What is upvc P-Trap 4″ GM ?
Detailed Specifications
| Parameter | Details |
|---|---|
| Material | uPVC (Un plasticized Polyvinyl Chloride) – rigid, non-toxic, and UV-stabilized for indoor/outdoor use. |
| Nominal Size | 4″ (110mm outer diameter; inner diameter ~102-105mm depending on manufacturer). |
| Schedule | Sch 40 (standard wall thickness: ~0.237″ or 6.02mm for 4″ size, providing balanced strength and flow). |
| Pressure Rating | Up to 160 PSI (pounds per square inch) at 73°F (23°C) for water; derates at higher temperatures (e.g., 100 PSI at 100°F/38°C). Non-shock pressure for continuous use. |
| Joint Type | Socket (hub) x Socket or Hub x Male (GM) threaded; solvent cement weld or threaded connection. |
| Temperature Range | 32°F to 140°F (0°C to 60°C); maximum service temp 140°F with reduced pressure. |
| Standards Compliance | ASTM D1785 (pipe/fittings), ASTM D2466 (Sch 40 fittings); MS 1063 for drainage; ISO 9001 certified by local brands. |
| Dimensions (Approximate) | – Trap depth: 4-6″ (100-150mm) – Overall length: 8-12″ (200-300mm) – Weight: 0.8-1.2 kg per unit. |
| Color | White or grey (industrial). |
| Other Features | Low thermal conductivity (insulates better than metal); fire-resistant (flash point ~730°F/388°C); water absorption <0.06% after 24 hours. |
Installation Guide
Installation is straightforward and typically takes 15-30 minutes per fitting. Tools needed: PVC primer, solvent cement, pipe cutter, deburring tool, measuring tape, and gloves. Follow these steps for solvent weld joints (preferred for Sch 40 pressure systems; use thread sealant for GM threaded ends):
- Preparation:
- Measure and cut uPVC pipe to length using a pipe cutter for a square edge.
- Deburr the pipe end (inside and outside) to ensure a clean fit.
- Dry-fit the P-Trap to the sink/drain outlet and downstream pipe to check alignment and trap depth (minimum 2″ water seal).
- Priming and Cementing:
- Apply PVC primer to the pipe end and socket interior (wait 10-15 seconds for softening).
- Immediately apply a thick layer of solvent cement to both surfaces.
- Insert the pipe into the socket with a 1/4-turn twist for even distribution; hold for 30 seconds.
- Assembly:
- Connect the upstream end (from sink) to the trap’s inlet (usually straight socket).
- Attach the downstream end (to wall pipe) via the curved outlet; use the GM male thread with Teflon tape if threaded.
- For vertical installations, ensure the trap arm slopes downward at 1/4″ per foot for proper drainage.
- Support the assembly with straps every 4 feet to prevent sagging.
- Curing and Testing:
- Allow 15-30 minutes curing time (full strength in 24 hours); avoid pressure testing during this period.
- Run water through the system to fill the trap and check for leaks. Pressurize to 1.5x working pressure (e.g., 240 PSI for 160 PSI rating) for 10 minutes if in a pressure line.
Safety Tips: Work in a ventilated area (solvent fumes are strong). Do not use for hot water >140°F or chemical drains without compatibility checks. Local codes (e.g., IPC or local plumbing standards) may require permits.
Usage
This fitting is primarily used in:
- Drainage Systems: Sink traps, floor drains, or shower outlets to hold water seals against gases.
- Pressure Applications: Irrigation, pool plumbing, or cold water supply lines (Sch 40 rating handles up to 160 PSI).
- Industrial/Commercial: Wastewater conveyance, rainwater harvesting, or ventilating pipes in buildings.
- Residential: Kitchen/bathroom setups, especially in humid climates where uPVC resists mold.
