1. Odor: If you can smell nasty odors near the drain field and plumbing appliances, then it is likely that your septic tank is having problems. This can be wastewater or air escaping into your yard.

After a heavy rain, the ground absorbs the extra moisture. So, this is an exception. Otherwise, you need to call in a septic specialist to check what is going on.

2. Puddles of water: If you see large pools of water near the drain field, it is a septic system failure sign. Especially if it has not rained for days or weeks.

That happens because when your septic tanks fails, it stops to absorb wastewater.

3. Greener and brighter grass: We love to see our yard grass green and bright and that is cool. We even use fertilizers and mulch to help us out. But did you know that sewage has the same properties that help your grass to grow as much as mulch?

So, if your yard grass is getting greener and brighter but you have not been using mulch nor has it been raining, it is likely that wastewater is leaking into your lawn.

4. Gurgling sounds: You know you have a septic issue if you start to hear gurgling sounds in your drains and toilets.

5. Sewage backup: If your septic system fails, sewage starts to back up into your house. That is because pipes are blocked and it cannot go to the tank.

If you see wastewater backing up into kitchen sinks, bathroom drains and even your toilet, know you have a septic system failure sign.

6. Slow drains: When was the last time you used the water tap and it was draining slowly? This is a common septic system failure sign.

It happens when your house plumbing pipes get clogged because your septic tank is full. No matter what chemicals or tools you use to unclog your drain, you have to address the underlying problem.
