Hot Tap Into Water Main

[ASCOWAGSLTD]

Check out my hot tapping on a live chilled water pipe, we also do gas, compressed Air, steam and water. ASCOWAGSLTD

Interesting video, do you still do sewer and water work?

[mic88ed]

Wow' in Houston we normaly shut off the main.

[AlanMolstad]

Nice areas to work in,

Good rock to stand on, good pump getting rid of the ground water...not a bad place to work!

[mansuri11]

explosive tee's much more fun to install, look them up

[tjones2269]

you didnt pressure test your taping sleve to make shure no drips before you cut it

[AlanMolstad]

@tjones2269

We never use that thing too...

I always check it to make sure it's tight, but we dont have to do anything with it

[tjones2269]

city inspectors around here made us test it before they would let us start to cut have to pump it up to 120 psi and hold it for 5 min

[AlanMolstad]

interesting.....

[spoterkill]

@tjones2269 test the valve before you cut,thats stupid you'd only be testing one flange ,i'm confused so what did you have to do rod a cap on the valve so you can test it.we test 200 psi

[tjones2269]

@spoterkill yeah mount the taping sleve and valve get it all tight then they would cap off the other side of the valve and on the cap was bolted on it had a hose in the middle witch went up to a hand pump remove that plug on the ss sleve start pumping till water came out to get all of the air out put the plug back in then they would pump it up and let it sit to make shure it all was good the taping sleve seal and valve before they tapped the live main the city inspectors sat and watched

[spoterkill]

@tjones2269 how do you pump up a live water main that make no sense

[d4c24a]

@spoterkill what we do ,is fit the underpressure tee and valve ,we then pump up to 16 bar ,check that the underprssure tee is not leaking ,you can then cut the main

if you cut without testing ,you may have a leak that may well require a shut down to stop

[spoterkill]

@d4c24a but you'd only be testing one flange what the point.besides your wet-tap contracter,atleast we never do it .should provide a go to go fitting. sound like buddy had a cunt of an inspector where was it coquitlam?

[d4c24a]

@spoterkill you are also testing the tee ,as this can fail to seal ,you have a possible leak at the flange connecting the valve to the tee ,and also the seal between the tee and the existing main, this is the one you are missing ,if you drill without testing and it leaks ,you are up shit creek

and will require a shut down

[spoterkill]

@d4c24a who knows maybe the wet-tap guys do test it before they drill we don't install the valve our selfs so.i just get the hole ready for them and come back in an hour when there done and do my tie-in .so anyways i'm more or less done arguing about it lol i like your vids ,that d4 would be perfect on my old mans property what year is it?

[d4c24a]

@spoterkill no argument ,just how things are done in a differant way over the pond

we do it all ,dig it ,fit ,drill and connect lay the main backfill chlorinate pressure test ,etc etc ,no blacktop some one else

The D4 is 1962 and was stood for many years ,and although i have done little cosmetic work ,mecanicly i have done a lot , engine rebuild ,liners rings ,shells

it had around 90% running gear ,apart from the plates which were smooth ,i found some good useables ones for free cheers

[hillendrocky]

Quicker and cheaper doing a cut out , couple of vj ,s bolt up makes it more secure

Where is the coupon ?

[PorkChop355]

You mean proof of purchase.

Hey guys, is water mains maintenence etc done in America by private contractors or employees of the city/state. I work for the government here in Ireland as a plumber fixing burst mains are completing new tap ins but i would love to work in America for a year or two just to see how it all works over there. Any info greatly appreciated.

[2drew1]

my last projects for the government was, slab work for a the outdoor maintance facility which included two

bathrooms, a shower, eye wash station and hand sinks. another

project we did was a complete watermain repipe of a complex using

2' pvc (they previously [back in the late 70s early 80s] used

galvanized pipe [which over time rusts inside and reduces the

pressure to an unusable amount]

[2drew1]

another project we have done

for the government was to install a 8'' b.f.p. (back flow

preventor) which was above ground in a hot house that we also

assembled. we also done repairs on a few of the facilities, one

such repair was to 4" cast iron roof drains that were clogged

with roofing tar. we also did a additionial bathroom for a college

which consisted of several toilets and urials. wish i had pictures

to show you all the crazy jobs ive done over here

[hyperw9]

is this tappin 4 a fire hydrant or sumthin.......an also is da mains ci ( cast iron)

[penneygriffin]

Is anyone on this website from Georgia?

[ditchdiggr]

the shavings stay in the drill bit hub, but the iron build up on the inside of iron pipe or some of the cement lining on ductile iron will break off and stay in the sytem untill flushed from a hydrant.

[VeryGoodQuestion]

Whats the tapping band made of? Looks like stainless steel?

[kimchiman1000]

Don't know. This was my first time seeing a live tap done. So far it's been the only time.

[brino7900]

It is stainless

[penneygriffin]

We call it a stainless Fabricated sleeve. As far as I know there are two kinds of sleeves Fabricated and Mechanical Joint aka MJ.

Two kinds of fabricated are the wrap around stainless and the other is a two piece that has a doughnut shaped gasket inside around the entrance.

[spoterkill]

@VeryGoodQuestion diamonds tip steel

[xWarPx]

Wouldn't metal shavings go into the pipe being tapped and ruin someones day/appliance?

[kimchiman1000]

That was what I thought when I saw them do this, but they say they have a way to flush them out before they enter into the system. If I recall correctly, it is because the system is pressurized that when the drill bit starts going through the pipe's wall, the water forces the metal shavings out into a compartment in the drill, thus preventing that problem.

[penneygriffin]

I usually apply a tapping compound to the teeth. This does one of three things - It reduces friction so my carbide tips stay sharp, it takes less muscle to turn the handle while cutting. It also attaches to the shavings, so when I pull my machine off and remove the piece of cut pipe from the saw, behind it is a pile of pellets made up of compound and shavings. It looks like deer pellets. The pressure of the water also keeps the shavings in check.

[kimchiman1000]

Cool!

I usually apply tapping compound to my teeth as well. I save money on toothpaste.

(yeah, bad joke...)

Thanks for the info though.

[dripanijr]

The puncture of the main will blow water and the shavings into the barrel

[AlanMolstad]

We always have to flush the pipe for a moment before we start connecting pipe to the valve.

[chup123]

valves and fittings shouldnt be laid on grass

[gfpd2722]

why

[penneygriffin]

Valves and fittings are buried in dirt. So you can't lay them on grass? OOOOOKKKKK

[kimchiman1000]

The practice of laying gate valves on grass hurts nature, and makes the grass sad! It is disruptive to ant colonies as well.

I can't believe you didn't know this!

Al "A Convenient Lie" Gore has proved that gate valves on grass contribute to global warming by damaging the photosynthesis process in grass blades.

Now you know! (rolling eyes...)

(grin)

[penneygriffin]

Thanks Kimchiman1000 for your vast ecological knowledge :D.

I cut in 3/4" to 12" hot taps every day and had never heard that the valves and sleeves couldn't be laid on grass. I though maybe they would get grass stains that even Tide wouldn't get out.

Seriously, something I noticed odd about this tap, is that the operator has installed the gate valve to the sleeve before installation! Why? This would seem to make it extremely difficult to adjust the sleeve angle.

[KDET10]

Will be making one of these this week, 16x8 cut on route 541 in Mount Holly. At least you have nice looking equipment. I`m afraid our cut machine is gonna blow up every time we use it haha.

[kimchiman1000]

Just keep your fingers crossed, mate!

[Hduppln]

what is that existing line your crossing its either rcp or asbestos concrete?

[kimchiman1000]

concrete
