Thanks linda s, I will see if I can make sure that the kitchen sink is not the culprit. What about the bathroom sink, and shower, do they not go into grey tank as well? It seems to fill it up quicker than the drip drip from the kitchen sink, but I will look into that and stop that drip, along with the bathroom sink. I notice dripping coming from above the actual grey tank. I have a guest staying in the rv currently, when he leaves I will attempt to drop the grey tank and see where that dripping is coming from. No drips when city water is off. Currently just turning city water off when there is no need for water for washing, and turn on when they need to take a shower or do dishes and stuff. Thanks again to you for the reply.
