Sewer Smell when using furnace and blower

Dear Techies: I have a recent issue with my 1996 Fleetwood bounder 34H....after swapping to a different toilet a nasty smell is upon me as I run the furnace. The foul stink smells like sewer.... I am miffed as to how to track it down. The vent pipes are not up in my face where I can see how they attach to the black water tank. Any thoughts on where i might get started?

Depending on the toilet you might hae to extend the toilet vent on top of the unit. There are several new vent systems you could try. Camping World would be a place to start

Your leaking toilet seal could have caused waste to leak in and around tanks. Repair the seal, then see if you can spray and clean around the tanks if needed. I would guess that if you have enclosed tanks, the furnace vent in that area to keep things heated is blowing the smell back up into the coach.

I will be working on the seal replacement upon arrival home will see if the thetford foam replacement will hold up to install. These foam flange gaskets are very brittle.

I replaced the Thetford flange gasket seal and am assured that it is properly in place. I am still smelling a sewer stink in my MH as the blower kicks in from the furnace. Anyone have a diagram of the plumbing layout for a 1996 34H.... I would love to inspect the vent pipe in this rig.

If you have agood seal on the toilet, and cant find anything leaking, maybe check our furnace for a propane leak, it smells bad like rotten eggs, maybe a bit like poop smell.

Also, an absolute long shot, batteries outgassing from overcharging will smell kinda like holding tank odor.

George...that is a good thought... in my arrangement the batteries are not stored in the compartments but rather right up front in the radiator and fluid area. The odor of batteries in this model could not give you that wonderful leaking stinky.

Does it smell in the dump compartment? Perhaps your leaking toilet allowed waste to collect on TOP of the tank or in the compartment. Do you have enclosed, heated tanks? Also, dump and clean tanks, see if it smells after that.

There is no smell in the dump compartment....and that is an excellent question. I had dumped and cleaned the tank a week ago. It was fairly full.... and we added some tank deodorant. I thought I should be smelling something better than a sewer gas. I can not see any indications of a leak where raw sewage might be in my undercarriage..... but again...I can not get my face up and around the top tank area. All the mayhem started when I swapped toilets with the older model. Now that I have returned to the original toilet and can verify the good flange seal I was thinking the smell should be going away.

Is it possible that something made its way into your heating system, either the return or the duct work? Maybe shut the system down and do a sniff test at every vents and intake to try and isolate the source?? could even be a dead animal.

Inside a cabinet or behind drawers, where there is no direct black or gray vent thru the roof, you will no doubt find 1-1/4 inch ABS pipe and a funny looking cap with a spring and rubber disc. It is a Air Advancement Valve, I think, and it lets air in when water is running in a sink, shower, etc. and closes off when water stops. Maybe you have one of these that is stuck in the open position.

We did...... PU....... Replaced it and all is well.
