When you flush the toilet and water rises in the shower, stop flushing and pause water use, including the washer and dishwasher. The toilet and shower may share a drain, and sending more water into it can make the backup worse.
Check which drains are affected
If just one toilet is clogged and the other drains are working normally, the blockage may be in the toilet or its branch drain. If the shower backs up when you flush, or several drains slow down or gurgle together, the restriction may be farther down in a shared drain or the main sewer line. Tell your plumber what you already noticed. Avoid running more water to recreate an active backup.
How CSR Plumbing narrows it down
We ask which fixtures are affected, what was running when the backup started, and whether it has happened before. We use that pattern and check accessible cleanouts to help locate the restriction. On one sewer clearing job, CSR Plumbing removed heavy tree-root intrusion and restored flow. Recurring backups can warrant a closer look at the condition of the pipe.
