I've a downstairs shower in a room with a gravity-fed hot and mains cold. The electric shower has given up the ghost, and I always thought that the only alternative was a venturi; but I see that Screwfix have what they call a "Pressure Balancing Mixer Shower" (see
formatting link
for the Screwfix page) which can handle pressures from 0.5 to 5 bar (main here is about 2.5-3). Would that be appropriate for this shower, and what performance can I expect? I should say that I'd like a shower which can provide pure cold at reasonable pressure as well as a hot shower (at present I have the former only:-).
Grateful for advice.
