Frequency of using coffee grounds in the toilet
Unfortunately, after a few days the situation will almost return to normal. To avoid this, it is recommended to repeat the procedure once a week, at most every 12 or 14 days , to achieve optimal results.

Alternatively, you can take a saucepan, pour warm water inside, submerge 3 tablespoons of coffee grounds, mix them and pour them down the toilet. The longer they remain in contact with the bottom of the toilet and the pipes, the more the problem can be resolved as the days go by.
