Our cardinal smelled terrible, we found out that the laundry hookup that we never used was wide open. since you never put water down it the trap was never full, we put a clamp on rubber pipe cap on it and VIOLA....odor gone

Thks for info regarding laundry hookup--will check that. Wonder if your smell was specific to toilet area? Would think laundry would drain in gray tanks, not black. Again, thks-worth checking everything.

Smell was hard to locate for us, one time smelled over here..then over there! Does your toilet hold water ? if it leaks by the seal then air will also come up. We try to keep a little water in the toilet to help seal the seal ,

OK, so if vent was installed too far into the tank, any suggestions on how a common person with limited tools can fix this? We did not have great faith in our dealer at the time and if this is labor intensive (which probably is) you can bet it was ignored and now the cost is ours. And no--we typically use the fantastic fan for forcing shower humidity out but not for encouraging toilet odors up.

OK-as original post msg perhaps I should have been more clear. Based on past experience, either with other RV's and/or 30+ years of household septic use, we have never had this issue. We understand not to use a fantastic fan to draw air up out of the toilet, we use the correct dissolvable toilet tissue, use the correct toilet treatment, the shower is not draining in the black tank, etc. Appreciate the tip on how to use a garden hose to check for a clogged vent pipe. If the vent pipe was installed too deep in the black tank (which seems likely at this point) does anyone know the easiest/best way to correct it? This Cardinal has metal underpinning and we understand getting to the black tank is not an easy feat. If this is something that is best handled by a RV dealer who would have the proper tools, perhaps we'll bite the bullet and pay for it...or continue as we have from day 1 and empty the tank at half full. And no, we don't continue to add water to make it at least 2/3 full before dumping--your nose & eyes wouldn't be able to stand it. We are full-timers and make it a point to thoroughly flush our tanks every 4 weeks, if not sooner.

If it is the vent being to low, one way to check is to measure from the top down.(with an empty tank slide a tape all the way down to tank bottom take this measure ment, then bring the tape up to hook on the vent pipe and take that measurement, lastly you need to determine how deep the actualt tank is, this may be able to be accomplished from under the unit) if the vent appears to be over 2 inches into the tank then yes it is to far in. There are three ways to change this, one drop the tank and cut the pipe (very difficult) Two undo the vent cap on the top - apply two sets of visegrips (to hold the pipe and give leverage) and lift the pipe up and cut, then reapply the vent cap and seal properly - third locate the vent interior and if accessable cut the pipe and place a lift the vent pipe and place a coupling (would prefere a nohub coupling myself) and close it up.

In any way not an easy fix but can be done. Best of luck.

To check if vent length is in fact the issue, you can try the following, won't be pleasant, but will prove a problem before spending a bunch of cash on a repair that may not solve your problem.

1. Empty black water tank.
2. Turn off water feed or water pump.
3. Use a mechanics mirror with long handle and flashlight to look in the tank through the toilet opening.

If the vent pipe is actually that much longer, it should be easily spotted using mirror. If that is not the problem, then you've saved yourself money. If it is the problem then have it fixed by a qualified RV mechanic.

The "look down the toilet" method will not work in my camper. It has 2 45 degree bends in it before it drops into the black tank.

While there is a case here on the forum that the black vent had slipped into the black tank before the cement dried, IMO it would be rare indeed.

I would be concentrating my efforts on the gray tank odors. A really bad smell in the kitchen turned out to be a damp dishrag tossed into the cabinet under the sink. Forgotten about for a month between trips, it took a week of troubleshooting to find the source of that awful smell.

Another way to check, if you can't see in, is to have someone stay on the roof listening in the vent. Fill the tank, through the toilet with a garden hose. If they stop hearing incoming water before the tank fills, then the vent is too low in the tank. Once the afffluent covers the bottom of the venp pipe, the vent stops working, and the air becomes displaced out the toilet.

As it is, air dispacement when flushing is "easier" through the open toilet flap than through the vent. The flush opening is about 2-3" (I've never actually measured, just guesstamating) and the vent is only 1.5". Air will take the path of least resistance, and if the vent fan is on, the fan helps it!
