low unless I'm missing something ...can you post up a picture of one of the urinals...regards Turnpin🙂

Am I right in that water dribbles into the top of the cistern, then when it's full it flushes. I don't seem to have a dribble; how do I adjust the flow?? Been installed for about 5 yrs

Do you have any water?

The most basic type of control is water gets into the cistern by dribbling through either a part closed tap or a on or near the end of the pipe, or a restrictor fitted in the pipe close to th cistern or above it.

Alternately there are many types of water control devices used.
Some still use a restrictor, some allow full flow for short bursts.
One detects the pressure drop in a nearby basin tap, then opens up to let water through.
Or there's a solenoid valve controlled by a timeswitch to stop out of hours waste water.
Or a solenoid controlled by a motion sensor of varying types, some are mains some are battery, althought the battery type usually fail open.
