A water shut off tool can be used to shut water off at the street, main or pipe. Options such as meter, gas and water valve keys, can turn city water on and off either underground or above ground, by either squeezing, crimping or using a key to turn a valve.
A water shutoff tool allows you to squeeze down copper or plastic pipe to stop the flow of water or other liquids in a pipe to conduct a service. Squeeze off tools come in a variety of sizes from 1/2"- 8" and are manually or hydraulic driven. Whether you are shutting off city water or access to a main water valve, a poly squeeze off tool is the best option. All Reed Mfg, tools use positive stops to prevent damage caused by over clamping.
How To Use a Pipe Shut Off Tool
Step 1: ✅ Follow all safety procedures.
Step 2: ✅ Determine pipe/tube size and wall thickness to be squeezed. Set stops for over-squeeze protection.
Step 3: ✅ Assemble tool handle where desired.
Step 4: ✅ Insert ground probe into moist soil.
Step 5: ✅ Unscrew the main pressure screw.
Step 6: ✅ Lift and swing bottom bar.
Step 7: ✅ Center the squeeze-off tool on and square to pipe. This will allow pipe to flatten without jamming pipe against tie rods.
Step 8: ✅ Swing bar back over tie rods.
Step 9: ✅ Turn the feed screw to compress the pipe at a slow rate with momentary pauses to allow stress relaxation in the pipe to occur. This is particularly important when pipe is stiff in cold weather.
Step 10: ✅ Squeeze the pipe only until flow is controlled or bottom bar contacts over-squeeze protection stops. Operation beyond this point may cause damage to pipe or tool.
Tool Removal
1. A release rate of 1/2 inch per minute or less should be maintained to prevent damage to pipe as recommended by ASTM F1041.
2. Rerounding the pipe can be done by rotating tool 90˚ and applying enough force to round pipe.
3. Inspect squeezed section for damage before covering. Procedures should be followed that will prevent the same area to be squeezed-off more than once.
Safety
Pressure control situations requiring squeeze-off may involve working in the vicinity of escaping gas. Consider the possibility and potential hazard of static electricity and observe safety precautions. Precautions can be taken to dissipate the charge, and minimize the possibility of an ignition. This will maximize the personal safety of the crew. These precautions should be followed as a minimum, conditions may require additional measures.
• ✅ To provide dissipation for static charge, wet down surfaces with conductive fluids and/or apply conductive films or fabrics to the pipe. Keep precautions in place until procedures are complete. • ✅ Ground all tools. • ✅ Periodically verify that continuity is maintained from ground probe to tool.* Check the squeeze-off tool prior to use to assure it is the correct size; is properly functioning; and is properly adjusted for the squeeze-off to be done.
