Flowstop Services perform a wide range of Under Pressure Drillings and Hot Tap Drillings, using a variety of drills and tapping machines. We are able to drill anything from 1" up to 48" on mains running at LP to IP. 

Under pressure drilling is the process of drilling a hole into a live pipe system without the need to depressurise the main and maintain the flow. All of this is carried out in a gas free environment.

Our drilling machines are kept to the highest standards and are operated by experienced and fully qualified engineers.
