The Problem The Solution
The April 2020 Onsite Installer Magazine published an article written by Sara Hager,
Ph.D. engineer, researcher and instructor in the onsite wastewater treatment program
in the water resources center at the University of Minnesota.
Ms. Hager listed the No. 1 reason filters plug.
"Large volumes of wastewater generated in a short period of time
can result in turbulence in the septic tank and reduced retention
time, which can lead to solids plugging the screen. She states
leaks and large parties are examples of using large amounts
of water in short time periods."

Ms. Hager advises septic system contractors to tell homeowners
not do all the laundry in one day. She goes on to say, spread
laundry throughout the week and wash at times when there
is not a lot of water being used. Do not run multiple water-
using devices at the same time, such as showering or
running the dishwasher while doing the laundry."
We believe putting the onus on septic system owners is misguided.
This doesn’t have to happen in septic systems that utilize a pump
to move wastewater from the tank to the leachfield.
When a effluent filter plugs, wastewater can not exit the septic tank.
Wastewater rises until it reaches the top of the tank.
It then backs up into the inlet pipe coming from the house.
Finally, it backs up into the lowest level of the house.
When the filter is pulled out of the septic tank, the wastewater and solid matter that has risen to the top of the tank will flow through the outlet into the pump chamber.
where it quickly passes through the pump into plastic pipes that disperse wastewater to the drainfield.
"Success is simple. Do what's right, the right way, at the right time."
-
There are 30 million septic systems in the U.S.
-
Very few understand how their septic system works.

They are counting on you.

ClearFlow Overview
-
Provides protection for all pressurized systems
-
Mounts on the discharge port of any effluent filter
-
Easy to install, easy to service, requires little maintenance
-
Comes with a 2" quick-connect coupling, makes service easy
-
Stops anything larger than 1/16" from migrating to the drainfield
The 316L stainless steel screen is 3" diameter by 18" long
-
316 provides protection against corrosion in harsh environments
-
L stands for low carbon; provides additional corrosion protection
-
The stainless steel contains an alloy called molybdenum
-
Molybdenum increases strength & enhances corrosion resistance
-
Fluid head loss is 1.92 feet (.831 psi) at 50 GPM
-
Engineering Analysis (Click here)
It is not affected by large water usage in a short period of time
-
A partially plugged screen will continue to function normally
-
If ClearFlow filter does completely plug, the pump alarm sounds
-
The screen can be pulled and cleaned without risk of migration
-
When the pump runs, the vibration provides a self-cleaning effect
The plastic pipes are called laterals.
-
Laterals have small holes (orifices) that disperse wastewater to the drainfield.
-
Orifice size ranges from 1/8" to 5/16" in diameter.
-
When solid matter enters the laterals, orifices plug.
Pressurized system design is based the entire drain field be utilized
-
Plugged orifices create uneven wastewater dispersal to the drainfield
-
Uneven dispersal causes some areas to receive excess wastewater
-
These areas become saturated creating oxygen-starved soil
-
Saturated, oxygen-starved soil produces anaerobic bacteria
-
Anaerobic bacteria create biological waste matter called biomat
Biomat is a blackish, jelly-like, permeable layer (right)
-
It forms on the sides and bottom of the drain field.
-
As long as water is being used, the ground will remain wet.
-
As long as the ground remains wet, anaerobic bacteria will multiply.
-
This progression will continue until the entire drain field is covered by biomat.
