This is unlikely to be useful, but just in case, I have the main
unit of an Aquadart Hydroflow shower to give away free to anyone who wants
it. This is the type that uses cold water mains pressure to "pull" in
hot water, so as to increase hot water flow in a gravity fed system. No
electric needed. Nowhere near as good as a power shower, but much better
than just a hose straight from the pipes/taps,
However the case and hose were damaged and were discarded before I was
able to get them :(. But if someone can find any use for the unit
(even if just as a spare for their existing) then you're more than
welcome to it.
The e-mail address works.
