head tank smell

Postby iceman3500 » June 18th, 2015, 1:37 pm

We have a 1987 3207. I've poured sewage treatment liquid into both tanks after every pump out since we've had it. Lately, there is a god awful sewage smell every time either unit is flushed. It comes from the stern and is even noticeable while under way. The tanks must be vented out the stern but I'm not sure. I've seen in-line filters on various sites and wonder if they work? Does anyone with a 3207 know how the tanks are vented? If there are vent lines, where do they run and what size are they? I've looked through the manual but the information is very generic. Any help is appreciated.

Could be your hoses, especially if original. Thye become impregnated from the inside, and it works its way all the way through the hose.
They make new hose now that allegedly is impervious.

I would concur with Fred with the septic hoses. However, if you google Noflex Digestor, you will see tons of positive hits from many yacht forums where people have used it. I use it all the time and can't say enough about it. It may be all that you need to do....

Where are you buying the Noflex from in Ontario?
We're on Lake Simcoe and frequently pillage and plunder Georgian Bay.

Starport around the corner from you sells it. They also sell one that I am going to start using called Super Enzo from Aqua-Tek. It's supposed to be better than Noflex and I've heard good things about it.
