Upside down cistern fill valve..

[RayPlumb]

On a job today and asked to change the WC cistern, supplied by customer from a supposedly 'better' online bathroom supplier.
The instructions looked a bit suspect as if translated direct from Chinese.. Anyone seen one of these before??
The inlet valve(pictured). No it is not upside down.. The shut off valve is actually at the bottom thus totally submerged under the water. Suspecting 😱 this did not comply with the air gap I refused to fit. And changed the fitting for wras approved ones.
How are these big companies allowed to sell these.

Big companies are allowed to sell them because if you install them with a double check valve then they're fine to fit.

So would this get WRAS approval.

No would need extras to be installed

Learn something new every day. I thought if they did not have wras approval we could not fit.

Extras other than a double check valve?

Some Wras approved products still need installation requirement notes (IRNs). Eg an inlet valve can be wras approved and yet needs a double check valve as it doesn’t meet the back flow requirements, but it does meet the materials in contact with water requirements and can therefore be wras approved.

could not find any wras approved indication. Just a bit on the bottom ''Producting of china top standard'' ..did not convince me of quality 😵

I am with you Bin it and fit wraps approved inlet valve. Kop

I can't see the Chineese valve lasting long before it fails, you're better off without it.

On the subject of bottom entry inlet valves, I recall someone on the forums fairly recently posting an advisory they had (from where I cannot remember, maybe the water supplier?) been sent in writing that even the "top notch" fluidmaster pro valves now need a double check valve installed on the supply. They were getting reports of blue water in the mains supply caused by blue cistern blocks (blocks of the devil) and water back flowing into the mains and dying the water blue.

Does anyone else remember this?

Really Shaun??? WRAS appro can come with caveats. RP01 etc. It is up to the installer to satisfy that they comply with the approval details.

On good valves there is a line (can't remember its name HELP!) where you must install so this is 25mm (if mem serves) above the fill line. As so few people did it, or even knew of its existence, I suspect this is to 'replace' or supplement that.

Yea so it would be approved / comply without extras being installed

Sorry. Confused. WRAS approval may be granted even though it requires additional/supplementary work in order to comply such as double check valves (R160).

Take the B24011 NABIS & B24007 NABIS. Each of these require a double check valve to comply with their WRAS approval (#1407087), YET neither is supplied with one.

Yes so install one without it it doesn’t comply / have wraps approval as the bits required for wras approval arnt fitted

Mr Ray, why you no fit our walve? Very good walve Mr Ray!

I love Chinglish, it’s an amazing place to work if you ever get the chance. They’d much rather you bribed them to say whatever you’re there to fix is fixed than actually fix the thing in my experience.
