Baffles in a septic tank are provided to keep solids and floating scum and grease inside the tank. Baffles are provided at both the inlet to the tank (from the building) and the outlet from the tank (to the absorption system). The steel septic tank shown above at left has a baffle that is rusted away at its top.
Is a baffle necessary in a septic tank?
A baffle is also necessary at the outlet end of the tank. It allows sewage effluent to flow out of the tank, while retaining the floating scum made up of grease and soap residue in the tank to be removed when the tank is cleaned.
Can you repair the baffle in a septic tank?
If the baffle becomes damaged or is forced out of place, it would be impossible to repair. This is because repairing it would effectively mean digging the septic tank out of the ground and attempting to break it in to two halves again!
What happens if septic baffle is clogged?
The outlet baffle keeps solids from traveling down the line to the leach field, since that could clog the pipes. The inlet baffle helps the wastewater enter the tank smoothly. A clog in either of these baffles can prevent wastewater from draining correctly. Like a drain clog, this type of clog will slow or stop drains.
How long should a septic tank baffle be?
The inlet baffle should extend at least 6 inches, but no more than 12 inches into the liquid level of the tank. The inlet baffle should extend 12 inches above the liquid level of the tank. This is a total baffle length of 18 to 24 inches.
What does a baffle do?
Baffles are flow-directing or obstructing vanes or panels used to direct a flow of liquid or gas. It is used in some household stoves and in some industrial process vessels (tanks), such as shell and tube heat exchangers, chemical reactors, and static mixers.
How do tank baffles work?
Baffles work by disrupting the flow pattern and providing top to bottom flow within the tank. When mixing solid suspensions in a large cylindrical tank, without baffles you will normally end up with a swirling flow pattern within the tank.
How often should a septic tank be pumped?
As a general rule, you should only need to empty your septic tank once every three to five years. That being said, the actual frequency will vary depending on your usage and how many people are living in your home.
How do you tell if your septic tank is full?

What is concrete baffle?
Most concrete septic tanks have precast concrete baffles inside the tank to keep the major solids from going out into your septic drainfield. Over time, these concrete baffles erode and can’t do their job efficiently. As a result, too many solids enter the drainfield.
How does an effluent filter work?
An effluent filter is a cylindrical device installed on the outlet baffle of a septic tank that assists in the removal of solids from wastewater before it enters into a drain field. These effluent filters are designed to protect the drain field and allow for cleaner and more clear effluent to exit the tank.
Why does my septic baffle keep clogging?
Why Does a Missing Inlet Baffle Cause Intermittent Clogs? As you use your home’s plumbing and flush wastewater into the septic tank, the scum layer will rise. When the inlet baffle is damaged or missing, this allows the scum layer to block the inlet pipe in your septic tank.
How do you get roots out of septic lines?
Flush 2 pounds of granular copper sulfate down the toilet for every 300 gallons of water that the septic tank holds. Copper sulfate kills and dissolves tree roots as they absorb the tank’s water. After entering a tank, the majority of copper sulfate settles in tank, and little passes into the leach bed line.
How far down is outlet on septic tank?
After the solids settle out, effluent leaves the septic tank through the outlet pipe and flows to the drain field. The outlet pipe should be approximately 3 inches below the inlet pipe.
What is an effluent filter?
Effluent filters are devices that can be affixed to outlets of septic tank and grease trap as pictured at right (Figure 1). The filter is a primary screening barrier designed to reduce the volume of solids passing out of the tank and through to the soil absorption system (SAS).
What is baffle wall?
The baffle wall is approximately the same size as the screen, providing a solid, smooth uninterrupted surface to distribute sound throughout the auditorium. It produces a large sound image and accurately tracks sound elements with the onscreen action.
