That’s a really clever idea, I would definitely pay for that in the right circumstances.

Now that I think about it - could you just pour some sort of biodegradable broad-spectrum herbicide down the drain to get the same effect for cheaper?

This is precisely what I do each year with a product designed for this exact purpose. $8+shipping gets me enough for my annual pipe maintenance. It's even the special kind because I have clay pipes.

I don't wasn't to kill parents idea. It's neat, and Im sure there's use cases that my solution doesn't meet

Isn't this a problematic idea? If you flush down herbicide without checking the results, you would risk breeding herbicide resistance in the weeds.

I hope yours keeps working for you. I flushed a lot of blue crystals, but the plant was not deterred.

It will not degrade anywhere near fast enough to not cause serious issues in the biological treatment stage of the wastewater plant.
