Many people frequently have house sewer line or drain issues that get exasperated because they cannot find the sewer trap uncover their house drain. These issues can range from needing the drain cleaned to foul sewer smells and basement flooding.
There is a simple process to find the sewer trap and expose it before drain issues arise. This is something every home owner should take a few minutes to do before they are in a distressful situation.
The easiest way to find the sewer trap is to locate the fresh air inlet pipe which is typically located near the front wall of your house. On the outside front or side of your house it will be exposed and covered by a grating.
The grating on the fresh air inlet is usually around 9″ or 10″ wide and perforated in order to allow air to enter the system. In some cases the fresh air inlet for the house sewer will be a U shaped pipe pointing down at the sidewalk.
The fresh air inlet pipe itself is typically at least 3″ wide or 1/2 the size of the house drain, whichever is greater. Once you locate the fresh air inlet pipe inside your house you should be able to find the sewer trap on the street side of the inlet . It is illegal to have plumbing fixtures connected to a fresh air inlet although on occasion a house sewer may have such a connection.
Another important reason the access pit must be accessible is that frequently the water service line enters the house into the same pit and the main control valve for your water line will be in the pit. Having access to your main control valve is vitally important in case you have a water line emergency or leak inside the house.
Another point about your fresh air inlet is that it helps waste water flow smoothly out of the drain system. It is as if you tried to drink out of a bottle and completely covered the opening not letting any air into the bottle.
Air is needed to displace the fluids that are flowing out or it will disrupt the flow of the water. This is also why when routine maintenance is required always make sure that the fresh air inlet is also clear and unobstructed.
Why is a sewer trap so important?
Believe it or not a house trap on a sewer line is vitally important in many ways that you would probably never think of. That “thing” you see in the bottom of a pit in your basement can cause an awful lot of aggravation or damage if it is not functioning properly, is in poor condition, or is not operated properly.
Improper Or Missing Sewer Trap Plugs Or Caps
- Will allow noxious gases to escape into the premises from your sewer line.

- Can allow raw sewage to enter into a premise if a back up occurs.
Trap plugs or caps cost around $10.00 or less each. They are made in at least three varieties, and are readily available from any plumbing supply or local hardware store. They are easily installed on a house sewer using basic household tools or can be installed by your plumber.
Whoever takes the time to install a new plug or cap will be paying a small price for preventing damage, inconvenience, and rodent or pest infestation. In addition this minor maintenance can prevent an unhealthy condition and noxious gases from entering in your property from your drain line. Replacing mussing or improper sewer trap plugs is another case where performing minor plumbing maintenance is well worth the effort .
