Can this product be poured into the cleanout pipe, outside the house, or is there any specific reason it should be poured into the toilet? Thanks

If you pour it into your toilet, be careful, you have to flush quickly or it will foam out of the toilet and then you will have a mess. I know where my problem is so I use the cleanout pipe. I didn't use it this year (2020) and it cost me $125 to have it snaked out.

How long does it take to work?

It kills the roots immediately. Then the fungi and bacteria rot the dead roots and they wash away over time.

Have two toilets, does it matter which one or should I use it on both? If so, not at the same time? Wait a couple of days apart? Thanks.

use on the toilet that's slow or backed up it goes to the main line to clear the pipe line. The catch is that you must use it every 3 months especially in the winter or rainy months when roots are growing. A plumber used this to clear the line the first time my line got clog and he charged $75 due to the company he worked for. But I am finding it at Home Depot for $16.95 and I live with it and recommend it. I forgot to use it for 6 months and the roots came back but with a repeated use of every 3 weeks my lines are clear again....so get it and stay with it on a regular bases or routine of every 3 months to avoid having a huge plumbing bill.

Which months should this be poured into the toilet? Now is too late?

It can be used any time, but it is best to apply twice a year about 6 months apart. Now is a good time to use and then again in spring.
