How do you stop a shower from pouring out of the overflow pipe?

Question

i have a triton miami shower, its started pouring water out the overflow pipe when i try to use it.

does anyone know why its doing it and how to fix it??????

Answer 1

Probably clogged, try some CLS.  

Answer 2

your prv has activated. (pressure relief valve) If yours has one.

Most times a pressure problem or blockage causes this, is caused by a blocked shower head or screen from scale - collected deposits or  debris within the water lines.

Is the flex pipe twisted?
