I thought I would post a few photos from the wet tap we did this week. The wet tap is when you tap into a live water or sewer line. We tapped into the citys 16″ water line with a 12″ main for the 225 townhomes we our doing at present.
#7 Shows the 16″main under pressure being drilled
#8 The drill (about $35,000 with bits)
#11 The business end
#14 Our 12″ main with shut off tied into the city 16″ main
It took the outfit that only drilled & hooked up the parts about 2hrs to do the job $2,300.00 invoice. After speaking to the 1 man crew that did the work, he informed me that in a good week he does 10+ taps $$$$ Good work if you can stay busy!

They don't. That is how come it cost so much.

Go Stab yourself Ya Putz! Ya think I Parked here?
G,
I need you to explain this to me. I would think this could not be done, but in looking at the pics, it's seems simpler than it should be.
Do you install the 12" shut off, then just run the holesaw through the assembly, closing the shut off when the bit it past it?

the city ran a new waterline for me a few years ago, just the usual single family home scene, its just like a large "saddle valve", the tool operater hardly got wetcaulking is not a piece of trim
Jon,
Like Steve said, he started with the large stainless steel no hub saddle fitting in the back of the first picture. Then he installed the red valve to that. Hooked up his drill with the blue bell fitting end. He did a air test with soap before he did any drilling. Opened the valve & started drilling , took about 10 mins to go through the pipe. At the bottom end of the drill there is 2 gauges when the numbers on both gauges matched ment that he was through the 16" main. Close red valve & remove drill. The plug came off with little effort ( some beating on the side of the plug) very clean cut on the plug, The wall thickness of the 16" main was close to 1/2" .
One last thing, all of this work was done on a busy 4 lane street (2 lanes each directions) had to re-direct traffic & had to be done by sun down with the street opened back up. The temp never got above 25. Used 28 yards of flash fill to close up the hole
