Quick plumbing Q. Most of cold water plumbing in my house operates
at mains water pressure. There is a cold tank, but as far as I've been
able to work out, the only things supplied from it ar e the hot water
cylinder and the bidet (?!). This is as a result of several mods and
extension by the previous owner. There was also a water softener which
is now bypassed.
It all works fine and I've no intension of changing anything unless I
have to. However, since i'm refitting the laundry room (where the mains
water access point is), is there anything I need to check to satisfy
The reason you're referring to is presumably to prevent contamination
of the mains supply by back syphoning of yucky water from the bidet?
If so, then it depends on the bidet... ours is only fillable from a
conventional tap arrangement and doesn't have the botty-fountain bit
(therefore it is functionally no different to a bath or basin). I've
never thought about it before - not being a bidet fan personally! -
but presumably the reason this would have been installed in our house
is because we have only mains water (ie no cold tank at all).
I never understood this idea that you could plumb a bidet without the
fountain bit. It somewhat defeats the point. It would be like saying you
were allowed shower cubicles as long as you only have low down taps and no
shower head. Talk about chocolate teapots.
A bidet is very different to a shower cubicle. A bidet with a fountain can
be fitted with a dedicated pipe to the cold water tank in the loft. In
short it will not contaminate anything in the pipework.

Like I said, I'm not a bidet fan at all and prefer a shower to deal
with the hygiene of my nether regions. Nevertheless, I disagree with
your "shower with no showerhead / chocolate teapot" analogy... when
did anyone ever say that bidets have to have fountains? It's not like
ours doesn't have the fountain plumbed in, simply that the bidet
doesn't have one built in. Some do some don't. Ours is designed
either to be filled with warm water, then you sit astride it and
dangle your bits in the water, like a wash basin; or you can sit
facing the directable mixer tap and aim the water jet where you want
it. Doesn't point directly at your orifices like a fountain would of
course, but then neither does a normal fixed shower head in a shower,
and that works OK for most folk!
