Hi my name is ***** ***** I will be happy to assist with this today.In some cases I may need more info to assist better.I apologize for any delay.

I suspect the pressure from the city water connection is slowly allowing water to enter the grey tank due to an internal leak.Did you trace all fresh water lines from all faucets,water inlet and connections etc?

Let me know so we can continue,thanks Pete.
