Municipal Water Insertion Valves

What is an Insertion Valve?

Municipal insertion valve picture

An insertion valve is utilized while installing a permanent valve on a water main. The insertion valve can be installed under full pressure and does not require the water main to be temporarily shut down. This is an ideal solution for water main maintenance, pipeline repair, and emergency valve replacement.

Advantages of Insertion Valves

  • Install new service lines, or expand the existing main line with no service disruption
  • Replace or repair valves and hydrants
  • Control water distribution for safe working conditions
  • Perform main line maintenance quickly and efficiently

Water Valve Insertion

Our municipal water valve insertion and installation service provide a permanent valve on an existing water main. Mickie Service Company is the leading provider of insertion valves in the gulf coast region. There are several names for water valve insertion that you might have seen including:

  • InstaValve
  • InsertValve
  • Inline Valve
  • Add-a-Valve
  • Insert-a-Valve

The insertion valves are installed while the existing main is under pressure. The use of an insertion valve enables the installation of a valve with no water loss, service interruption, or damage to infrastructure resulting from water main de-pressurization. The insertion valve is installed by making a size-on-size tap, generally in the top of the main, then inserting the valve body in the flange of the insertion valve fitting.

After installing the valve, a standard operating nut is installed and the insertion valve operates like any standard valve in the water system. An insertion valve is preferred when a permanent valve is required or when the shut off required is temporary.
