PLUMBING PROBLEM GUIDES

Drains & Blockages

Slow drainage, blocked waste pipes and overflowing drains.

Start with where the water has stopped draining, whether it is rising and whether other fixtures are affected. Choose the guide that matches the problem before trying to clear it.

Choose by symptom

One blocked sink and several backed-up fixtures can need different responses. Check the warning signs and whether chemical cleaner has already been used before attempting a DIY step.

Common questions

Which guide matches a slow sink, stopped drain or repeated blockage?

A slow-but-draining sink, standing water that will not drain, and a toilet that blocks again after clearing are separate journeys. Choose the symptom you already see.

What if wastewater is rising or a drain is overflowing outside?

Use the relevant urgent guide for a rising toilet bowl or outside overflow. These explain stop-use, safety and reporting boundaries; they are not general sewer-clearance instructions.

Which guide should I choose for gurgling or a smell?

Use Gurgling drain when sound is the main symptom, and Drain smells for an odour. Follow the odour guide’s gas and returned-water warning routes before treating it as a routine drain problem.
