Septic FAQ

Frequently Asked Septic Questions

How Often Should You Have Your Tank Pumped?
There are a lot of variables to how often you pump your septic system, such as the number of people in the home, the amount of water used, garbage disposal use, the size and age of the tank. The size of the septic tank should be determined by the number of bedrooms in the home. For an average home the following is recommended for pumping your septic tank:

Household with 1 Person:  Every 5 years
Household with 2 People:  Every 4 years
Household with 3 People:  Every 3 years
Household with 4 to 5 People:  Every 2 years


What else should I be aware of in the use of my septic system?

Eliminate Grease Discharge
Use Only Biodegradable Products
Limit Use of Garbage Disposals (*see below)

*Why not to use a garage disposal with my septic tank?
Garbage disposals should not be used with a septic system, as they add large amounts of solids which bacteria are incapable of breaking down. The garbage disposal tends to grind the food particles small enough to pass through the septic tank into the leaching field, which can cause permanent damage. If you use your garbage disposal your septic tank should be cleaned annually.


What is harmful to flush into my septic system?
• Food scraps
• Sanitary/personal hygiene items
• Coffee grounds

Riser Installation

Installing risers and lids

The Benefits of Septic Tank Riser Installation
Risers are ultimately all about convenience. They are beneficial for homeowners who no longer want to remove sod and dig several feet into the ground to access their septic tank and make general maintenance of a septic tank easy. Installing an above-ground riser for immediate tank access (and no digging at all) would include many benefits such as no labor to dig up tank lid, and always knowing where your tank location is at just to name a few.


Choosing and Installing Septic Tank Risers
Risers can be made of PVC, polyethylene, or fiberglass. We typically recommend installing risers made of PVC, which is watertight, lightweight, and strong. While concrete risers might be cheaper, they are also far heavier and can crumble and decay over time. When installing a new riser, we will come out to your property to determine the current state of your tank and will review with you all of your options.  All riser lids have a locking system on them so they are safe for children and pets.

To install a new riser on your septic tank, call Danos Septic today. We install risers for all customers in Jefferson, Mason, Peirce and Kitsap Counties. We are always happy to discuss with you your individual septic tank needs.
