About this tool.
Why does the interval differ by drain?
A kitchen drain collects grease. A main line collects roots and scale. They age at different speeds.
Can I stretch the interval?
If your notes show the drain staying clear, yes.
What if it says monthly?
Monthly is for heavy-use kitchens and similar drains. A plan keeps it simple.
