Reasons Your House Smells Like Sewer When It Rains Bankers Hill San Diego

Plumbing is one of the most important, but often underrated, systems in your house. It’s responsible for bringing clean water into your home and carrying waste water out, so it’s no surprise that problems with plumbing can cause big issues—including some pretty foul smells.

One especially nasty odor you might notice is a sewage smell coming from your drains or toilets when it rains. This can be caused by a few different things, ranging from simple maintenance issues to serious problems with your sewer line.

You Have A Clogged Vent Stack

Your vent stack is a pipe that runs vertically through your home, starting at the Sewerage Treatment Plant (STP) and ending at the roof. Its purpose is to allow gases from the sewer line to escape, so they don’t build up and cause problems in your home.

If your vent stack is clogged, sewage gases will have nowhere to go but back into your house. Not only is this smelly, it can also be dangerous to your health.

Your P-Trap Is Dry

The P-trap is a U-shaped pipe that’s installed under every sink in your home. It’s designed to hold a small amount of water at all times, which forms a barrier between the sewer gases and your home.

If the P-trap dries out, either because it’s leaking or because someone has used too much water and flushed it away, the gases will be able to escape and make your house stink.

There’s A Leak In Your Sewer Line

A leak in your sewer line is one of the most serious problems that can cause your house to smell like sewage. Not only is it smelly, it can also lead to sewage waste backing up into your home.

If you suspect you have a leak in your sewer line, it’s important to call a plumber right away. They’ll be able to locate the leak and make the necessary repairs.

Your Toilet Is Overflowing

An overflowing toilet is another problem that can cause your house to smell like sewage. When waste water starts spilling out of the bowl and onto the floor, it creates the perfect conditions for bacteria to grow—which can lead to some serious odors.

Toilets often overflow because they’re clogged. If this happens, you’ll need to clear the blockage so the water can flow freely again. You may be able to do this yourself with a plunger or a snake, or you may need to call a plumber.

There’s A Clog In Your Drainage Pipe

If water is draining slowly from your sinks, showers, and tubs, it could be because there’s a clog in your drainage pipe. This can cause sewage smells because the water is sitting in the pipe instead of flowing freely through it.

To fix a clogged drainage pipe, you’ll need to clear the blockage. This is usually best done by a professional plumber, but you may be able to do it yourself if the clog is relatively small.


There are a few different reasons why your house might smell like sewage when it rains. Most of the time, it’s due to a simple problem that can be fixed with some basic maintenance. However, there are also some serious issues that can cause this problem, so it’s important to call a plumber if you can’t figure out the cause.
