Carrhill TP34SB Pneumatic-hydraulic Test Plug 3-4 in

Product Description

The CARRHILL TP34SB is a pneumatic-hydraulic test plug designed for pressure testing drain, waste, and vent (DWV) pipe systems. It fits pipe diameters from 3 inches to 4 inches, making it a versatile tool for plumbing inspections and leak testing. The plug seals the pipe opening when inflated or pressurized, allowing the technician to apply air or water pressure to verify system integrity before the line is put into service. Plumbers and plumbing inspectors use this type of plug during rough-in inspections and final testing.

This test plug is suited for residential and light commercial plumbing applications where 3-inch or 4-inch pipe is used in DWV systems. It is typically deployed during new construction rough-in or repair work to isolate a section of pipe for pressure or flow testing. The pneumatic-hydraulic design allows the technician to choose air or water as the test medium depending on job requirements and local code.

Key Features

• Fits 3-inch to 4-inch pipe diameter range for versatile field use
• Dual pneumatic-hydraulic design supports both air and water pressure testing
• Inflatable plug body creates a reliable seal against pipe walls
• Suitable for DWV system testing during new construction and remodel work

Compatibility

Designed as an OEM-style test plug for use in 3-inch to 4-inch diameter plumbing pipe systems during pneumatic or hydraulic pressure testing procedures.

Installation Notes

Installation is performed by licensed plumbers or plumbing inspectors. Before testing, ensure the pipe section is clear of debris and that all downstream connections are capped or isolated. Insert the plug to the required depth and inflate to the manufacturer-rated pressure before applying test pressure to the system. Follow local plumbing code requirements, such as those outlined in the IPC or applicable state code, for minimum test pressure values and hold times.
