Kohinoor Sink Waste PVC Pipe,32mm

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.
