4. Installation Instructions
This section provides general guidelines for installing the Plumb Pak PP20925 continuous waste. Specific configurations may vary.
Tools You May Need:
- Adjustable wrench or slip-joint pliers
- Bucket or pan (to catch residual water)
- Rag or towel
- Hacksaw or PVC cutter (if pipe trimming is required)
Installation Steps:
- Prepare the Area: Turn off the water supply to the sink. Place a bucket or pan under the existing drain assembly to catch any water. Remove the old drain assembly if present.
- Connect Tailpieces to Sink Drains: Attach the tailpieces from your sink drains (not included with this product) to the sink basket strainers. Ensure a good seal with plumbers putty or a gasket.
- Assemble the Baffle Tee: Connect the baffle tee to one of the sink tailpieces. The baffle tee is designed to direct water flow from both sink bowls into the trap. Ensure the slip nuts and washers are correctly positioned and tightened by hand, then snug with pliers.
- Attach Continuous Waste Pipe: Connect the 16-inch continuous waste pipe from the other sink tailpiece to the baffle tee. This pipe runs horizontally between the two sink drains. Adjust the length if necessary by cutting the pipe with a hacksaw or PVC cutter, ensuring clean, straight cuts.
- Connect to P-Trap: Attach the outlet of the baffle tee to your existing P-trap assembly. If installing a new P-trap, ensure it is correctly aligned with the wall or floor drain.
- Tighten All Connections: Hand-tighten all slip nuts first, then use an adjustable wrench or pliers to snug them an additional quarter to half turn. Be careful not to overtighten, especially with plastic components.
- Test for Leaks: Turn on the water supply and fill both sink bowls. Remove the stoppers and observe all connections for any signs of leaks. If leaks occur, tighten the affected connection slightly.
5. Operation
The Plumb Pak PP20925 continuous waste system operates passively by directing wastewater from two sink bowls into a single P-trap. Once installed correctly, water will flow from the sink drains through the tailpieces, into the continuous waste pipe and baffle tee, and then down into the P-trap and main drain line.
Ensure that sink stoppers are functioning correctly to prevent accidental overflow. Avoid pouring harsh chemicals down the drain, as they can damage plastic plumbing components over time.
6. Maintenance
Regular maintenance helps ensure the longevity and proper function of your continuous waste assembly.
- Leak Checks: Periodically inspect all connections for any signs of leaks, especially after heavy use or if you notice water under the sink.
- Cleaning: If clogs occur, disassemble the slip joint connections to clean out any debris. Avoid using chemical drain cleaners that can corrode or damage plastic pipes. A plumbing snake or a mixture of baking soda and vinegar followed by hot water can be effective for minor clogs.
- Preventative Measures: Use sink strainers to catch food particles and other debris before they enter the drain system.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Leaks at Connections | Loose slip nut, misaligned washer, damaged washer. | Tighten slip nuts (do not overtighten). Check washer alignment and condition; replace if damaged. |
| Slow Drainage / Clog | Accumulation of food particles, grease, or hair. | Disassemble and clean the continuous waste pipe and baffle tee. Use a plumbing snake for deeper clogs. Avoid chemical drain cleaners. |
| Water Backing Up | Severe clog in the P-trap or main drain line. | Clear the P-trap. If the problem persists, the clog may be further down the main drain, requiring professional assistance. |
