1. Introduction
This manual provides essential information for the proper installation, operation, and maintenance of your Waterway Plastics 400-9820B Chlorinator Wall Fitting. This fitting is designed for use with swimming pool chlorinator systems, featuring a 1-1/2 inch Male Pipe Thread (MPT) connection on one end and a 1-1/2 inch Buttress (B) connection on the other.
Proper installation and regular maintenance are crucial for the longevity and efficient performance of this component within your pool's chemical dispensing system.
2. Safety Information
Always observe the following safety precautions when working with pool equipment and chemicals:
- Disconnect Power: Before performing any installation or maintenance, ensure all power to the pool pump and related equipment is disconnected at the circuit breaker.
- Wear Protective Gear: Always wear appropriate personal protective equipment (PPE), including safety glasses and chemical-resistant gloves, especially when handling pool chemicals or working near chemical lines.
- Chemical Handling: Refer to the manufacturer's instructions for any chemicals used in conjunction with the chlorinator. Never mix different pool chemicals.
- Pressure Warning: Pool plumbing systems can be under pressure. Relieve all pressure from the system before opening any lines or fittings.
- Professional Installation: If you are unsure about any installation steps, consult a qualified pool professional.

4. Setup and Installation
This fitting is designed for a secure, leak-free connection in your chlorinator system. Follow these steps for proper installation:
- Prepare the Connection Points: Ensure the male pipe thread (MPT) connection point on your chlorinator or plumbing line and the buttress (B) connection point are clean and free of debris.
- Apply Thread Sealant: For the 1-1/2" MPT side of the fitting, apply 3-5 wraps of PTFE thread seal tape clockwise around the threads. Ensure the tape is applied smoothly and covers all threads.
- Install O-rings/Gaskets: If your specific application or the "parts bag" includes O-rings or gaskets, place them correctly onto the fitting or the mating surface as required to ensure a watertight seal.
- Thread the Fitting: Carefully thread the 1-1/2" MPT end of the Waterway 400-9820B fitting into the corresponding female threaded port on your chlorinator or plumbing. Hand-tighten first to avoid cross-threading.
- Secure the Connection: Using an appropriate wrench, tighten the fitting an additional 1 to 2 turns past hand-tight. Do not overtighten, as this can crack the plastic or strip the threads.
- Connect the Buttress Side: Connect the 1-1/2" buttress side of the fitting to the mating buttress connection of your pool plumbing. Ensure the connection is secure and any associated union nuts are tightened properly.
- Leak Check: After installation, restore power and pressure to the system. Carefully inspect all connections for leaks. If leaks are detected, relieve pressure, re-tighten, or re-apply thread sealant as necessary.
5. Operating Principles
The Waterway Plastics 400-9820B Wall Fitting serves as a critical connection point within your swimming pool's chlorinator system. It facilitates the flow of chlorinated water from the chlorinator back into the pool's circulation system or connects the chlorinator to the main plumbing line.
Once installed, this fitting operates passively, ensuring a sealed pathway for water and chemicals. Its primary function is to provide a durable and leak-proof interface between different components of your pool's chemical dispensing setup.
6. Maintenance
Regular inspection and minor maintenance can extend the life of your fitting and prevent potential issues:
- Visual Inspection: Periodically inspect the fitting for any signs of cracks, discoloration, or wear, especially around the threaded connections.
- Leak Checks: Regularly check for any signs of water leaks around the fitting. Even small drips can indicate a developing problem.
- O-ring/Gasket Condition: If accessible, inspect any O-rings or gaskets for signs of drying, cracking, or compression set. Replace them if they appear damaged or are no longer providing a proper seal.
- Cleaning: If mineral deposits or chemical residue build up on the exterior of the fitting, gently clean it with a soft cloth and mild detergent. Avoid abrasive cleaners or solvents that could damage the plastic.
- Winterization: During winterization, ensure the fitting is drained of all water to prevent freezing and potential damage.
7. Troubleshooting
Most issues related to this fitting involve leaks. Here are common troubleshooting steps:
| Problem | Possible Cause | Solution |
|---|---|---|
| Water Leak at Threaded Connection | Insufficient PTFE tape; damaged threads; overtightened/undertightened connection. | Relieve system pressure. Disconnect fitting, clean threads, re-apply 3-5 wraps of fresh PTFE tape, and re-tighten. Ensure not to overtighten. Inspect threads for damage. |
| Water Leak at Buttress Connection | Damaged O-ring/gasket; loose union nut; debris in connection. | Relieve system pressure. Inspect O-ring/gasket for damage and replace if necessary. Clean connection surfaces. Ensure union nut is securely tightened. |
| Fitting Appears Cracked or Damaged | Physical impact; chemical degradation; overtightening during installation; freezing. | The fitting must be replaced. Ensure proper winterization to prevent freezing. |
