4. Installation Instructions
Follow these steps for proper installation of the Westbrass 442P PVC Straight Adapter:
- Prepare the Tub Drain: Ensure the tub drain assembly is properly installed in the bathtub and ready for connection to the plumbing system. The adapter's 1-1/2 inch NPMS thread will connect to the tub drain shoe.
- Prepare the PVC Pipe: Cut the 1-1/2 inch Schedule 40 PVC pipe to the required length to connect to the adapter's slip inlet. Ensure the cut is clean and deburred.
- Dry Fit: Perform a dry fit of the adapter to the tub drain and the PVC pipe to ensure proper alignment and fit before applying primer and cement.
- Apply Primer and Cement: Apply PVC primer to the outside of the PVC pipe and the inside of the adapter's slip inlet. Allow the primer to dry according to the manufacturer's instructions. Then, apply PVC solvent cement to the same surfaces.
- Connect PVC Pipe: Immediately insert the PVC pipe into the adapter's slip inlet with a quarter turn to ensure even distribution of cement. Hold firmly for at least 30 seconds to allow the cement to set.
- Connect to Tub Drain: Thread the adapter onto the 1-1/2 inch NPMS thread of the tub drain shoe. Hand-tighten initially, then use a wrench to secure the connection, ensuring not to overtighten. Use appropriate thread sealant if recommended by the tub drain manufacturer.
- Test for Leaks: Once the cement has cured (refer to cement manufacturer's instructions for curing time), turn on the water supply and fill the tub to test for any leaks at the connections.
5. Operating Instructions
The Westbrass 442P PVC Straight Adapter is a passive plumbing component and does not require operational steps. Its function is to provide a secure connection within the plumbing system.
6. Maintenance
- Regularly inspect all plumbing connections for any signs of leaks or damage.
- Clean the exterior surfaces of the adapter with mild soap and water if necessary. Avoid abrasive cleaners that could damage the PVC material.
- Ensure that no excessive stress or weight is placed on the plumbing connections.
7. Troubleshooting
- Leaks at Threaded Connection: If leaks occur at the threaded connection to the tub drain, ensure the connection is adequately tightened (without overtightening) and that an appropriate thread sealant was used. Disassemble, reapply sealant, and re-tighten if necessary.
- Leaks at Slip Inlet Connection: If leaks occur at the solvent-welded slip inlet, this typically indicates improper application of PVC primer and cement or insufficient curing time. The connection may need to be cut out and re-done with new components and proper technique.
- Difficulty Fitting: If the adapter does not fit the tub drain or PVC pipe, verify that the sizes (1-1/2 inch NPMS thread and 1-1/2 inch Schedule 40 PVC) match the components you are trying to connect.
