The best response to a clogged drain depends on which fixtures are affected and whether the water is merely slow or backing up.
Prevent common blockages
Catch hair at showers and tubs. Keep grease and large food scraps out of kitchen drains. Put wipes and other solids in the rubbish rather than the toilet, even if a label says they are flushable.
A suitable plunger may help with a simple local clog. Avoid putting more chemical cleaner into a drain that is already backed up, and tell the plumber if any product has been used.
Know when to call
A clog that returns soon after clearing, affects several fixtures, or brings wastewater into the home needs a closer look. Stop using affected fixtures when wastewater is backing up. Our drain cleaning service can assess the line and discuss clearing or inspection as needed.
Work out how widespread it is
One slow sink can be a local issue. If a toilet, tub and floor drain are affected together, the blockage may be farther along the shared line. Note which fixtures were used just before the backup. Do not keep running water to “test” a drain that is already overflowing.
Metro Vancouver advises keeping fats, oils and grease out of household drains because they can clog plumbing and sewers. It also says wipes belong in the garbage, even when sold as flushable. Those habits reduce avoidable blockages but will not remove an existing obstruction.
If the problem returns after a simple clearing, read when professional drain cleaning makes sense. Tell the plumber about any chemical cleaner used so the work can be planned safely.
