Bidet hot water installation

That uses both hot and cold supplies. It must be fed by a category 5 compliant cistern (break tank) and hot water system both that are unique to the douche. There are other ways, pipe interrupters, etc

The cold can be made compliant by using a cistern with air gap and weir overflow, the hot is harder unless you can feed it with a CAT5 protected hw supply (a hot water cylinder that is fed from a CAT5 compliant cold water cistern that nothing else uses, it can't be from a shared HW cylinder or from a combi.

To make it compliant wouldn't be cheap.

A woman friend decided to start a dog grooming business and wanted a shower fitted for washing the dogs, she was getting quotes of between £25K and £30K, had to be done properly as she needed a licence from the council, in the end she didnt bother and just trims them , lots around here doing the bathing thing illegally, but the fines are huge if caught

I'd just use double check valves on hot and cold. WRAS is completely absurd on this one and not in line with best practice in the rest of the world.

It's still not compliant and the person can ask be asked to remove it if it isn't and be fined for the pleasure.

WRAS is completely absurd on this one .... in your view.

It's in legislation for a reason. I wouldn't want any risk of faecal bacteria from contaminated water getting anywhere my drinking water thanks but this argument has been done to death. It's illegal in many countries (US/AU/etc) to connect these devices to the mains for that exact reason, certainly not best practice.

It's the law and that's that, anyone installing these ablution/douche items without proper procedures isn't being a professional.

And in doing so you'd be in breach of the regulations and liable for a large fine if the water supply became contaminated. The regs are there for a very good reason, not to be ignored because they're inconvenient

Hi guys

I want to fit one of these bad boys:

My understanding is that these can't be plumbed directly into the hot water feed. The system must be isolated due to the risk of backflow.

I would be grateful if somebody could give me more details on how this can be installed in a compliant way.

Kind regards

What's your hot water setup? Conventional boiler and low pressure cylinder? Unvented cylinder? Combi boiler?
