I have been told by the shower people that I need to remove some non
return valves from my thermostatic shower to increase the flow.

Will this help? The pump manual states that there should be no non
return valves present in the inlet pipe to the pump but doesn't mention
anything about the shower itself either way.

This won't help your flow problems!, but is there a non-return valve on
the outlet of the pump or in line with the shower hose? Isn't it a
water bylaw to have one fitted? Or is that just for a
shower-over-the-bath scenario rather than a separate shower cubicle-
although you haven't mentioned what you have?
