triton bezique goes cold indicating low pressure during use?

your filter is located in the end of the mains pipe where it joins the shower.
isolate the water and remove the main pipe.

also check your flow turn to fully hot then turn to fully cold
is the flow alot faster on the cold setting ?

also check if your solinoid has 3.5 ohms.
if less than 3.5 your soliniold valve is faulty.

if your flow is no different from hot to cold your flow stabilizer is faulty.
