How to Replace Septic Tank Risers
installing septic tank risers is a great way to make cleaning out the tank much easier and convenient. Septic tank risers are used to help locate the septic tank lid so that you can quickly remove it for pumping out. These easy to install risers are very cost effective for a homeowner who needs to have their tank cleaned or repaired. To have a professional walk around your yard searching for the tank can add up to hundreds of dollars.
In the event that the septic tank riser is damaged, they are very easy to replace. Simply choose the material that you want for the riser and remove the old portion. Here are some simple steps to replace the septic tank riser to continued ease in locating the lid.
Step 1: Dig Out Old Risers
Usually the damage to the risers is caused by frost heaving the ground, a piece of heavy equipment, or a lawn tractor catching the edge with the blades. When this happens you can easily replace the risers by digging down to the surface of the septic tank. The use of a shovel for this part will minimize other damage that can occur. It does take time, but worth the effort.
Step 2: Excavate Around Risers
It is necessary to dig out from the risers at least 10 inches so that you will have room to work. Make sure that the ground slopes inward from the top to minimize any dirt that will fall back into the hole and eventually into the septic tank.
Step 3: Remove Riser Lid
The lid is going to be compatible with the type of risers that are used. For example, if concrete risers are used, then the lid will be made out of heavy concrete. Many people use PVC risers to make the installation easier and the lid lighter. It is held in place by two pins. Remove the pins and lift off the lid.
Step 4: Remove Risers
Each riser is going to be either 6 inches or 12 inches. It is going to depend greatly on how deep the septic tank actually is. There may be multiple risers used to get the lid to the top of the ground's surface. They stack on top of each other and screwed together to make them secure and watertight. Remove the screws and risers.
Step 5: Remove Ring if Damaged
To make the septic tank risers compatible with the tank, an adapter ring is used. If it is damaged, or you are using a different material, replace it with a new one.
Step 6: Stack Risers
Set one of the new risers onto the ring and screw it in place. Then continue stacking the risers until it reaches the surface of the ground.
Step 7: Add Rider Lid
Now that the new risers are in place you can attach the new riser lid. It secures to the top riser with the use of screws. Tighten them up and make sure it is secured.
Step 8: Backfill Soil
With the septic rank risers in place, use your shovel and backfill the soil. Stamp it down with your feet for a compact fill.
