You’re welcome, this is my first house with a septic system, and it has been a learning experience for me as well. I believe my septic guy said the filters were optional when most of the houses were built around me, but are now required to be installed here. Many people remove the filters instead of cleaning them, and the first septic company we used never even mentioned the filter was not there. I clean the filter each time I check the solids level in the tank, I would rather do a bit of maintenance than spent $20,000+ replacing a drainage field.@Ischgl99
The septic system I own is my first and was there when I bought the property.
Your post is the first I've ever heard of the filter.
Thank you for the info. Not hobby metalwork, but very useful for me.
I'll check it out when I get back to that property.
