Water Main Tapping Issue


We were tapping ductile water main today and ran into some issues. 1st tap went fine. With the second tap it seemed like there wasn't enough resistance no matter how tight we tightened bottom wheel. Took it apart and noticed the bit just made pin hole in pipe but wouldn't go further. Took it off that pipe and tried it on piece of pipe out of trench and worked like a charm.

So, we tried again on 2nd hole and still wouldn't go thru. Decide to try for another lateral and same thing happened. Went out and got Mueller machine and again nothing worked. First machine was a Reed. Bought a brand new bit so I don't think that is the problem.

Luckily this a new subdivision so there is no water in pipe. But we got 10 taps to do total so we need to get this resolved. Just wondering if anybody has had this problem before. We don't do a lot of tapping so it could be something fairly easy but by 7:30 we were so frustrated we called it a day. Thanks in advance.

Re: Water Main Tapping Issue


boy, that's odd....i was still using the mueller my dad had that he bought new in the fifties...other than replacing bids occasionally...worked like a charm.

although, mine was the old hand operated one..no electric or hydraulic drive motor.

on edit...did you call mueller customer service? they may have the answer...

i'm curious though...let me know what was going on?

All set now. We are thinking it was a defective bit. Nobody had bit in stock so i took 3 older ones to a sharpening place and everything went fine after that. Finished the 2 that didn't go yesterday and did 7 additional today. We went old school and did them by hand even though we had electric drive. They turned water on and no corps. leaked so in the end everything is good.

Re: Water Main Tapping Issue


Why was there no water in the line ?? Are you required to hydrostatic test the main ?? Around here they test and flush then do the wet taps.

It's hard to get water dept. to do much. We did the main then tested. They didn't have time to take samples so we did taps. There was water in line so city guy would open gate to road and we checked all taps and services to make sure nothing was leaking. Being a new subdivision it wasn't a big deal.
