Grey tank stopped up won't drain
we have always left our grey and black tank valves open as we are full timers [living at a campground 365/24-7] for past 4yrs. This problem of the grey tank getting stopped up only started last month...

Folks, as far as my black tank goes, my toilet dumps right into the elbow leading to my valve, so when I flush it goes directly into the channel first then backed up with water, water, water, and then a build up in the bowl with water then dumped again like a tidal wave coming out of Hoover Dam.
