01
Why the pipe objects
Household drains are designed to carry ordinary water; the main caution is avoiding hydraulic overload in a septic system.
02
Do this instead
Let normal amounts drain normally and fix leaks so the septic system is not processing needless water.
03
Already did it?
Nothing to fix. Just avoid sending a huge volume into a septic system all at once, because excess water can overload it.
