Thermostatic electric shower cutting out due to low pressure

[JTplumbingservices]

So I was asked to go look at a job today I was told 3 plumbers have been at previously with the same issue still occurring.
Shower is cutting out completely with the low pressure light on when the basin or sink tap is turned on.
I’ve managed to have them all working together by shutting down the ballofix valves on each tap but this isn’t ideal as pressure wasn’t great to start with.
I can’t see how it’s piped as it’s all done behind the walls.
All I can think is with the pressure not being amazing to begin with maybe the shower is the last connection on the run and opening something before it is leaving very little water to reach it.
Last 3 plumbers have fitted new showers.
Thoughts guys ?
Cheers

ALL electric showers with a integral pump are designed to be gravity (tank) fed.
They are usually installed where mains pressure is poor, a mains supplied electric shower requires ~ a sustained 0.8/1.0 bar at 8 LPM.
You could possibly/probably run it on mains if the pressure was reduced to ~ 0.5/1.0 bar via a PRV but this is not recommended.
Most, if not all "care" type showers will be tank fed because any temporary interruption in the mains pressure will not immediately affect the shower performance.

Safeguard Care Pumped Thermostatic Shower

The Safeguard Care Pumped is ideal for low water pressure areas. Designed specifically for use with a gravity fed cold water supply from a header tank, the integrated pump boosts the flow rate of your shower. The Safeguard Care Pumped is perfect for those who require additional showering aids...

I don’t knew why but I’m just getting notifications for this now.
I don’t know why you think it’s a pumped shower and tank fed?
It’s mains fed and not pumped.

I know, that’s why I said I don’t know why I’m getting them now.
