Just moved in to the new house, and, as per title, there is a Triton T80xr Shower unit. There seems plenty of water pressure, but the "Low Pressure" warning is permanently lit and the water permanently cold. I first turned it on not realising that it was controlled by a different stopcock to the main house, so I suspect it needs some sort of internal reset. I've tried switching it off by the isolator switch outside the room, but no change.
Any ideas?
PS: If it should prove relevant, currently connecting via tethered mobile with fringe reception - very, very slow.
