Forget monsters under the bed, is it possible for
live animals to come out of your toilet? While the
idea of snakes lurking in your bowl while you are
at your most vulnerable may be a scary thought,
it may not be that far from the truth. Pest control
companies around the country have reported on
finding and removing snakes from toilets periodically.
How do they get through the porcelain gate?
A typical home has multiple stack pipes running from the sewer through the roof that vent sewer gases. These connect to the home’s drain system which empties water used by the dishwasher, in showers and when flushing toilets. But for much of the time, the pipes remain dry. A creature on the roof, say a squirrel, or a rat in a sewer — more prevalent in older, larger, cavernous systems — can scamper up or down the pipe. A wrong turn, a quick dunk in the short, S-shaped goose neck pipe and it’s, Hello, john or John!
An additional avenue for the snake to enter the toilet is directly through the plumbing pipes underneath a home. If a home has a crawl space underneath the first floor, and there is a hole in the one of the pipes, the snake can enter at this spot and find its way up into the toilet drain.
1. Stay calm!
2. Keep the lid down.
3. Squirt liquid dish soap into the toilet. This breaks the surface tension of the water, according to health department officials.
4. Flush. Maybe two or three times, if you have a really persistent rat.
If animal visits are recurring, you can cover the top of the vent pipe with something like chicken wire, just to keep critters from falling in. You want a material with fine wires and fairly large holes; don’t use screen or even fine hardware cloth, which can become clogged with dirt or snow and block off the vent; very bad. Whatever cover you try, make sure to check it periodically to confirm the vent is “breathing” as normal.
To stop rats and snakes from entering through the sewer system, find out where your house’s main drain runs along your property, and look for burrows in the area; these could link up to holes in the drain pipe. You can also have a plumber scope the drain with a video camera and/or ask the city to scope their line to look for possible entry points.
Don't call a plumber if you do happen to find a critter, we don't deal with those types of clogs!
