Folks

Thanks for the advice so far.

To clarify: the shower does not do any heating of the water itself. It just
mixes the existing hot & cold water supplies. The only controls are a
thermostatic dial and an Off-On-Boost flow control knob. It's an Aqualisa, I
think the Aquastream, as pictured & described he

The water feeds are into the rear of the unit so I'm not sure if I can do
anything about adjusting the water pressure without dismantling the whole thing.
