Can i use a ball lever as mains stopcock

[chris watkins]

The question regards a plumbing valve with 'stop' incorporated.
From my experience 'Stop' means - non return valve.
A valve with a loose washer, that will seal 'techinally' to prevent backflow.
Most of our water meter valves are 1/4 turn, hence the requirement for a dual check backflow valve.
This is to prevent the water from a property entering the mains, if the mains are switched off for any reason.
Not sure what Cat 3 & Cat 5 are.

OZ, can I humbly suggest that as a practising Plumber (if in the UK), you book yourself onto a Water Regulation training course asap.
As you maybe confusing others seeking info on back flow issue.

Unless the full link isnt working and there’s something else , it says Yes !!
I would love to see the waterboard tell some of my customers their lever arm is coming out !!
I have spent years telling and training them to turn off their water when they go away , they love em and use them because its easy . Go back to stop taps and they wouldn’t bother lol .
