Re: Saturated and new to Septic system !!!
Imagination is a good thing, but not to be trusted.
When applying Oxygen treatments you will notice a lot of Bubbling back. Every bubble/Belch/Burp is Lost performance of the application.
You want the Oxygen pushing into the field, not out the end of the pipe.
Upon realizing what was happening to mine, I picked up (2) 4" expandable pipe plugs(Lowes) and after pouring the mixture/+water I capped the pipe.
According to Deck cleaning services the mix has about a 6-8 hour work life.
I Ran about 40 gal.(for my line lengths) with the mix to minimize free space in the lines and force the oxygen to fine exits from the pipe.
After 6hrs. I removed the caps and there was no back pressure of water pushing back.
When treating, we are flooding the field - a lot of water in a short period. So, even though it seems to be draining it needs time to dry out and time for some anaerobic bacteria to die off.
