Rubber Test Balloon Pipe Plug,Inflatable Test Plug with Air or Water, Test Plug Plumbing
Maximum Inflation Pressure 40 PSI
2 inch Inflatable Plumbing Test Plug
Schrader valve be inflated using a standard bicycle pump

Seals&holds pressure:
The test plug plumbing is made of natural rubber for good air-tightness, elasticity, expansion and memory, durable and not easily leakage. More flexible and expandable than traditional fixed-size plugs while testing a piping system.

Must-have test pipe plug:
The hydraulic test plug can be used in various types of pipes, such as shower pipes/ floor drains/ bathtub pipes/ bathroom plumbings/ toilet tees/ swimming pool pipes/ basement drains/ under ground sewage lines.
The pneumatic test bladder is great for plugging the drain pipe/vent/sink/wastewater systems to test PVC pipe, shower pan or sanitary tee and other inaccessible pipe openings for leaks, detect plumbing or boat fuel tanks pressure.

Simple to use:
Insert the inflatable drain plug into the water hose and slowly inflate it with a standard bicycle pump to open the water and it will test properly. After the plumbing test bladder has been properly removed from the air, pull it out using the loop handle.

Warm tips:
Surface damage and deformation can not continue to use; stored in a cool place.
When the drain pipe is deep, it is recommended to use an extension hose for ease of use.
Insert the test sewer bladder into the pipe for a distance at least equal to the diameter of the pipe.
Operate the bicycle pump slowly, do not exceed the specified inflation pressure (Preferably below 40 PSI).
When drain test bladder is used, there is a conical danger zone that extends outward; do not enter the danger zone.
