Why We Use Chain Knocker Cleaning (and When We Still Jet)

Hydro jetting is powerful—but on older clay, cast‑iron or Orangeburg pipe it can be too aggressive. Our go‑to method is Picote chain‑knocker cleaning: a controlled way to remove roots and scale without damaging the host pipe.

Real Results, Less Risk

Chain knockers clear roots and mineral scale while keeping wall thickness intact. After cleaning, we camera‑inspect the line to confirm results and check for structural defects.

When Cleaning Isn’t Enough

If roots keep coming back or the pipe is cracked/offset, we can install an epoxy liner to restore structure and stop intrusion—without digging up landscaping.

Chain Knocker & Jetting FAQs

Is chain‑knocker cleaning safe for all pipes? It’s ideal for clay, cast‑iron and Orangeburg pipes where jetting could be too aggressive. For newer PVC lines we often use hydro jetting instead.
When do you still use hydro jetting? We jet newer PVC lines, heavily greased kitchen lines or as a final flush after descaling with chain‑knockers. Each job is assessed individually.
How long does a typical cleaning take? Most jobs are completed in 1–2 hours including inspection, cleaning and final camera verification. Severe blockages may take longer.
Can I watch the camera inspection? Absolutely—we encourage homeowners to see the before and after. We’ll show you live footage and explain what we’re seeing.
Do you offer epoxy lining if cleaning isn’t enough? Yes—if the pipe has cracks or recurring intrusion we can install an epoxy liner after cleaning. See our sewer relining page for details.
