3 Ways to Prevent a Plugged Black Water Holding Tank

As anyone who has experienced a plugged tank will attest, it is not fun and can be extremely difficult to clear without making a big mess!

To prevent you from ever having to experience this unfortunate situation (or other black holding tank issues) you will need to remember 3 key things.

1. Use lots of water!

People don’t seem to realize that they should use more water than the volume of water used during the flush cycle. A good rule of thumb is to fill the bowl a second time and dump it, to insure you are using enough water. This is just one way to avoid a plugged tank.

Sounds a little bizarre but you have a couple of choices. Boat owners have always had a waste basket beside the toilet and they fold the paper after use and put it in the basket. Their motto is, if it has not been in your mouth it does not go in the toilet. A second way to do this is much more appealing (at least to me).  Add a bidet to your toilet. We carry such a device called the Biffy. This eliminates any possibility of odors, and is actually better for you. The toilet paper is used simply as a drying device, cutting the volume of toilet paper in your holding tanks dramatically.

3. Keep an eye on the Grandkids.

It turns out that kids seem to like putting toys, or cats, where they do not belong. I can’t think of a less desirable find than a fuzzy cat as the culprit of a plugged tank!cat in toilet

The other, more common than you would think, culprit that you have no control over, is the RV manufacturer leaving plastic plugs from the hole saw, used to penetrate the tank for input plumbing from the sinks, shower etc., and of course the roof vent which goes on both the black and gray water tanks. This is an example of a hole saw plug.

As always, common sense applies when using your RV and if it doesn’t feel good it probably needs investigating.
