Hi all, I am looking for more ideas to unclog the black water tank vent.
Diagnoses: Smell after flushing inside. I assumed it was the vent and got a long tip air gun and took the compressor to the boat, hoping to blow out the clog. Before I started blowing I did remove the pump-out lid and I could hear the air rushing in as I unscrewed it, so no working vent.
Removal: Repeatedly tried to blow out the clog with the air gun without success. The air would build up in the hose until I pulled the air gun tip away and then air would flow back out through the vent. I also tried a fishing a wire through the vent and only got about a foot in due to resistance of the bends. The through hull is 90 degrees straight up.
Ideas: This is where I looking for help. First thought is to use a hose to get water in the vent line to soften the clog. I don't expect the water pressure to be better than the air pressure was but if it could soften or loosen possibly. Second idea is to cut the vent hose in the middle remove the clog mechanically and then put the hose together with a barbed coupler. Advantages of this are reasonable working space, both ends of the hose are difficult to get to. Other ideas?
Thanks Tim
