Product Overview
The Midland 970-330 Cast Brass Square Head Cleanout Plug is a durable and reliable component designed for various plumbing, heating, pneumatic, and marine applications. Manufactured from smooth-cored castings, this bronze threaded fitting ensures full flow with minimum restriction. Its threads are precisely machined and gauged for a perfect fit with pipes, and each fitting undergoes individual water testing to guarantee quality. Bronze construction offers a tighter seal and easier installation compared to other metals, along with excellent resistance to corrosion from salt water or fresh water polluted with mineral acids or peaty soils.
Key Features:
- Approved to ANSI/NSF 61-4 California AB 1953 standards.
- Meets federal and state drinking water act lead-free requirements.
- Brass fittings conform to AWWA C800 specifications.
- Brass castings conform to ASTM B584, UNS alloy C8933 standards.
- Brass fittings dimensions conform to ASME B16.15 standards.

Installation and Setup
Proper installation is crucial for the effective and leak-free operation of the cleanout plug. Follow these general guidelines:
- Preparation: Ensure the pipe opening or fitting where the plug will be installed is clean, free of debris, and has intact threads.
- Thread Sealing: Apply an appropriate thread sealant (e.g., PTFE tape or pipe thread compound) to the male threads of the cleanout plug. This helps create a watertight seal and prevents galling.
- Hand Tightening: Carefully align the plug with the threaded opening and hand-tighten it until snug. Avoid cross-threading.
- Final Tightening: Use a wrench on the square head of the plug to tighten it further. Apply sufficient torque to create a secure seal, but do not overtighten, as this can damage the threads or the fitting. Refer to local plumbing codes and best practices for specific torque recommendations if available.
- Leak Check: After installation, if the system is under pressure, check for any leaks around the plug. If leaks are detected, re-tighten slightly or re-apply thread sealant.
Note: Always consult local plumbing codes and regulations for specific installation requirements in your area.
Operating Principles
The Midland 970-330 Cleanout Plug serves as a removable seal for cleanout access points in drainage or plumbing systems. Its primary function is to provide a secure, leak-proof closure while allowing easy access for inspection, cleaning, or clearing blockages when needed. The square head design facilitates easy removal and re-installation using standard tools.
Maintenance
The brass construction of the Midland 970-330 plug offers inherent corrosion resistance, minimizing the need for extensive maintenance. However, periodic inspection and care can prolong its lifespan and ensure continued reliable performance:
- Inspection: Periodically check the plug and surrounding threads for any signs of corrosion, damage, or leaks.
- Cleaning: If the plug is removed for system access, clean any debris or sealant residue from its threads and the mating pipe threads before re-installation. A soft brush and mild detergent can be used if necessary.
- Lubrication/Sealant: Always re-apply fresh thread sealant when re-installing the plug to ensure a proper seal.
- Storage: If removed and stored, keep the plug in a clean, dry environment to prevent accumulation of dirt or foreign matter.
Troubleshooting
Most issues related to cleanout plugs are minor and can be resolved with simple steps:
| Problem | Possible Cause | Solution |
|---|---|---|
| Leakage around the plug | Insufficient thread sealant; damaged threads; plug not tightened enough. | Remove the plug, clean threads, re-apply fresh thread sealant generously, and re-install, ensuring proper tightening. Inspect threads for damage; replace if necessary. |
| Difficulty removing the plug | Overtightening; corrosion buildup; old, hardened sealant. | Apply penetrating oil around the threads and let it sit. Use a suitable wrench for leverage. If severely stuck, professional assistance may be required. |
| Plug feels loose after installation | Not tightened sufficiently; incorrect thread size. | Ensure the plug is the correct size for the fitting. Re-tighten the plug using a wrench. If threads are stripped, the fitting or plug may need replacement. |
