I had to look this up never having heard of it. On the Screwfix website plumbers were saying this is quite popular now but illegal if you are using mains water as the feedback will contaminate it.

I believe it is a power jet so does it not create microscopic bits of poo,aerosolize?

I get that in hot Asia it must be quite pleasant but in winter over hear a cold water jet?

One more point

Boris and Jacob will sort it out Henry, with the help of nanny!

He might not have any petrol but can keep the long queues occupied with keep it uppie!

I have had both plumbers fit them and done it myself. Never heard anyone suggest it's illegal to fit one using mains water, and I cannot see how any contamination could result. It's a spray which carries anything away and not back inside, so that's an illogical idea. We don't worry about washing our hands or scrubbing the spuds, do we, and both are contaminated.

I think you can get a power version (and heated loo seats with a built-in dryer if you are loaded) but most are at standard pressure. I have had them fitted with a mixer valve, so with warm water, but mostly with just cold, which is perfectly OK, refreshing and quite soothing at times. You can regulate the flow to suit your personal preference.
