How to Unblock a Drain with Rods

Drain rods are long, flexible rods that screw together end-to-end and are pushed through a blocked drain to break up or dislodge the blockage. They're the classic DIY drain unblocking tool, available from most hardware stores for around £20–£40. However, using them incorrectly can make things worse or cause damage, so following the right technique is important.

What to Look For

• Always push and twist clockwise — never anti-clockwise (rods unscrew)
• Start from the nearest manhole downstream of the blockage
• Use a plunger attachment first, then switch to a corkscrew if needed
• Work the rods gently — forcing them can damage pipes
• If rods won't clear the blockage after 15–20 minutes, call a professional
• Never use rods on internal plumbing — they're for outside drains only

How We Diagnose the Problem

If drain rods successfully clear the blockage, test by running water for several minutes to confirm flow is restored. If the blockage returns within days or weeks, there's an underlying structural problem that rods can't fix — a CCTV survey is the next step.

How We Fix It

For recurring blockages, professional CCTV investigation reveals the structural cause — whether it's a partial collapse, root ingress, or pipe gradient issue. Rods treat the symptom; professional diagnosis and repair address the cause permanently.
