We are an approved installer of the "Insta-Valve" insertion valve system, an innovative alternative to a traditional mains shut or line stop. With this system, we are able to install a fully functional resilient seat gate valve without interruption to the water supply. 

USE Ltd can install Insta-Valves on cast iron, ductile iron, steel, and UPVC pipelines from 4-12" (DN100-DN300) diameters.

Reg 31 Compliance

Hydra-Stop and USE have worked together to bring a new UK version of this highly successful and innovative US product. The all-new Insta-Valve UK has been designed to be fully compliant with the provisions of Regulation 31 of The Water Supply (Water Quality) Regulations 2016; all components have been fully tested to comply with BS6920 and BS7766, allowing Water Utility Companies to be confident that the Insta-Valve can be installed with zero risk of contamination to their customers water supply.

Pipeline Integrity

The Insta-Valve installation process allows the valve body to be fitted, pressure tested, and cast into a concrete thrust block before the pipe is drilled. This is especially important for older cast-iron, PVC, or Asbestos Cement mains, which can easily fail during any cutting or drilling process - a correctly applied concrete thrust/support block will provide necessary protection to prevent this potentially catastrophic failure.

Limited Space Requirements

The Insta-Valve has a compact body - no larger than a standard under-pressure tee, and the installation process requires no more space than a standard line tap. This results in a product that can be installed in spaces congested with other services and obstacles. The Insta-Valve fits where many others will not!

Pipeline Inspection

Pipeline inspections can be carried out as part of the Insta-Valve installation process; a CCTV camera and hydrophone can be inserted into the pressurised main via a chlorinated camera entry port, providing the client with accurate data about the internal condition of the pipeline.
