Installing a Handheld Bidet Spraye

nofoollikeold

1. The risk is that the water supply could be contaminated under certain fault conditions.  For example, a mains leak at a level below the property can cause suction, allowing water to flow back into the mains.  If the "bidet" is not perfectly clean, or contains contaminated water or is accidentally under the surface foul water can enter the mains.  When the supply is restored, that foul water can be redistributed to other users.  
2. Is it likely - no.  
3. If it does happen, the appropriate water authority will trace the source and will prosecute.  
4. We have had clean water in this country for nearly two centuries, largely because of what were water bylaws and are now the water regulations.  Just wanting something against those regulations doesn't make it right to risk the health of others.  
5. I understand you can get WCs which incorporate appropriate and approved controls (basically an air gap to break backward flow).  But they are expensive.

I’ve heard this thing saying that you cannot fit hands in the UK it’s a bit wierd  as it’s far more hygienic. Anyway I don’t think the Water police are gonna find out

It is due to the danger of the dirty water getting back into the water mains supply feeding your and neighbouring properties..  Read and understand the link to WRAS.

They can be fitted if fed via a storage tank of water with suitable air gap.  Do it the correct way and no problems.

Do it wrong and you could end up making you and your neighbours very ill.

The dirty water goes down the toilet you would have to be really stupid to install it incorrectly. It’s pretty straightforward. It’s just like adding a tap. Anyway it’s done now & working fine. 👍

Can you share how it has been installed please?

And  by this you mean "leave your bidet shower head soaking in your toilet". I can't imagine anybody doing that, but yes, there are people that aren't (in their right mind).
And when/if you do this, the pressure in the mains has to drop to negative value. And, IMHO, this isn't much worse than leaving a garden hose gun in a dirty pond or even a shower head in your bathtab with water. I know, there are some regulations preventhing this happening, but typically they are ignored.

Not necessarily, one of the factors that requires consideration is that any debris that comes into contact with the gun can leave bacteria on the surface. Incorrectly installing these products can the allow that bacteria to get back into the drinking water supply. It’s a category 5 fluid risk because pathogenic organisms could end up in water.

Those are almost certainly  illegal to fit in the UK due to the water regs>

Well, that makes it pretty clear, you cannot fit a bum gun to the normal plumbing.

Suggests you can but you need to put something in place to prevent back flow 

Bidets of this type may:

a.  be supplied with cold and/or hot water through Type AA, AB, AD or AUK1 backflow prevention arrangement or type DC device serving the bidet only: or Type AA, AB, AD or AUK1 air gap with or without blended water cistern or type DC backflow prevention device.

That would apply to any hand held shower and indeed to any (old fashioned) bidet. Whereas accidentally dropping the toilet shower head into the water is a practical risk.

Old fashioned bidets generally had an up and over spout which created an air gap between the spill over level of the bidet and the spout so couldn’t be submerged. Showers should also have a hose retaining clip to prevent them reaching the spill over level of a bath or in the case of a bath shower mixer be fitted with a double check valve because the fluid risk is less when used as designed and not as a bidet/douche

Which is exactly why showers have a catch on the side, so that the shower hose is fed through and it can't fall into a bath full of water. 

The regulations are there for a reason, and installing one in contravention because one wants to clean their bum on the cheap is wrong.

We don't live in a shanty town; there are standards for a reason.

As above, showers have a retaining fitting to stop the head dangling into the bath.

Outdoor taps (where you'd generally connect a tap) are fitted with double non-return valves.

Bath mixer taps with showers typically don't, but you can add it if you wish.

Apparently, they aren't good enough, otherwise they would solve the problem with bidet showers.
