Why Does My Septic Tank Smell So Bad?

Septic Tank Bad Smell

Does your home or backyard smell like sewage? Septic tank problems are probably to blame. Homeowners with on-site septic tank systems will occasionally encounter problems that cause foul stenches leaking into their homes.

Unfortunately, septic tank odors are more than unpleasant: they may be hazardous to your health. Gas from septic tank sewage systems may contain methane, carbon dioxide, and hydrogen sulfide. These gases are toxic and may even cause explosions.

Whatever the problem, you’ll want to identify the cause and get your septic system fixed right away. Here are a few problems that may be causing the stench.

Faulty Pumps

Sometimes a bad stench is caused by an over-full septic tank. There may be a faulty pump preventing new wastewater from replacing the old wastewater.

If you’re experiencing a terrible odor in your home and think faulty septic tank pumping might be to blame, contact a septic services professional to evaluate the pump.

A Dry Drain

When a septic drain gets clogged up, it will dry up. This leads to gases that are normally trapped in your septic system seeping into your home.

Dry drains are most likely to occur in bathrooms.

Harsh Weather

Extremely cold temperatures can cause ice and frost to build up around the septic tank plumbing vent. If this vent is blocked, the gas can escape back into your home.

This one is more likely to be a problem in chilly Minnesota than the Pacific Northwest. However, it can happen anywhere after extreme winter weather.

Overly Short Plumbing Vent Pipes

If the foul stench is coming from your garden, you may need to get your plumbing vent pipe extended. Sometimes you just need to get the waste a little bit further away from your home.

You may Need a Filter Filter

Most of the time, the wind will carry the odors away from your home, but that may not be the case depending on where you live. Your home may need a carbon filter on top of the plumbing vent to help mitigate the odors from your septic tank.

If your septic tank system has a carbon filter, it should be changed every 1 to 5 years. Contact a professional to change the filter.

A Poorly Fastened Manhole

Sometimes, a manhole cover that isn’t adequately fitted can result in sewer gases escaping into your home. Have a professional inspect the manhole covers on your drains to ensure they are tight and secure.
