do septic tanks smell?

Do Septic Tanks Smell?

The simple and shot answer to this question is yes, septic tanks smell. There are a plethora of very pleasant fragrant smells to enjoy in the United Kingdom, but the smell that oozes out of septic tank systems are certainly not one of them. In fact, if you care for yourself a lot, you should not even try smelling your septic tank at all. However, if you do notice a bad odour wafting from the direction of your tank, it may be that there’s an indication that something is not right. The septic tank system is always with strong malodorous scents, but when you start smelling the odour from the septic tank on your property, then something is wrong and if ignored, may lead to a contamination of your water supply and or other dangerous situations.

✓ When you’re able to perceive the smell of your septic tank from your property, it may imply a full or overflowing septic tank. In this case, you should call in a professional to have your tank pumped. Generally, most tanks are designed to be pumped every 4 years but this is definitely going to vary depending on the size of of the tank as well as your home’s water usage.

✓ Another possible reason for a smelly tank is a covered septic tank vent. This usually happens when a home is renovated or remodelled after the septic tank system has been fitted. You should make sure that the septic tank vents are always uncovered.

✓ If the septic tank starts to get smelly right after showering, then it’s most likely that the septic tank was not installed the way it’s supposed to and may have been fitted without any type of vent.

✓ A smelly tank can also be caused by inappropriate items making their way into a system like cooking grease, oil or fat, paints, solvents, industrial cleaning products, condoms, feminine hygiene products and so on.
