Why shut down? Pacific Flow Control has been hot tapping Concrete Pressure Pipe (CPP) for over 40 years. Yesterday we completed a 20×12 AWWA C303 wet tap for the City of Calgary on a beautiful piece of bar-wrapped concrete pressure pipe. If you have PCCP (AWWA C301), RCCP (C303) or RCP pipe that you’d like to tap into, give us a call or e-mail, and we’ll walk with you through the process and get you any engineering for the fitting that you may need.
