Commercial Line Stopping Services

What is Water Line Stopping?

line tapping services

A line stop is performed while the existing main is under pressure and enables “point shut-down” of a main when a permanent valve is unnecessary and the shut-off required is temporary (less than 3 days).

Advantages of Line Stopping

  • Reduces costs significantly as compared to traditional methods
  • Saves time in repair and replacement services
  • Eliminates sediment fallout and pipe damage which result from de-pressurization.
  • Protects water flow for customers, including emergency and operational services

Water Line Stopping & Pipeline Plugging Services

For municipal line stopping, Mickie Service Company is the leading provider in the Gulf Coast region. Our line stopping services (also called line stop) provides a temporary shut-off of an existing water main.

Line stops can be “single” when flow is in a single direction or “double” for a grid, bi-directional flow situation. The line stops enable “point shut-down” of a main with dramatically reduced water loss, service interruption, and damage to infrastructure resulting from water main de-pressurization.

A line stop is performed while the existing main is under pressure. A size-on-size tap is made on the top of the main and a rubber plug or stopper is inserted into the line. The plug is then pumped into the main using a hydraulic ram (the main is supported by the line stop sleeve) which shuts off the water flow. After performing the necessary service, the stop is removed, and a blind flange is installed on the sleeve.

Line stopping is the preferred approach when the shut-off required is temporary (less than 3 days). We stock line stock fittings 4"-60" in all standard sizes, minimizing customer delay resulting from underground pipe uncertainty. 


Water Line Stop Materials & Sizes

The system works on any commonly used pipe including cast iron, asbestos-cement, steel, ductile iron and PVC.  We offer line stops from 4 inches to 16 inches, ranging up to 150 psi. We offer same or next day service in most cases.


Municipal Water Line Main Stopping Services

If you are in need of a permanent valve solution, we offer municipal insertion valve service, as well. Mickie Service Company’s Line Stopping significantly reduces or eliminates overtime costs, and decreases repair and routine maintenance time.
