Side Entry Ball Valves (2 of 2)

So backflow was the only reason this guy gave to say they were illegal? I think, by law, he is correct BUT if a dcv is fitted someone who isn't so anal can pass it without it breaking the law.

Yes and no he said they didn't have a bs no so they shouldn't be used and also back flow could happen but tbh I think it's one of them 10000000000000/1 situations don't see how it could back flow on mains with 3 bar behind it fair enough on tank but mains lol

The only problem with the regs. Is its all on interpretation you might read it one way and say its correct where as I might say that it's wrong although we could both be right

I think ill stick to buying part 2 valves from now just to be on the safe side,

Ray might see a drop in sales of part 1 valves after this thread

Ohhh ok, so basically they've used cheapo valves that aren't BS approved.. If theyd been BS approved I bet he'd have passed them

But I would think they would be bs approved as everything sold is might not have the bs stamp don't know will pull one out and inspect it will thro some pics up when I do,

And yes plumb nothing is ever down in black it's all down to the installer to interprete the rules

A tank is a receptacle for storing water and an air gap is what it says.
Neither know if their purpose is to flush a WC , feed a DHW cylinder or act as F&E.
Can anyone explain why a ball valve deemed safe for the latter two is unsafe on a WC cistern.
As for bending the arm, I have yet to break one but often ripple a copper tube. If this logic continues the commercial interests that sell us fittings will persuade the regulators that bending tube should be banned.

I admit I once snapped a part 1 ball valve arm when giving it a bend.
But it was the standard cheap valve and the "brass" arm was hard & brittle rubbish.
I was very lucky to not get ripped open with it, as the broken ends were long jagged shards.

Give it a lick with the blow lamp before bending always helps I find
