Septic Tank Repairs

What is a septic tank?

A septic tank system is a common way to dispose of household sewage where there is no connection to a municipal sewer system. Septic tanks are often used when the house is located on too small of a lot for city sewer service, or if the terrain makes it difficult to get city water and sewer lines installed. Homeowners may also opt for septic systems because they are less expensive than having city water and sewer services installed.

Septic tanks are the most common type of onsite wastewater treatment system. They treat household wastewater so it is safe to release through a septic drain field into the ground. Most septic tanks consist of a concrete box or fiberglass tank with an inlet and outlet. The inlet allows waste to flow into the tank, and then be pumped out by a submersible pump at regular intervals or when needed.

The baffle separates incoming effluent from outgoing effluent, keeping each stream separate so they don't mix together as they exit through an outlet pipe at the bottom of your tank.

Each tank has an inlet baffle to slow the flow of water and solids entering the tank. The baffle helps to prevent the tank from overflowing, especially if it is not completely full.

There’s also a septic tank outlet baffle or “effluent filter” on the other end to keep solids from leaving the tank and going into the leach field. The outlet baffle is a device that prevents solids from leaving the tank. It's also called an effluent filter. The baffle has to be cleaned out every two to three years, depending on how much use your system gets. The baffle should be cleaned out and inspected by a qualified septic system installer or service provider if there are any signs of structural damage or deterioration, such as cracks in its plastic housing, broken legs, rusted joints, and/or corrosion around screws.

When wastewater enters your septic tank, it flows through a series of chambers called compartments. As the wastewater passes through each compartment, solid particles are separated from liquid and dissolved solids. The solids settle at the bottom of these compartments, forming sludge that can be removed periodically for disposal; liquids, dissolved waste and oils rise to the top as scum. The last chamber contains an outlet tube connected to a leach field or drain field where effluent drains from all four chambers into perforated pipes buried in soils where bacteria break down organic matter into harmless by-products.

The bacteria in the septic tank break down organic matter, fats, oils, and grease. They also break down human waste and paper products like toilet paper. The effluent then flows out into a leach field or drain field, which is a series of perforated pipes covered with gravel, located in trenches covered with dirt or grass. The septic tank effluent is dispersed through the soil in these trenches by anaerobic bacteria, which consume the remaining organic matter and pathogenic organisms.

Repairing a cracked tank

If you have a cracked septic tank, the best option for repair is to hire a professional. A cracked septic tank can be dangerous and may lead to structural damage in your home if it is not repaired properly. A professional will be able to determine if your tank has been damaged by cracking and ensure that it is repaired properly so as not to cause any further damage.

How do you know if your septic tank is cracked?

There are several signs that indicate whether or not a septic system needs repairs:

  • Leaking from the bottom of the tank or from its lid (if it has one)

  • Bubbling around the top of your drain field area during precipitation events like rain storms or snow melt periods (this indicates that water is entering into areas where it should not)

Installing a new baffle

To install a new baffle, you’ll need to:

  • Pry the old baffle out of place. If it is broken, you may be able to remove it by pulling on it gently. If not, use a hammer and chisel to free up all sides.

  • Cut out a piece of corrugated pipe that will fit into the tank but still allow for water to flow through it (at least 3 inches in diameter). You can buy this at any DIY center or plumbing supply store. Use a hacksaw if necessary.

  • Clean out any debris from inside the tank that was left by removing the old baffle, then put your new one in place with some silicone caulk on its edges so that nothing can leak through them again! Be sure that everything looks good before turning on your septic system again—you don’t want black sludge seeping up into your yard!

Replacing the drain field and pump

A drain field is a system of pipes that carries wastewater to the leach field, where it's dispersed into the soil. A pump moves the wastewater through this pipe system, and if your old pump dies or breaks down, you'll need to replace it. There are four types of pumps: submersible, jetting, belt-driven and centrifugal. The costs will vary depending on what type you get and how long ago yours broke down.

Another thing to consider when replacing a drain field is how much water pressure there is in your house; if it's too low or high for whatever type of pump you choose (jetting pumps require more pressure than others), then installing new plumbing lines may be necessary before installing any kind of new equipment because otherwise there won't be enough power going through them at all times during operation.


There are many options for disposing of wastewater in your home, but septic systems are a popular choice. They're simple, cost-effective, and efficient. A septic tank is just one part of this system though; you'll also need an inlet pipe from your house leading into the tank, an outlet pipe leading out of the tank into a leach field or drain field (which can either be onsite or offsite), and possibly other pipes depending on where yours is located. The biggest issue with installing one yourself is making sure all these pieces fit together correctly so that they work correctly as well!
