Product Description
Kohinoor Sink Waste PVC Pipe 32mm is a pull-type flexible waste pipe from Kohinoor Impex — a manufacturer with over 40 years of PVC plumbing product experience since 1985. The pipe is sized at 32mm (1.25 inch) nominal diameter with a 30mm internal flow bore, and extends from a compressed length of 500mm up to a fully extended 750mm — giving the installer a 250mm range of adjustment to accommodate varying distances between the basin waste outlet and the P-trap or drain connection without cutting or fitting additional sections. The brass nut fittings at both ends provide a leak-proof, corrosion-resistant threaded connection to standard 32mm waste fittings used across Indian residential and commercial plumbing systems.
The pull-type expandable design is the primary advantage over a rigid waste pipe section — in under-sink and under-basin installations, the exact distance between the waste outlet and the trap or wall drain inlet varies based on cabinet depth, countertop thickness, and drain positioning. A rigid pipe requires precise cutting and fitting; the Kohinoor flexible pipe simply extends or compresses to the required length and routes around minor obstructions without kinking, saving installation time and eliminating the need for additional fittings. The high-grade PVC body resists household chemicals, detergents, and organic waste, and maintains flexibility across its operational temperature range of 5°C to 60°C — suitable for the hot water drainage from kitchen sinks that standard flexible pipes sometimes soften and deform under.
Key Features
- Pull-Type Expandable Design (500–750mm): Extends and compresses to accommodate varying installation distances without cutting — eliminates the need for additional pipe sections or fittings to bridge awkward distances between waste outlet and drain.
- Brass Nut Connections: Corrosion-resistant brass fittings at both ends provide a secure, leak-proof threaded seal — significantly more durable than all-plastic connection alternatives in wet under-sink environments.
- High-Grade PVC Body: Chemical-resistant polyvinyl chloride with 1.5mm wall thickness handles household detergents, cleaning chemicals, and organic waste without softening, cracking, or degrading over time.
- 5°C–60°C Temperature Range: Handles the hot water drainage from kitchen sinks and dishwashers without deformation — a common failure point of lower-grade flexible waste pipes.
- 32mm Universal Compatibility: Standard 32mm size fits all Indian residential and commercial basin waste outlets, bottle traps, P-traps, and wall drain inlets without adaptors.

Installation Guidelines
Step-by-Step Installation
- Measure the distance between the basin waste outlet and the P-trap or wall drain inlet to determine the required pipe length — the flexible pipe accommodates 500–750mm without cutting.
- Extend or compress the pipe to the required length and plan the routing path, ensuring no bend is tighter than the 50mm minimum bend radius to avoid kinking and flow restriction.
- Apply PTFE thread seal tape to the brass nut threads at both ends before connecting — this enhances the seal and prevents thread galling on repeated tightening.
- Connect the upper brass nut to the basin waste outlet — hand-tighten, then snug with pliers. Do not overtighten as this can crack the PVC pipe body at the fitting junction.
- Connect the lower brass nut to the P-trap inlet or wall drain connection in the same manner.
- Run water at full flow and check all connection points for leaks — pay particular attention to both brass nut joints.
- Adjust the pipe routing for a clean appearance and confirm the pipe does not have any sharp bends or contact points that could cause wear over time.
Recommended Applications
Where the Kohinoor 32mm Waste Pipe fits best
- Kitchen Sinks: Chemical-resistant PVC handles grease, detergents, and food debris; temperature resistance up to 60°C manages hot water drainage from dishwashers and hot rinse cycles.
- Bathroom Wash Basins: Pull-type flexibility accommodates tight routing in vanity unit cabinets where a rigid pipe would require precise cutting or additional elbow fittings.
- Utility & Laundry Sinks: Robust 1.5mm wall PVC handles heavy-duty cleaning product drainage and frequent high-flow use without degrading.
- Urinal Waste Connections: Flexible routing allows the pipe to navigate compact under-urinal spaces where rigid pipes cannot be installed without extensive cutting.
- Commercial Washrooms: Brass nut connections provide the long-term leak-free integrity required in high-use commercial bathroom installations.
- Retrofit & Emergency Repair: The adjustable length and flexible design make it ideal for replacing damaged fixed waste pipes in existing installations without disturbing surrounding plumbing.

FAQs
1) What does "pull-type" mean, and how is it different from a rigid waste pipe?
A pull-type flexible waste pipe is made with a concertina (accordion) corrugated body that can be extended or compressed within its length range — in this case 500mm to 750mm — without cutting. A rigid waste pipe is a fixed-length straight or pre-bent section that must be cut precisely to fit and requires elbow fittings for any directional change. The pull-type design saves installation time significantly in under-sink situations where the distance between the waste outlet and the trap varies, and allows the pipe to bend gently around minor obstructions without additional fittings.
2) Can this pipe handle hot water from a kitchen sink or dishwasher?
Yes — the Kohinoor 32mm waste pipe is rated for operational temperatures up to 60°C, which covers the hot water drainage from standard kitchen sinks, hand-wash basins, and domestic dishwashers (dishwasher drain water is typically 45–55°C). Lower-grade flexible waste pipes using softer PVC formulations can soften and deform under sustained hot water drainage, causing the pipe to sag and lose its trap seal depth. The high-grade PVC in this pipe maintains dimensional stability within its rated temperature range.
3) Is this pipe compatible with my existing basin trap and drain connections?
Yes — the 32mm standard diameter with brass nut connections at both ends is compatible with all standard Indian residential and commercial 32mm waste fittings including bottle traps, P-traps, S-traps, and wall drain inlets. If your existing trap or drain connection uses a different diameter (typically 40mm for larger kitchen sinks), the 32mm pipe will not fit directly — confirm your waste outlet and trap size before ordering. In new installations, the plumber will determine the correct size from the basin waste specification.
4) How do I prevent leaks at the brass nut connections?
Apply PTFE thread seal tape (plumber's tape) to the brass nut threads before connecting — wrap 3–4 turns in the direction of the thread. Hand-tighten the brass nut first, then snug firmly with pliers or a spanner. Do not overtighten — the PVC pipe body at the brass nut junction can crack if excessive torque is applied. After connecting, run water at full flow for 60 seconds and inspect both joints carefully — a correctly sealed brass nut connection should be completely dry. If a slow drip appears, tighten a quarter-turn at a time until it stops.
5) How is Kohinoor different from generic unbranded flexible waste pipes available at lower prices?
Generic unbranded flexible waste pipes frequently use softer, lower-grade PVC that deforms under hot water, yellows and becomes brittle within 1–2 years, and has plastic push-fit connections that leak under normal water pressure variation. Kohinoor Impex has manufactured PVC plumbing products since 1985 and uses high-grade PVC with brass nut connections — brass resists corrosion and provides a mechanically secure threaded seal that plastic connections cannot match. For an under-sink waste pipe that will be accessed infrequently and expected to perform leak-free for years, the Kohinoor product offers meaningfully better reliability at a modest price premium over unbranded alternatives.
