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.

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

@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 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

@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 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 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 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
