The dreaded "tank problem"s.... I am having trouble with both my gray tank and my black tank. 1) My gray tank is continuously clogged. I have to take a plunger to it about once a month to empty...
I am guessing you have this in a permanent site and cannot move it.. My only suggestion is RIDX for RV's and use according to directions. The white stuff concerns me as if it is grease then maybe a different disposal method for the grease should be found
