"Do not save what is left after spending. Spend what is left after saving."  Warren Buffett

There are times when it makes sense to buy in bulk

if you are paying $280 for a comparable filter and coupling - you will save $500 when you purchase a 6-Pack of ClearFlow filters 

If you are paying $280 for a comparable filter and coupling - you will save $1200 when you purchase a 12-Pack of ClearFlow filters 

The problem with effluent filters
Slide1.jpg

Pressurized septic systems consist of a septic tank followed

by a separate chamber with a pump that sends the wastewater

through a pipe called the force main. When the wastewater

reaches a designated area called the drainfield, the force

main branches into one or more smaller distribution pipes. 

 

The distribution pipes have small holes (orifices) that range in

size from 1/8" to 5/16" in diameter. The orifices allow wastewater

to exit the pipe and disperse into the drainfield.

Distributing wastewater evenly across the drainfield is critical to 

treatment and drainfield lifespan.  Effluent filters are placed in the outlet

baffle of the septic tank to prevent anything larger than 1/8" from plugging

the orifices with debris form the septic tank. Effluent filters have to pulled

out of the tank and cleaned periodically. How often depends upon

water usage and lifestyle.

 

Unless the septic tank is pumped prior to removing the filter, solids will go through

the outlet of the septic tank into the pump chamber. If the filter becomes completely clogged with solids, wastewater can't get through the filter. As a result, the water

level in the septic tank rises until it fills the tank and backs-up into the house.

 

When a completely plugged filter is pulled to be cleaned, it creates double jeopardy. Everything floating above the top of filter case (fats, oils, greases) flows into the 
pump chamber along with everything directly below the case.
 
The most cause of failure in mound septic systems is due to biomat forming
at the interface of the orifice and sand preventing the flow of effluent into
the ground.
"Anaerobic bacteria produce a black, slimy jelly-like permeable layer of partially decomposed organic waste containing microorganisms and their by-products
that seek to feed and grow in anaerobic environment."
Any amount of solid debris will cause major problems when it pugs one or more lateral orifices because effluent will no longer disperse evenly. As a result, some areas of the drainfield will become saturated while other areas do not receive any water. (Below) 
At this point, the system has partially failed.Sooner or later the system will completely
fail without warning.

The Solution

We placed a premium on quality because there are already quality pressure filters on the market. We know our success is dependent

upon going a step beyond current products.

 

The heart of ClearFlow filter is a 316L stainless steel screen that      contains an alloy called molybdenum. Molybdenum increases

strength and hardness and enhances resistance to corrosion.

 

The filter housing, cap & coupling is made of ABS injection                molded plastic. This insures the first part and the ten-thousandth        part are the same.

ClearFlow is the only pressure filter that comes with a 2-inch Camlock quick-connect coupling eliminating the need to

purchase PVC unions or rubberized couplings.

 

Our five year guarantee against defects due to materials and workmanship is a testament to the quality of our filter. 

Not all expensive products are high quality nor are

all inexpensive products poor quality

Compare the price of our filter to other pressure filters,

you'll see ClearFlow costs anywhere from $50 to $100

less depending on where you're located and the the

quantity you choose to purchase. 

Advantages of a pressure filter

​1.  A gravity filter can NOT protect as well as a pressure filter because 

     a pressure filter is placed on the outlet side of the pump. Nothing

     larger than 1/16" can reach the force main.

2.  Unlike gravity filters, ClearFlow will function normally when large 

     quantities of water are used in a short period time. The ClearFlow

     stainless steel screen is 40% open area, which allows flows of

     80 gallons per minute even when the screen is partially clogged.  

                                 

3.  In the unlikely event a ClearFlow filter does completely plug, the tank         alarm will sound. The filter can be cleaned without any debris going   

     into the force main or backup into the home.

Effluent filter clogging is well documented

In the April 2020 issue, of 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. The title of the article was "Top 10 Reasons the Effluent Filter is Plugged." Click here to read the article

Ms. Hager states the number one reason effluent filters plug is 

"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 effluent screen."

Leaks and large parties are examples of such uses.

Regulatory agencies establish "Minimum Standards" 

If an effluent filter is rated at 3,000 or more gallons per day, it greatly

exceeds the daily amount of water used in any residential application.

But, gallons per day is NOT a valid measure of how a filter will function.
