Before using a drain flies remover, you will want to think about the root cause.

Most will want to get started by getting rid of the drain flies in the toilet but that is not going to fix the main issue.

To look at what is going on, you will want to shut off the main water valve.

Shut this off to make sure water is not going into the fixture.
