Hi, I have a 2020 32 gk. We have been parked in the same location and Hooked up to the same water source the whole time (2 months). About a month ago I noticed the water is yellow sometimes. Then I noticed it turns yellow after flushing the toilet. So the sinks and showers have clear water, then flush and they turn yellow for about 3 seconds, then clear again. Water in toilet is always kinda yellow. Any ideas? The water source is a filtered well and we have another filter on the hose. I think it is internal, but not sure where to go from there. Help please.
