Trying to figure out where the toilet vents on the 3000scr. No smells in cabin but smells outside of boat when you flush. Does anyone know if there is some kind of a filter? It's a jabsco 29090.
No filter is standard but you can add one to the holding tank vent line, some folks asplso use an addictive to reduce the smell. RV and marine stores carry both.
The vent line is port side forward of the generator. RV tank treatments are woefully inadequate. The only stuff that truly works is rtb780. Www.microbialogic.com
You should absolutely be using marine/rv holding tank chemicals. This is more about breaking solids down into liquids. Get regular pumpout, and don't let contents sit in the holding tank for more than 5 days. However, what you're dealing with is the displacement of air from the holding tank when you push black water into the tank.
The only way to fix this properly is a holding tank vent filter. This needs to be replaced seasonally.
