waste tank stink in head

[geoffm70]

leave the boat for a couple days with water in the toilet bowl, comeback and the water is urine yellow and the smell is unbearable. i've emptied the waste tank and put biologic treatment in + keep putting that in the bowl with water. been 2 weeks now and still stinks. apparently, my son saw bubbles coming into the toilet bowl water followed by minor smell the other day. have a newer (3yrs old) Jabsco pump toilet and leave the fill or empty switch on empty.

What kind of system do you have, vacuflush or electric Macerator? That’s probably a sign the your vent hose or filter is plugged and the joker valve (if electric Macerator) is bad. As the tank heats up it could be pushing its contents back to the bowl.

thanks, going to try the venting, but I two, yesterday, witnessed stink bubbles back into the bowl?!
