Buying Guide
Key purchase considerations help you pick the right 1 1/2 inch PVC P-trap:
- Intended application: DWV vs. pressure drainage. DWV is non-pressurized and suits most sinks, while pressure-rated connections require different fittings.
- Material compatibility: PVC traps are common; some kits use polypropylene or mixed adapters. Ensure adapters match your tailpiece and drain pipe sizes.
- Connection type: Unions, threaded nuts, and washers determine maintenance ease and leak prevention. Ribbed nuts offer stronger grip; gaskets reduce leaks at the joint.
- Installation complexity: Kits with included arms, joints, and washers save time. Some require solvent cement for PVC; others rely on threaded nuts and seals.
- Temperature and environment: Temperature ratings indicate safe operation. Typical residential drainage stays well below 140°F.
- Certifications and standards: Look for IAPMO, NSF, CSA, UPC marks for reliability and code compliance.
Practical installation tips
- Dry-fit all components before applying adhesive or tightening nuts.
- Align traps to prevent cross-threading and ensure a straight flow path.
- Use plumber’s putty or appropriate sealant only where recommended by the manufacturer.
- Check for leaks after installation by running water and inspecting joints under slight pressure.
