Buying Guide: Key Purchase Considerations
-
<liCompatibility: Ensure pipe size and connection type match your system (hub, socket, or NPT threads). DWV fittings typically prioritize drainage flow and venting paths over pressure containment.
- Material and code compliance: PVC-DWV is common for residential drainage; verify local plumbing codes and that parts are rated for DWV use.
- Connection method: Hub/socket or solvent-weld connections offer quick installations, while threaded connections (NPT) add flexibility in retrofit projects.
- Temperature and chemical exposure: Most DWV fittings tolerate typical household temperatures and common household chemicals, but confirm temperature ratings for specialized applications (basements, pools, etc.).
- Performance and durability: Look for corrosion resistance, lightweight handling, and ease of maintenance in fittings intended for long-term drainage networks.
- Ease of installation: Hub ends and solvent-weld compatible parts generally provide faster, cleaner installations, especially in tight spaces.
- System type: Identify consider whether your project is residential or light commercial and select fittings optimized for DWV rather than pressurized piping.
- Availability and replacement parts: Choose widely available fittings to ease future repairs and replacements.
