Air bubbles when flushing

[G8orwayne]

We have two bathrooms in our Big Country and 1 of them has recently started shooting air bubbles out when flushing. I have flushed the system to make sure no excess gas has accumulated but still have the issue. Any thoughts?

That usually means your vent pipe is blocked somehow. Hopefully someone with experience can tell you what can be done to check that and solve any issues.

Bubbles or burping is a sign that the black tank is full. Do you have 2 black tanks? Are you sure the tanks are empty?

Yes we have two black tanks and I am sure they are empty.

Do you mean air bubbles coming out with the water when you flush? Don’t think you would see air bubbles from black tank. That would be more like a burst of air if there is a vent problem.

As TravelTiger said, you probably have some type of blockage. Start by checking the vents on the roof. If you don't see anything odd there, you may have an obstruction in the vertical (or near vertical) drain under the toilet.

Poop pyramid under that particular toilet?

Lynn is probably right on. We have been traveling in our BH 3875FB for a couple.months and had a similar issue with the master bath commode.

That particular commode has a sewer pipe with an offset. I started to notice it burping. I snaked it, and eventually determined that we were not using adequate water volumes to flush which allows the issue that Lynn suggests.

Haven't had issues since increasing water volume per flush.
