House Smells Like Sewer When It Rains Do This?

I am sure it has occurred to all of us at some point: you wake up on a misty morning or step into your apartment after traveling in the rain and something doesn’t feel right!

Whenever it rains, your home stinks like a sewer rather than a pleasant, fresh, pure aroma. For some circumstances, you detect a strong odor that reminds you of a sewage overflow. What exactly is going on? What is the deal with your house smelling like a sewer? Today, I will delve into possible reasons, solutions, and preventative strategies.

Why Does Your Home Smell Like Sewer When It Rains

Whenever it rains, a sewage odor in the house is produced by fractured sewer pipes or a septic system, stagnated drain traps, faulty toilet wax rings, or a jammed plumbing vent. Rainfall also makes the air dense, keeping sewer gasses from escaping and remaining low to the ground, contributing to the sewage stench.

Once it rains, the atmospheric pressure changes in pressure, causing the air around your house to become heavy. This prevents sewage gasses from moving away from your home through the outlet, instead saturating the air low on the ground and causing the sewer odor in the household.

Whenever it pours, ensure that all drain traps are full of water, that the plumbing outlet is clean, that there are no wobbly toilets, and that there are no clogged drains. If you believe the issue is a cracked sewage line or septic tank, get it checked by a certified plumber. Let us take a closer look at why you have a sewage stench in your home when it rains and what you may do to address it.

Science Behind It

Once it rains, the rainfall outflow has to go someplace. Gravity causes it to flow to the lowest spot it can, generally into any accessible culvert or crack in the tank. As the water accumulates, it takes up room, forcing the gas to rise to meet the growing volume of water. Since gasses have a lesser density, they will begin to leak from sewers, causing a foul odor in the meantime.

P-trap

Your plumbing system was designed to be a waste tunnel. When we speak about waste in this context, we are referring to both human and organic waste. The bulk of organic waste originates from substances that are thrown away, such as food leftovers. If too much is poured down the drain and there is a backlog, an unpleasant odor might emerge. If you detect a stench, have it repaired since the scent might be harmful.

Do you know what a P-trap is? It is where all of your wastewater is stored. The trap itself forms a seal and serves as a barrier between the foul sewage odor and the remainder of your home. The p-trap might degrade with time, resulting in a strong stench.

In the mechanism of domestic toilets, there is a p-shaped sewage trap where water gathers, producing a buffer between sewer gasses and your home. If the trap is not correctly sealed with sewage plugs, or if the plugs have broken loose, the outcome will be escaping sewer gas — or, in other terms, a foul odor.

What is the Solution

If you are skilled, you might be able to repair the P-trap manually. There are several great internet tutorials that will put you in the proper way. Nevertheless, for the majority of us, it may be advisable to contact a skilled plumber. Plumbers provide free quotes in the majority of the country. A plumber can visit your house and accurately analyze the problem, as well as give a free repair quote.

Wax Ring

The wax ring at the bottom of your toilet aids in maintaining a seal between the toilet and the drain pipe. When a seal is damaged, it might result in a leaking toilet and a foul odor. Sewer gas can flow up through your sewer pipes and, if the wax ring breaks, seep into your household, causing an unpleasant odor.

What is the Solution

If your wax ring breaks, it must be changed. To reach the ring, the toilet must be emptied and uninstalled. The old worn out wax ring is frequently in poor shape and must be scraped off the toilet flange. Make sure to clean the area surrounding the toilet flange with cleanser or vinegar if necessary.

Inactivity

If your home stinks like a sewer when it rains, a probable explanation might be a dried-out water barrier in the sewer trap, which is generally caused by inactivity.

If you have a fixture in your house that is not used frequently, such as a basement bathroom shower, the water barrier within the sewage trap might dry up.

What is the Solution

The easiest method to repair this is to fill the trap belly with water from that fixture and reestablish the water barrier. Likewise, if a leak causes the seal in the p-shaped trap of a toilet to leak, sewer gasses can begin to ascend. As a result, the gas may escape and settle within your household, causing severe damage.

In conclusion, sewer gas may enter your home through current sewer lines everywhere there is a drain. Rainy seasons might exacerbate the issue by driving gasses out. If you smell sewer anywhere around your house, it is a warning that you have a plumbing problem that has to be addressed right soon. In most circumstances, you will want the services of a competent plumber to inspect the issue.
