1. The hoses are telescopically extendable, not stretchable Even though the description says “length 30–60 cm,” they are not elastic or meant to be pulled like a spring. They’re corrugated stainless-steel hoses inside — which are semi-rigid and do not stretch by force. The “30–60 cm” range refers to: 30 cm – their minimum installed length (when the hose is gently curved or compressed). 60 cm – the maximum length you can reach by manually extending the corrugated section (usually by hand, carefully, in a straight line). So the extension is limited and must be done slowly and evenly. 2. How to extend correctly Hold both fittings firmly (the G1″ threaded ends). Gently pull apart with both hands, in a straight line. You’ll feel slight resistance — that’s normal. Stop if it feels tight or starts to deform. Do not twist or bend while pulling — twisting can damage the corrugated metal inside. Once you reach the desired length (up to about 60 cm), position it without tension and avoid sharp bends (minimum bend radius ≈ 5–6 cm). ⚠️ 3. What not to do ❌ Don’t use tools (pliers, wrenches) to pull or twist the hose. ❌ Don’t install it under tension — it must be relaxed between connections. ❌ Don’t exceed its maximum extension (you’ll feel a stop point). ❌ Don’t bend it tighter than a 5–6 cm radius. ✅ Tip If the hose seems too rigid or doesn’t reach comfortably, use: a slightly longer version, or a short rigid pipe piece or union fitting to bridge the gap — never force the flexible hose.
