DIYbanter - View Single Post - want a toilet cistern that fills underwater

wrote:
I'm about to replace my toilet. The old cistern (Italian, expensive,
20 years old) had a little tube inside that meant it refilled
underwater, rather than pouring water into the tank as most toilets do.
**Much** quieter.

None of the toilets I've looked at recently seem to have this feature.
Do they still exist, or have they been banned by building regs etc?
Does anyone know where I can get one?

Many thanks,

Chris

My latest from Bathstore does precisely that.

Although the little tube is simply a long polythene bag clamped over the
end
It also has a flow restrict or in it to limit the flow rate. Its very
quiet, and built with all the lack of ruggedness that only 3 decades of
marketing can bring to the design process.
