Fixture & branch drain clearing
Grease, wipes and foreign objects are common causes; the plumber checks whether the main drain is also involved.

What this covers
Clearing sinks, showers, baths, laundry and branch lines.
Do this first
- Keep clear of sewage and electrics near standing water.
- Avoid pouring more water into a blocked fitting.
- Note whether multiple fixtures are affected and photograph any overflow if safe.
