Found water leakage on my shower. Let's fix it.
First of all, I pull of my shower head and hose for convenience.
There are 2 hexagonal bolts connected by body and supply lines.
Remember where o-rings are mounted.
Separate shower hose connector and I can see another flat blue colored o-ring.
Next step is take out another outlet part to clean filter in it. (Not an essential job)
Let's take out handle with
Unscrew handle screw and unwind body kit to take out handle.
Separated into 2 parts
Let's see whats inside.
Seems like blue gasket prevent leakage and 3 holes manage water temperature.
More details of principals
This is how washbasin control outlet water temperature
Let's back again with body kit assembly
And lever. much faster and easier than disassembly.
But..............
Have no idea where leakage came from :(
