Jeff Maichel (President)
Choose your Linestop® Company Wisely We have 33+ Years of Linestops, Leadership & Innovation. IFT has been proven to be one of America’s most Advanced Municipal & Commercial Linestop Service Providers.

The Rancho California treatment plant in Murrieta, California, asked International Flow to perform an unusual 24" Linestop™ on a 90 degree bend. This video shows the unusual 24" Linestop™ that allowed the Sewage treatment plant to remain in service while changing out their broken Plug valve. IFT designed changes to its machinery to allow this operation and successfully plugged the elbow. The valve was then replaced under pressure. After the project, IFT was contracted to replace 3 additional 24” valves on similar 24” elbows.

Pipe Linestop Sizes and Options:

54-60inch LinestopsSizes and Bypass Options: 1/2” through 72” Line stopping capabilities.  Our equipment has optional by-pass capabilities through the machinery, which eliminate the need for additional bypass taps. IFT offers “Full size” built-in bypasses on machinery through 48” if flow concerns are an issue.

Folding head machinery is available for reduced entry, at a reduced cost and weight; with a reduced by-pass size as well. Numerous Linestop® machines can be used to isolate and by-pass a system. For example: 4 way tees allow a bypass to each leg without a separate bypass tap.
