The tank I thought was the gray water is in fact the fresh water. So I think I have a bit of a job on my handsTank helpI'm new and I've just bought a motorhome. I'm finding some issues with it as far as the tanks and water leaking. This tank is located under the kitchen sink and is hooked to the gray water tank and the water pump. It is split down the side and unable to hold water, what is this tank used for and how can I replace it? Do I have to find another aluminum tank or will plastic do?
