Constant Water Usage

[CClassW204]

Hi,

Wondering if anyone can help.

My car was experiencing a water leak back in November. I bought the water outlet, picture below as I was advised this was what was wrong with it. The car seemed fine till around a month ago when it seems to be using a lot of water again. The car doesn't leak water on the floor nor does it appear to be spurting out on the engine somewhere.

Has anyone had the same issue and if so what could it be?
I have now been advised it may be the water pump that is now gone.

If it's the water pump you should see coloured water spewn all over the front where the serpentine belt is .

Coolant leaks out of your water pump when you are on the move. .Or out of the expansion bottle via the seal on a faulty cap

inspect rad carefully . pinhole leaks evaporate in a flash. inspect coolant circuit carefully,

then get coolant analysed for combustion gas
