Frequently Asked Questions
How does John The Plumber handle a recurring drain blockage?
It assesses the symptoms and accessible drainage, then chooses an appropriate method. After service, it checks how the affected fixture or line drains and explains possible next steps if it finds signs of a larger or recurring issue.
What does the drain-cleaning warranty cover?
A limited 30-day warranty covers recurrence of the same blockage under normal use conditions.
Does every drain blockage need a camera inspection?
Many common blockages can be addressed without a camera inspection. A camera may help when a blockage recurs or symptoms suggest an issue farther along the line, and the drain may need to be cleared first for a useful inspection.
