NIBCO Fig No U4885: 2″ PVC DWV P-Trap Hub x Hub
The NIBCO U4885 is a 2″ PVC DWV P-trap with hub ends designed for solvent-weld connections to male unthreaded pipes or fittings. It provides a water seal to prevent sewer gases from entering occupied spaces. Best for new installations or replacements in PVC-DWV systems where corrosion resistance and light weight are advantageous. Caution: not intended for pressurized systems.
Asterbacks 2″ PVC P-Trap With Solvent Weld Joint
The 2″ PVC P-Trap from Asterbacks uses a solvent weld joint and is designed to connect two pipes of the same diameter. It is suited for 2″ SCH 40 PVC pipes and is easy to install with primer and solvent cement. Best for quick, straightforward installations and for users seeking a lightweight, durable PVC option. Limitation: suitable temperature range and non-toxic compatibility should be verified for specific fluids.
AB&A Trap-Tite 2″ Floor Drain Trap Seal
Designed for floor drains and other maintenance drains, the AB&A Trap-Tite helps mitigate trap seal loss due to evaporation and blocks sewer gases and pests from entering a building space. Best for areas where evaporation is a concern, such as basements or mop stations. Limitation: primarily a seal device for drains, not a standard P-trap replacement in all DWV configurations.
Charlotte Pipe 2 DWV P-Trap with Solvent Weld Joint
The Charlotte Pipe 2 DWV P-Trap uses a solvent weld joint and is black, intended for sanitary drain, waste, and vent lines. It is not designed for pressure use and should be used in systems where the temperature does not exceed 140°F. Best for standard DWV installations where solvent-weld joining is preferred. Limitation: not suitable for pressurized sections or high-temperature applications.
NIBCO Fig No U5885: 2 in. ABS DWV P-Trap
The NIBCO U5885 uses ABS for DWV P-traps with a solvent weld joint. It supports service temperatures from -40°F to 180°F and is designed for DWV applications. Best for ABS-based piping projects requiring a durable solvent-weld connection. Caution: not suitable for compressed air or gas testing environments.
Buying Guide
What to consider when buying a 2″ PVC glue trap:
- Material compatibility: PVC vs ABS vs other plastics. Choose based on your existing piping material and local codes.
- Connection type: Hub x Hub vs solvent-weld joints. Weld joints offer a permanent seal but require proper primer and cement.
- Intended use: DWV versus floor drain seals. DWV traps are for line gas control; seals are useful where evaporation is common.
- Temperature range: Ensure the trap will operate within system temperatures (often up to 140°F for DWV components).
- Installation environment: Indoor vs outdoor, exposure to chemicals, or heavy use areas may affect material choice.
- Maintenance and reliability: Consider seals or traps designed to minimize evaporation or gas ingress.
FAQ
- What is a DWV P-trap best used for?
DWV P-traps seal drains to prevent sewer gases from entering occupied spaces while allowing wastewater to flow freely.
- Can I mix ABS and PVC traps in the same system?
Typically not recommended; use matching materials for solvent-weld connections unless adapters are specified by code or manufacturer.
- What does solvent weld mean?
A method using primer and cement to fuse pipe and fitting ends into a single, leak-proof joint.
- Is a trap seal different from a P-trap?
A trap seal refers to the water barrier inside a P-trap; a P-trap is the entire U-shaped fitting that creates that seal.
- Are 2″ traps suitable for all residential drains?
Most residential 2″ drains use 2″ P-traps; confirm pipe size and building codes for your project.
- What is a floor drain trap seal used for?
It helps prevent trap seal evaporation and gas entry in floor or mop sink drains where evaporation risk is higher.
