RE: Re: Interfacing to an Aqualisa digital shower

Tim,

I've installed flow switches on all of my hot water feeds to 4 showers in
the house - I used a 22mm switch with adapters on the 15mm feed pipes -
with absolutely no loss in feed that I can tell. So that may still be an
option??? - plus they're easy to install and fairly cheap.

Paul.
