The grey water tank will not drain and I believe it is very full. 99% certain the trap is open as I have pulled off the cover and pulled the metal rod attached to the trap. I believe there is a blockage. Question is... how do I get to it to make it move? Too far and too many 90s to get it directly. Can I drill a hole in the waste pipe after the trap and then snake it? Or have I totally missed an easier option.
This is a 2021 Jayco North Point 377.
Depending on where you are I would search for a company that cleans RV tanks. They know how to get rid of the blockage despite the number of els.. Or call you dealer to see they have someone to recommend.
This works on black tanks but maybe can be modded to work on gray tank by disconnecting the hose from the sewer dump, then filling it with water while holding it up high?
