Top tips
Hiring a sewer clearance, without the regret.
Four moves that separate a smooth job from a nightmare.
24/7 response matters.
Sewer blockage at 2am is an emergency. Reputable sewer specialists offer genuine 24/7 — confirm before you need to call.
Insist on jetting, not just rodding.
Rodding clears the immediate blockage; high-pressure jetting cleans the pipe. Jetting prevents re-blockage within weeks.
Get a written diagnosis.
After clearance, you need to know why it blocked — fats, wipes, roots, collapse. A written diagnosis informs whether you need follow-up repair.
Check the discharge license.
Septic tanks discharging to ground must comply with the General Binding Rules. Specialists offering 'just empty it' may be hiding compliance issues.
