A completely blocked drain should not be treated like an ordinary slow drain. Continuing to run water can cause the fixture to overflow or force wastewater toward another opening in the drainage system.
1. Stop using the affected fixture
Do not continue filling a sink, running a shower, flushing a repeatedly clogged toilet, or operating an appliance that drains into the affected line.
2. Check nearby fixtures
If another sink, toilet, tub, or floor drain is also backing up, the obstruction may be farther downstream than a simple fixture clog.
3. Avoid repeated chemical drain cleaner use
Chemical products may not reach or remove a serious blockage and can create additional hazards for anyone who later opens or services the drain.
4. Watch for wastewater coming up elsewhere
Water appearing in a shower, tub, floor drain, or another low fixture when you use plumbing elsewhere can indicate a larger drainage problem.
5. Call for professional drain cleaning
Persistent, recurring, or multi-fixture clogs should be diagnosed rather than repeatedly treated at the surface.
6. Stop water use if sewage begins backing up
If contaminated wastewater is entering the home, stop using plumbing fixtures in the affected area and treat the situation as an emergency.
If sewage is already backing into the property, see our emergency sewer backup repair in Framingham.
