🔗 SMOOTH CHAIN

For plastic pipes – PVC, HT, KG.

Removes grease, soap scum, and soft deposits without damaging the pipe wall. Ideal as a final cleaning step before coating.

✅ Plastic, ceramic, and delicate pipes

❌ Not for hard encrustations or root intrusion

⛓️ SHARP CHAIN

For cast iron, steel, and stoneware.

The cutting teeth break up hard deposits, rust, and root intrusion – where the smooth chain simply can't reach.

✅ Cast iron, steel, stoneware, and concrete

❌ Never use in plastic pipes – the pipe will be damaged.

Rule of thumb:

Soft pipe → smooth chain.

Hard deposits → sharp chain.
