Installing smart toilet/bidet seat ?

[TonyR1]

I see a lot of Japanese smart toliet seats around with a bidet spray built into them and thinking of getting one. Only question is what is needed to connect them to a water supply. I am imagining a direct connection is not allowed because of the backflow risk from the jet nozzle and I don’t want to go back to having a header tank just for it (especially as they seem to need a minimum 1 bar water pressure. So what do people do in practice? Thanks

Header tank, single shower pump, under sink water heater and a tmv3

Thanks Shaun but not that type of bidet. I mean more of the type linked below where the water heater etc are all built in so no need for a water heater and tmv3. And a header tank is OTT - have just got rid of them all recently and don’t want to go back there.

There no way around it as it’s a cat 5 risk you need a break tank and pump as it requires a min pressure

I shudder to think of how many of these there are that are connected to the mains.

Bummer. There must be loads of these seats around that are DIY plumbed straight in, especially in flats where there is no opportunity for a header tank. Just wondering if you could run a pump off a bigger cistern or if there are pressurised break tanks available to give the 1 bar minimum pressure. Even a standard header tank installation is unlikely to achieve that.
