97 405 Aft Holding Tank Odors/Venting

[ndunlop33]

Thanks so much for all the information! Yes, I understood what you meant. I believe my response was unclear. I have vacu flush on both heads but I did go into the bilge and I also have the overboard pump out macerator. Once again my marina had not emptied my tanks completely. The previous owner had re- piped everything with pvc. I do have the Y valve and there were two valves running parallel coming off the Y valve and both were open. I did turn the valves to the closed position while the pumpout cart was there. I had a friend in the bilge and I watched the tanks while they were being emptied and they were able to pump both out completely and green lights illuminated on both. The aft tank had suction and caught right away and there didn't seem to be any problem. I am hopeful that this fixes my problem! I guess I will find out next weekend if I have 2 green lights on the heads when I return. Once emptied, I did treat both tanks heavily with the Noflex digest and filled both with water until the mid full amber light came on to help clear any build up on the sides. Fingers crossed that turning the valves fixed the suction problem. I will check back in next Thursday when I go back to the boat for the weekend and let you know!

This thread has had quite the transition from the start. Thanks for posting the resolution.

Just wanted to give a quick thanks to everyone for their advice! I believe the problem has solved, your suggestions were right on! Both the venting and the Noflex!

We have a 3207 and are trying to figure out if it has maceration and how to operate it if it has it

I would start a new thread or you're going to get very confusing responses, as some will respond to the OP's issue and some will respond to your.

I doubt you have a macerator, but anything could have happened once the boat left the factory. You might want to post up some pics (in the new thread) of your heads and your black water tank and hoses and you might get some good responses.
