Ah yes, the joy of septic systems.

We're in need of a pumping here, as well. I have become well-versed in the shitty business of hosing the filters on the outlet side and backwashing the main pipe from the house on a quarterly basis to get caky buildup out of there.

In fact, it all went into my very first "shitpost" on Hive...

Good luck with your system. I hope you can fix most if it yourself, because the "pros" seem to charge $250 just to start the truck for a service call.
