Hi
I have a thermostatic over bath shower / bath mixer tap. To divert to shower you pull up a knob and it should remain up while showering.. But it continually falls back to the bath position while showering.
We have H&C water both at mains pressure as the house uses a Megaflow HW tank and mains pressure cold water to all taps.
The only thing that reduces pressure is a Harvey's water softener but the pressure reduction is minimal.
A peg won't hold the knob up in the shower position as its too little lift to allow the divert to occur.
Can the divertor be replaced or altered to allow it to remain up? Or are there, and as a last resort, thermostatic bath shower taps that don't use the pop up diverter method at a reasonable cost?
This is an example the type of tap
