Waters Mechanical Inc. is in the business of solving HVAC piping problems where the system is in operation and needs modification. When tying in new piping to an existing system and the system cannot be shut down or drained we have the solution.
Wet taps (also known as hot taps and pressure taps) can add branch lines to an existing line of the same size or smaller. This operation consists of welding in a thread-o-let or flanged pipe spool to the existing pipe. Next a valve is installed and the tapping machine drills through the newly installed valve. The drill is withdrawn through the valve, the valve closes, and the tapping machine is removed. The completed work ends with a valve installed on the existing main, ready for any piping connections.
Common uses for wet taps include: chilled water and condenser water systems, plumbing for domestic cold or hot water piping, and fire sprinkler piping.
For sizes of half inch through two inch we use a full port ball valve and for valves two and one-half inch and greater we install a flanged gate valve. Our present capabilities are half inch through eight inch nominal pipe sizes.
