Types of Plumbers’ Plugs
1. Cherne Test Plugs
Cherne test plugs are widely recognized in the plumbing industry for their reliability. Made from high-quality rubber, these plugs come in a variety of sizes ranging from 1″ to 48″. They are designed for pressure testing and maintenance, holding back pressures of up to 13 PSIG. Perfect for both residential and commercial applications, Cherne plugs are a favorite among professionals.
2. PVC DWV Test Plugs
PVC DWV test plugs are lightweight and easy to handle, making them ideal for drainage, waste, and vent systems. These plugs typically range from 2″ to 6″ in size and are specifically designed for low-pressure applications. Their use is vital for ensuring that drainage systems are functioning correctly before they are put into service.
3. Wing Nut Isolation Plugs
Wing nut isolation plugs offer a quick and effective sealing solution for various applications. Made with neoprene seals and die-cast bodies, these plugs are rated to hold back pressure up to 13 PSIG. They come in sizes ranging from 2″ to 24″, making them versatile for different projects. These plugs are particularly useful in situations that require rapid isolation of pipelines.
4. Inflatable Pipe Plugs
Inflatable pipe plugs are designed to seal larger pipes or irregular openings. They are highly flexible and can adjust to different pipe sizes ranging from 3″ to 36″. These plugs are often used in situations requiring temporary sealing of pipes for testing or maintenance. Their inflatable nature allows them to conform tightly, ensuring a secure seal.
5. Gripper Test Plugs
Gripper test plugs combine the benefits of PVC and rubber materials for versatility and durability. These plugs are primarily used for testing drainage and vent systems, with sizes typically ranging from 1″ to 12″. They are suitable for low-pressure applications and are essential for identifying leaks or blockages before full system activation.
Applications of Plumbers’ Plugs
1. Testing and Maintenance
Plumbers’ plugs are commonly used for testing the integrity of plumbing systems. By temporarily sealing pipes, plumbers can apply pressure to check for leaks and ensure that the system is functioning correctly. This application is crucial for both new installations and existing systems requiring maintenance.
2. Emergency Repairs
In emergency situations, plumbers’ plugs can provide a quick fix to stop leaks. By sealing off a leaking section of pipe, these plugs can prevent water damage and allow for repairs to be made without the need for immediate pipe replacement.
3. Isolation of Sections
When performing repairs or maintenance on specific sections of a plumbing system, isolation plugs can be used to seal off those areas. This allows for work to be done safely and efficiently without affecting the entire system.
4. Drainage and Waste Systems
Many plumbers’ plugs are specifically designed for use in drainage and waste systems. They help to test these systems before they are put into service, ensuring they can handle the expected flow and pressure.
