What Is A Septic Tank Lid?
The septic tank lid is a key component of the tank that helps keep in the gases and also keeps out dirt and other unwanted objects from falling into the tank.
More importantly, it serves to prevent accidents such as kids from falling into the tank.
This primary access into the septic tank is used by septic tank companies every few years to inspect as well as pump the tanks. Sometimes, some shallow digging will be necessary to access your septic tank lid.

Common Issues With Septic Tank Lids

Which is Better: Replacement or Repair?
Before we get into details on how to replace your septic tank lid, it’s important to discuss the choices before you. When a septic tank lid gets faulty, you’re left with two options; to repair or replace.
The repair depends on the level of damage.

Steps To Replacing Your Septic Tank Lid

So, what are these procedures?
You’ll first need to locate the lid, dig up the lid area, and determine the replacement lid type needed. Lastly, the old and faulty septic tank lid has to give way to the new.
Let’s further discuss each of these procedures for the sake of clarity.
Locating the Septic Tank Lid
Replacing a septic tank lid isn’t as easy as it sounds as you’ll have to search out the lid area.
First, you must know where your septic tank is located. Thankfully, maintaining scheduled inspections enables you to discover issues as early as possible.
The best way to save time in locating the septic tank and lid is by calling for professional help or contacting the previous property owner. Another effective way is by making inquiries from your local health department.
These organizations keep records on building permits etc.
You may want to try the metal detector approach. Will this work for concrete tanks? It will! Concrete tanks have metal rebar within their structures. A metal detector search leads you to the general area where you continue with further investigations.
If you’ve found the general area of your septic tank, it should be lying about 12 to 14 inches below the ground. So, a metal poke around such an area should help you proceed to the next step.
Digging up Lid Area
The first process has enabled you to find your septic tank, now, you’ll have to do a little digging to gain access to the lid. When working with a record of your property, you’re able to anticipate ahead of time how many lids there are.
Using a shovel for this task should suffice.
Having located the lid, you’ll need to dig out the sides to allow for more clearance. Most septic tank lids lie flat against the tank. With more lids comes the need for increased clearance of the top surface of your tank.
Thankfully, not much digging will be necessary because the depth of the lid should start from around 4 inches.
Determining the Replacement Lid Type Needed
Gaining access to the septic tank lid enables you to determine the exact replacement type to purchase.
No purchase can be made until this step is completed. The lid material doesn’t count so much because there are alternatives such as those made of PVC that will serve just fine.
Getting a new replacement lid for your septic tank is likely to cost you around $100 to $200 based on the type you purchase.
Replacing the Old for the New
To fix the new lid, the old has to be removed. Depending on the lid, removal may be easy or a bit challenging.
Tools such as a pry bar or backhoe should help with lifting heavy septic tank lids. Having removed the old and replaced the new, it will need to be secured in place.
These are ways to go about replacing a septic tank lid.
Following the process laid out above guarantees a better job. Your septic tank condition should be better improved with this maintenance action.
