Why is my drain blocked?
A drain restriction can be local to a fixture or further along a shared waste route. Identifying the affected outlets helps determine which part to assess first.
Useful steps you can take safely
Use these observations to describe the issue; stop if access is unsafe.
- List which sinks, showers, toilets or external drains are affected.
- Stop adding water if backup or overflow is occurring.
- Tell the plumber about earlier clearing attempts and any chemicals used.
- Keep wastewater areas out of use and leave chamber entry to properly equipped professionals.
What the symptoms may mean
Hair, soap residues, grease, inappropriate waste and physical pipe defects can restrict drainage. These are possibilities, not diagnoses from a slow sink alone. Several outlets reacting together can indicate a downstream restriction, while a recurring blockage merits investigation beyond one clearing.
When professional help is required
Sewage overflow, multiple backed-up fixtures and rapid recurrence need professional assessment. Ask whether the proposed visit covers clearing, investigation or repair. Jetting can clean a suitable line but cannot fix a collapsed section.
Prepare a clear enquiry
Tell Blackstone your exact location, what you observed and what has already been tried. Include photographs only when safe, and ask about assessment and the work scope. See the related blocked drains service below for the relevant next step.
Frequently asked questions
Should I mix drain cleaners to make them stronger?
