Valve Insertions

What is an Insertion Valve?

Valve insertion is the method of installing a permanent valve on an existing main water without interrupting service on that pipe. The primary alternative to an insertion valve is to use the existing valve infrastructure to shut down the water main(which generally results in a far larger section of infrastructure to be taken out of service) and then "cutting in" a new traditional valve.

Water main insertion valves are generally employed when existing valves are inoperable, cannot be located or are not positioned correctly to ensure isolation for critical infrastructure (municipal & commercial) and users (hospitals, schools, major lateral distribution mains)

We offer valves from different manufacturers to ensure we can provide the correct Insertion Valve Solution. There are multiple brands and names describing Insertion Valves - including, Valve Under Pressure (VUP), InstaValve, InsertValve, Inline Valve, Add-a-Valve, and Insert-a-Valve.

More about Insertion Valves

Advantages of Insertion Valves

  • Eliminates service disruption and water loss
  • Reduces scheduling variability (no need to coordinate the authorities on water main shutdown, which can often take multiple attempts)
  • Reduces excavation required, relative to the standard valve "cut-in"
  • Improves overall job safety - by eliminating the need to work in the wet, sloppy conditions that always exist when cutting a water main
  • Reduces risk of water main contamination
  • Reduces crew service time and off-peak hours scheduling
  • Saves time and costs, from start to finish
